A sinewave tone of one constant frequency is generated in the left channel of a stereo track, and a series of changing tones of slightly different frequencies are generated in the right. In addition, a stereo "surf" noise is generated. The differences between the left- and right-channel frequencies are termed "beat frequencies".
+
== Installing plug-ins ==
{{Hint|1=According to published research, listening to these beat frequencies can cause the main brainwave frequency to "align" with the beat frequencies through a phenomenon called {{external|[http://web-us.com/thescience.htm entrainment]}}. The beat frequencies might result in different states of awareness, including increased relaxation or alertness, lucid dreaming or many other states. The four most familiar brainwave frequencies are:

To install Nyquist plug-ins in Audacity, follow the instructions in the Audacity manual:
*Beta (14-21 Hz and higher)
+
*'''[https://manual.audacityteam.org/man/installing_effect_generator_and_analyzer_plug_ins_on_windows.html#nyquist_install Windows instructions]'''
*Alpha (7-14 Hz)
+
*'''[https://manual.audacityteam.org/man/installing_effect_generator_and_analyzer_plug_ins_on_mac_os_x.html#nyquist_install Mac instructions]'''  
*Theta (4-7 Hz)
+
*'''[https://manual.audacityteam.org/man/installing_effect_generator_and_analyzer_plug_ins_on_linux.html#nyquist_install Linux instructions]'''
*Delta (0-4 Hz).
 
Research suggests there are many variations on these bands as well as additional brainwave frequencies, and that different states may be associated each.<br>

==Compatibility==
 +
These plug-ins were contributed over many years, and many versions of Audacity. In the vast majority of cases, old plug-ins should continue to work in more recent versions of Audacity. More recent Nyquist effects may not install in old versions of Audacity or may not work correctly.
 +
{{advice|It is highly recommended to use the latest release version of Audacity, which is available via the [https://www.audacityteam.org/download/ Audacity website].}}
  
#'''Left channel tone frequency:''' from 50 Hz to 1000 Hz (default 100 Hz).
+
<div id="list"></div>
#'''Beat frequency [Hz], duration [minutes], time to change to next beat frequency [minutes]:''' There are six of these edit fields in which you may enter up to three indicated values, separated by a space. The first of these edit fields has default values of 17.5 0.25 0.25. In the sixth field you may enter a final beat frequency and duration of that frequency. If you enter a only a single value into any of these fields, the duration of that beat frequency will be zero. If you leave any of these edit fields blank they will be ignored.
 
#'''Adjust total time:''' between 1 and 60 minutes [0=no adjustment].
 
#'''Fade-in and fade-out times:''' [seconds]. Sets the time for fading in and fading out the volume at the start and end of the generated audio.
 
#'''Stereo surf frequency:''' from 0 Hz to 2 Hz (default 0.1 Hz). If this setting is above zero, the surf sound will be panned back and forth somewhere between the left and right audio channels at the specified frequency, how far depending on the sixth variable:
 
#'''Stereo surf spread:''' [percent] between 0 and 100 percent (default 80%). The larger this number, the further the surf sound will move away from the center pan position (0% results in the surf sound remaining in the center).
 
#'''Tone to surf volume ratio:''' [percent] from 0 to 100 percent (default 70%). Adjusts the relative volume of the tones and surf sound.

Generates a nasal-sounding tone composed of the base frequency combined with a number of harmonics. If for example you choose a frequency of 100 Hz with four harmonics, this plug-in will generate a tone comprised of 100, 200, 300 and 400 Hz, of equal amplitude. (The more harmonics, the more nasal and high-pitched the tone sounds). Although the original Nyquist code asks for a MIDI note number rather than a frequency, this plug-in allows you to choose between the frequency (e.g. 440 Hz) and the MIDI note number (57). (0=frequency, 1=MIDI note number.) You may choose the number of harmonics, tone and appended silence duration.

Author: Steven Jones. Generates sounds by mixing narrow bands of noise. The center frequency of each band is harmonically related to the fundamental and the amplitude decreases inversely with the harmonic number. Depending on the width of the band, the result can sound very noisy or distinctly tonal with a heavy chorusing effect.
 
 
 
Parameters:
 
 
 
#'''MIDI Note List:''' A list of MIDI notes to be produced. Each note must be separated by at least one space and punctuation is not allowed. Notes are specified either by an integer or by a Nyquist mnemonic.
 
#'''Number of Harmonics:''' An integer between 1 and 32 which sets the number of partials for each note generated.
 
#'''Duration:''' The tone's duration in seconds.
 
#'''Band Width:''' The noise band width in Hertz. Higher values result in a more noisy tone.
 
#'''Odd Harmonics Only:''' Choose between all harmonics or odd-numbered harmonics only.

{{external|[http://audacity.sourceforge.net/nyquist/klstrbas.ny View]}} |  {{external|[http://audacity.sourceforge.net/nyquist/klstrbas.zip Download]}}
 
 
 
 
 
Author: Steven Jones. KLSTRBAS (for "cluster bass") generates several signals with a fixed frequency ratio between them. Apparently, early Roland drum machines created cymbal sound in part by combining multiple square waves with non-integral frequency ratios. The combined signal was then high pass filtered to produce a very dense cluster of high frequency harmonics. The genesis of KLSTRBAS was a failed attempt to create cymbal sounds using this technique.
 
 
 
Parameters: 
 
 
 
#'''Key:''' MIDI key number
 
#'''Decay:''' Decay time in whole seconds
 
#'''Fdecay:''' Fractional decay time in 1/100 seconds
 
#'''Density:''' The number of component waveforms is four times the density. Higher densities produce a deeper flange effect but can also cause the sound to go out of tune.
 
#'''Detune:''' Affects relative frequencies. See below.
 
#'''Flange:''' Affects relative frequencies. See below
 
#'''Tab:''' Wave form used as a basic component. 0=sine, 1=tri, 2=square, 3=saw. The wave tables are not band limited so {{external|[http://en.wikipedia.org/wiki/Aliasing aliasing]}} may result if either key or n are too high.
 
 
 
The frequency of each component is determined by the key number, the detune and flange parameters. Specifically the nth component has a frequency of: <br>
 
p * (1 + d/100 + g)^n  <br>
 
where:<br>
 
p is the fundamental frequency determined by the key number,<br>
 
d is the detune amount 0 &lt;= d &lt;= 99, and <br>
 
g is derived by the flange parameter (g = 1/(10^(4-f)) for flange value f)
 
 
 
KLSTRBAS can also produce synth kick drum sounds by setting decay time to a fraction of a second.

Author: Steven Jones. Generates a modulated pulse tone.
 
 
 
Parameters:
 
 
 
#'''Key:''' Tones frequency as MIDI key number  [0...127] <br>
 
#'''Cents:''' Detune amount in cents [0...99]<br>
 
#'''Duration:''' Tones duration in milliseconds [1...30000]<br>
 
#'''Mod Rate:''' Number of modulation cycles [1...100]<br>
 
#'''Mod Depth:''' Modulation depth as percent [-100...+100]<br>
 
#'''Mod Wave:''' 0 = tri, 1 = up sawtooth, 2 = down sawtooth<br>
 
#'''Width:''' Fixed pulse width as percent [0...100]<br>
 
#'''Amp:''' Amplitude as percent [0...100]<br>
 
 
 
If the sum of the fixed width and the instantaneous modulation amount is outside the interval [0,99], the output will go to full off or full on.

Touch Tones (also known as DTMF or Dual Tone Multi Frequency Tones) are the tones made by key pads on telephones. Each tone is comprised of two separate tones at different pitch, hence "dual tone". 
 
 
 
Parameters:
 
 
 
#'''Number of DTMF Tones'''
 
#'''Option to include military tones A-D
 
#'''Option to include silent intervals
 
#'''Volume'''
 
#'''Tone length''' in seconds
 
#'''High to low tone ratio''' (or twist) in dB
 
#'''Post silence duration''' in milliseconds
 
 
 
"Twist" is the volume ratio between the higher-pitched and lower-pitched tones in any given tone. So a twist value of 0 dB means the higher-pitched tone is no louder than the lower-pitched tone. A twist value of 4 dB means the higher-pitched tone is 4 dB louder than the lower-pitched tone.

Author: Steven Jones. Algorithmic sequencer number 1. The sq1 sequencer generates complex sequences of tones by using the sum of three square-wave low frequency oscillators to frequency-modulate two oscillators. The oscillators output one of four waves (sine, tri, square and saw) and may be detuned relative to each other. The wave tables are not band-limited so aliasing will result for sufficiently high frequencies.  There is also an overall three-stage amplitude envelope.
 
 
 
Parameters:
 
 
 
#'''Center:''' The unmodulated carrier frequency in Hz
 
#'''Detune:''' The frequency of oscillator 2 relative to oscillator 1
 
#'''Wave:'''  The wave selector [0=sine, 1=tri, 2=square, 3=saw]. Both oscillators produce the same wave-shape.
 
#'''Attack:'''  Attack time in seconds
 
#'''Sustain:''' Sustain time in seconds
 
#'''Decay:''' Decay time in seconds
 
#'''f1:'''  Frequency of LFO 1
 
#'''a1:'''  Amplitude of LFO 1
 
#'''f2:'''  Frequency of LFO 2
 
#'''a2:'''  Amplitude of LFO 2
 
#'''f3:'''  Frequency of LFO 3
 
#'''a3:'''  Amplitude of LFO 3
 
 
 
The three LFOs are interchangeable. Note that the LFO amplitudes are calibrated in Hz indicating the corresponding frequency shift in the audio oscillators.

LFO Surf generator. A signal whose frequency is generally below the human ear's ability to hear as a tone, usually 20 cycles per second [Hz]. Generates mono or stereo surf which sweeps between a lower and upper filter frequency. Stereo surf also sweeps back-and-forth
 
somewhere between the left and right audio channels. To generate stereo surf, first open a new stereo track in Audacity. Do this by ALT, P, S in Audacity pre-1.3, or ALT, T, N, S in 1.3 and later. 
 
 
 
Parameters:
 
 
 
:1. '''Mono or stereo surf:''' [1=mono 2=stereo]
 
:Mono surf is heard only in the center between the two speakers, or in the middle of your head when wearing headphones. Stereo surf sweeps back-and-forth somewhere between the two audio channels, depending on the next setting, Stereo Spread.
 
 
 
:2. '''Stereo spread:''' [stereo only: percent]
 
:The larger this value, the more widely the stereo surf will move back-and-forth between the left and right audio channels. When this value is above zero, the deeper section of the surf sweep will be heard more in the left channel; below zero, the deeper section of the surf sweep will be heard more in the right channel.
 
 
 
:3. '''Fade-in and fade-out times:''' [seconds]
 
:To smoothly fade in and fade out the volume at the start and end of the surf.
 
 
 
:4. '''Surf duration:''' [minutes] (up to 60)
 
 
 
:5. '''Surf type:'''  [0=white noise 1=pink noise]
 
:White noise is more of a "hissing" sound, whereas pink noise is a lower "rushing" sound. Technically, white noise is "equal energy per frequency", whereas pink noise is "equal energy per octave"
 
 
 
:6. '''Surf sweep frequency:''' [Hz]
 
:Sets how slow or fast the surf sweeps between the lower and upper filter frequencies, and the left and right channels [for stereo surf].
 
 
 
:7. '''Lower filter frequency:''' [Hz]
 
:8. '''Upper filter frequency:''' [Hz]
 
:Both the above determine how low and how high the lowpass filter sweeps the surf noise.
 
 
 
:9. '''Bass frequency to boost:''' [Hz]
 
:You can boost the volume of frequencies of the surf sound below this setting, to get a deeper-sounding surf. Somewhat equivalent to the bass knob on your stereo.
 
 
 
:10. '''Bass boost :''' [dB]
 
:Sets how much to boost the above bass frequency. 0 dB means no boost, 6 dB means double the amplitude of the bass frequency, and so on.
 
 
 
 
 
'''Note:'''
 
 
 
If you get an error message "Nyquist returned too many audio channels", this means you tried to generate stereo surf without first having opened a blank stereo track in Audacity. See instructions at the start of this help file for instructions on how to do this.

Jean-Michel Jarre put out a hauntingly beautiful electronic album in 1976, Oxygene. One section of this album had a repeating surf sound: a sweep from the right to the left audio channel, a pause, and then a deep crash in the right channel. After another pause, this cycle repeated many times. Very relaxing to listen to. This sound generator plug-in emulates that surf cycle, in either mono or stereo.
 
 
 
Start a new session of Audacity. To generate stereo surf, first open a blank stereo track (ALT, P, S in Audacity pre-1.3, ALT, T, N, S in 1.3 and later). Open the generate menu. Click on "Surf [Oxygene]".
 
 
 
Parameters:
 
 
 
:1. '''Surf output:''' [1=mono 2=stereo]
 
:To generate mono or stereo Oxygene surf.
 
 
 
:2. '''Stereo spread:''' [stereo only - percent]
 
:If you've chosen to generate stereo Oxygene surf, this setting will determine how widely the surf sweeps away from the center pan position. From +100 percent to -100 percent. Positive values make the sweep section go from the right to the left, with the crash in the right. Negative values reverse this pattern.
 
 
 
:3. '''Fade-in and fade-out times:''' [seconds]
 
: Time to fade in and fade out the volume at the start and end of the surf, if you wish.
 
 
 
:4. '''Number of Oxygene surf cycles:'''
 
:How many Oxygene surf cycles to generate.
 
 
 
:5. '''Surf type:''' [0=white noise 1=pink noise]
 
:White noise is a higher-frequency "hissing", whereas pink noise is a lower-frequency "rushing" sound.
 
 
 
:6. '''Sweep starting filter frequency:''' [Hz]
 
:7. '''Sweep ending filter frequency:''' [Hz]
 
:The above two parameters set the starting and ending frequencies for the lowpass filter to sweep the sweep portion of Oxygene surf. A lowpass filter allows frequencies below a certain value to pass, while frequencies above that value are attenuated, or reduced in volume.
 
 
 
:8. '''Sweep duration:''' [seconds]
 
:This sets how slow or fast the sweep portion of Oxygene surf takes.
 
 
 
:9. '''Post-sweep silence duration:''' [seconds]
 
:Duration of the silence after the sweep.
 
 
 
:10. '''Crash filter frequency:''' [Hz]
 
:The lowpass filter frequency of the crash.
 
 
 
:11. '''Crash bass frequency boost:''' [dB]
 
:How much to increase the volume of the above filter frequency and below. 0 dB means no boost, 6 dB means double the amplitude of this bass frequency, and so on.
 
 
 
:12. '''Post-crash silence duration:''' [seconds]
 
:How much silence before the Oxygene surf cycle repeats.
 
 
 
 
 
'''Notes:'''
 
#If you get an error message "Nyquist returned too many audio channels", this means you tried to generate stereo surf without having first opened a blank stereo track in Audacity. See instructions at the top of this help file on how to do this.
 
#In the original Oxygene, reverb was applied to the surf, giving it a more expansive sound and feeling. If you want to have reverb added to Oxygene surf, you need to apply it yourself after the surf sound has been generated. There's "GVerb" already in the Audacity effects menu, and many people use Anwida's free VST reverb plug-in.

In preparing to do some vocal work with Audacity, I realized I wanted a software tuning fork. After you have copied tuningfork.ny into your Audacity plug-ins folder and restarted Audacity, Tuning Fork is in the generate menu. After you click on it, a brief table outlining C notes and their equivalent MIDI note numbers appears near the top of the screen. (C0=0 C1=12 C2=24 and so on).
 
 
 
Parameters:
 
 
 
:1. '''Tone duration:''' up to 120 seconds.
 
:2. '''Constant or fade out:''' (0=constant 1=fade out, default=0 constant)
 
:Choose whether you want the tone to remain at constant volume or fade out during the duration.
 
:3. '''MIDI or frequency:''' (0=MIDI 1=frequency, default=0 MIDI)
 
:Choose whether to generate a MIDI note number or frequency. Middle C=MIDI note 60, A440=MIDI note 69.
 
:4. '''MIDI note:'''
 
:If you have chosen to generate a MIDI note, enter the note number here. Note that you can use non-integers here (such as 60.75)

Combines the bouncing Ball Delay and Delay with Tone Shift plug-ins. A delay effect in which the echos get faster, like a bouncing ball. And each echo is shifted in pitch by the designated amount in semitone plus cents (hundredths of a semitone).
 
 
 
Parameters:
 
 
 
#'''Decay amount''' [dB]:
 
#'''Delay time''' [seconds]:
 
#'''Number of bounces''' [times]:
 
#'''Tone shift (whole)''' [semitones]:
 
#'''Tone shift (cents)''' [cents]:
 
 
 
'''Note:'''
 
The value for the decay amount (in db) for an increasing pitch can be left at the default 0. However, with decreasing pitch, the lengths of the delays increase over time, overlapping with each other more and more. In this case, clipping can occur if the decay value is left at 0.

* Center pan Remover (often called Vocal Remover)
 
 
 
For removing vocals which are panned to center, you can invert one
 
channel then pan both channels to center. Audio which is common to
 
both channels then disappears. this often removes other audio such
 
as drums, which are also often panned to center.
 
 
 
With centerpanremover.ny, you can select whether to invert one
 
channel, or to invert a range of frequencies in one channel, before
 
panning both channels to center.
 
 
 
Variables
 
 
 
1. Select whether to invert one channel or a band of frequencies.
 
2. If frequency band is selected, "remove frequencies above..." is default 500Hz.
 
3. If frequency band is selected, "remove frequencies below..." is default 2000Hz.
 
 
 
In other words, with the default settings, a two-octave range from
 
500Hz to 2000Hz (2 kilohertz) is removed.
 
 
 
Audio that isn't exactly panned to center is louder in one channel
 
than in the other. Thus, the further from the center pan position,
 
the louder that audio will be in the result.

* chimesdelay.ny: Chimes Delay
 
 
 
(Version 2 plug-in, works in Audacity 1.2.3 and later)
 
 
 
1. Adds random delay to your audio. You can specify the maximum
 
delay of the random delays (default 10 seconds, maximum 120
 
seconds) and how many random delays within that max delay time
 
(default 20 delays, maximum 100).
 
 
 
2. Using the minimum volume field, you can specify the lowest
 
random volume that each random delay can have (default is 50
 
percent, range between 0 and 100 percent).
 
 
 
3. This plug-in also randomly changes the pitch of each random
 
delay. You can specify a note list (which is where the name 'Chimes
 
Delay' comes from). the following is the default note list:
 
 
 
-24 -12 -5 0 4 7 12 14 19
 
 
 
Each number indicates how many semitones your audio could be pitch
 
shifted (along with matching tempo shift). For example, 0 indicates
 
no pitch shift, 12 indicates rise of 12 semitones (one octave), -5
 
indicates drop of 5 semitones (like going from C down to G below
 
that C note).
 
 
 
If the audio you have loaded into Audacity is C3, the above note
 
list would produce the following notes randomly:
 
 
 
C1 C2 G2 C3 E3 G3 C4 D4 G4
 
 
 
A distinctly major-sounding scale.
 
 
 
If you have a note list specified, this plug-in will randomly
 
choose from that list of notes for pitch and tempo shifting of each
 
random delay.
 
 
 
4. However, you can delete this note list, in which case a list of
 
notes will be generated between a lower and upper number. The
 
default values of these two numbers are -12 semitones (decrease of
 
1 octave) and +24 semitones (increase of 2 octaves), respectively.
 
 
 
5. If your audio is in stereo, each random delay with random volume
 
and random pitch change will also be randomly panned anywhere
 
between left and right. (It is best that your audio is first panned
 
to center before applying Chimes Delay.)
 
 
 
6. Additional notes:
 
Adding a bit of regular delay and/or other effects before applying
 
Chimes Delay results in a richer sound.
 
 
 
If you want a particular note (from the note list) to be repeated
 
more often, you can enter it more than once in the list.
 
 
 
If you simply want your audio randomly delayed with no multiple
 
pitch changes, either enter just one number into the note list, or
 
enter the same number into the min and max notes fields.
 
 
 
If you want no random amplitude changes, make the amplitude field
 
100 percent.
 
 
 
It is possible that total length of your resulting audio will be
 
max delay _plus_ duration of your original audio. This may be still
 
longer if the final delay(s) is/are decreased in pitch (resulting
 
in a reduced tempo).
 
 
 
If your original audio is non-musical, chimesdelay.ny will not make
 
it musical.
 
 
 
Many thanks to Steven Jones! - his cool 'Harmonic Noise' generator
 
plug-in is the source for Nyquist code to handle a string-input
 
note list. Thanks Steven for additional list help as well.

Example audio clips:  {{external|1=[http://audacity.sourceforge.net/nyquist/comb1.mp3 [MP3 Clip 1]]}}&nbsp;&nbsp; 
 
 
 
The name 'comb' filter comes from how it acts on the audio spectrum
 
of what it's applied to: it looks like a comb with the teeth
 
pointing up. For example, if you set the comb frequency at 1000 Hz,
 
the comb filter emphasizes 1000 Hz as well as 2000, 3000, 4000 and
 
so on Hz. This particular plug-in produces an 'airy' effect, which
 
is more pronounced the higher the comb decay value is set, and
 
resonance is increasingly produced as well.
 
 
 
A comb filter can be produced using flanger-like settings on a
 
delay effect, but this filter does not use a delay to get the
 
result, so it does sound somewhat different.

Dual Tape Decks effect
 
 
 
This plug-in was written to duplicate an effect I heard in the late
 
1970s: I recorded then played identical audio on two mono tape
 
decks. There was an amazing "whooshing" effect as one tape deck
 
"caught up" with and passed what the other tape deck was playing.
 
This plug-in allows the "whooshing" to go back and forth. Different
 
effects are made using mono-sounding vs. "true" stereo audio.
 
 
 
You can adjust the phase difference between the two decks (180
 
degrees is the default), the starting phase of the effect (0
 
degrees is the default), LFO frequency and depth of the effect. The
 
larger depth is, the more pronounced the pitch and tempo shift
 
become until there is a noticeable warble.
 
 
 
Neat stereo flanger-like effects can be made by (for example)
 
applying dualtapedecks.ny to audio, applying Stereo Butterfly (static)
 
with a spread value of zero (sounds mono after applying), then
 
applying dualtapedecks.ny a second time with the same settings as the
 
first time.
 
 
 
This plug-in will work on mono audio as well, but the only effect
 
will be rising and falling changes in pitch and tempo.

Once copied into your Audacity plug-ins folder, this plug-in
 
utility appears in the analyze menu. It gives the duration of audio
 
you have selected. A lot easier to use for people using a screen
 
reader (rather than trying to decipher those numbers on the
 
screen).
 
 
 
If you have opened or imported more than one track and have not yet
 
done a Quick Mix, this plug-in sequentially gives the duration of
 
each track you loaded into Audacity. Simply press &lt;enter&gt;
 
after each track duration is given. The final screen gives
 
information from Nyquist, which you can ignore. Simply press
 
&lt;enter&gt; to get to the regular Audacity screen.
 
 
 
This is a Nyquist Version 2 plug-in which works in Audacity 1.2.3
 
and later.

equalabl.ny: Regular interval labels [analyze menu plug-in]
 
 
 
thanks to Sami Jumppanen from the Audacity users group for
 
suggesting this plug-in: adding labels to the label track at
 
regular intervals. Thanks to leland Lucius from the Audacity
 
development list for code feedback which helped wake me from late
 
night programming! And thanks to Gale Andrews from the Audacity
 
development list for suggesting improvements.
 
 
 
<i>Warning! Using this plug-in will delete any label track you had
 
in your loaded audio. If you accidentally use this plug-in and want
 
to restore your previous label track, simply press control+z
 
once.</i>
 
 
 
After you've copied equalabl.ny into your Audacity plug-ins folder,
 
start a new session of audacity. Load audio you want to add
 
regularly-spaced labels to. Select audio [control+a]. Open analyze
 
menu [alt+a]. Click on 'Regular interval labels'. use or change the
 
following five default variablees:
 
 
 
1. Label interval [seconds]: Default sixty seconds between labels, from one second to six
 
hundred seconds [ten minutes].
 
 
 
2. Label text: The text that will appear in each label, default is "label".
 
 
 
3. Prepend numbers to label text [0=no 1=yes]: Default is yes, so your labels would sequentially be "0label 1label..." and so on, using the default text.
 
 
 
4. Final label [0=exclude 1=include]<br>
 
 
 
For example, if your selection is sixty seconds long, and your
 
label interval is ten seconds, the final label would be at the
 
exact end of your selection. By default, the above variable is to
 
exclude [not set] the final label.
 
 
 
5. Final audio segment duration equal with others [0=no 1=yes] <br>
 
Your label interval setting may result in the final segment of
 
audio being unequal with the preceding ones. By default, the above
 
variable is set to make the final audio segment equal in duration
 
with the preceding ones. This might make the label interval
 
slightly different from your chosen one, depending on the size of
 
the final audio segment.
 
 
 
<i>Note</i>
 
 
 
People using a screen reader can view the label track in Audacity
 
1.3.3 beta by opening the track menu [alt+t] and clicking on 'edit
 
labels'. The labels and their time positions can be read by
 
cursoring up and down and left-right. press alt+f4 to return to the
 
main Audacity screen.
 
 
 
released to the Audacity community  June 25, 2007.
 
 
 
Thanks to Alex S. Brown for example code from his silencemarker.ny
 
plug-in for placing labels on the label track.<br>

* Extract Audio (percent)
 
 
 
Select all your audio, then use this plug-in to set the start and
 
end margins using percentages. Start and end margins are anywhere
 
from 0 to 100 percent.
 
 
 
If for example your audio is ten seconds long, you set the start at
 
0 percent and the end at 50 percent, the result will be the first
 
5 seconds of your selected audio. If you re-apply the effect with
 
the same settings, the result will be the first 2.5 seconds of your
 
original selected audio.
 
 
 
If you do not like the extracted audio margins, you can undo the
 
result and apply with slightly different settings. Or you can re-
 
apply for shrinking the audio further. Great for people who do not
 
want to fiddle around with the cursor keys for selecting audio.
 
 
 
Beware! Audio outside the start and end percent margins will be
 
discarded! A plug-in for re-inserting the (altered) extracted audio
 
into the discarded audio is in the works.

* Delay with Stereo Flip
 
 
 
This is a stereo delay effect: with each delay, the stereo channels
 
are flipped left-right and vice versa. Inspired by a sound effect
 
heard in the opening track of Mike Oldfield's "songs From Distant
 
Earth."
 
 
 
Variables:
 
 
 
decay: the drop in volume (db) with each delay (default 3.0);
 
 
 
delay time: default 0.5 seconds;
 
 
 
number of delays, including the original audio: default 10.
 
 
 
Thanks to Steven Jones for illustrating how to check for even/odd
 
numbers.

the default value is 0 db),  number of delays, the starting cutoff
 
frequency of the high pass filter, and how much to increase the

The hyperexp effect is a type of compression. Signal amplitudes of approximately

Notch filter
 
 
 
 
 
 
 
Like its name suggests, a notch filter cuts out a "notch" in the
 
 
 
spectrum of your audio. The default frequency is 60Hz, great for
 
 
 
removing 60Hz electrical hum, in case your recording equipment has
 
 
 
picked this up.
 
 
 
 
 
 
 
The second control, q, determines the width of the notch cut from
 
 
 
your audio. Default q is 1, below 1 creates a wider notch, above 1
 
 
 
creates a narrower notch.

* Delay with Pitch Shift
 
 
 
 
 
 
 
A delay plug-in except each delay is pitch shifted. Standard delay
 
 
 
variables: decay (in db), delay time (in seconds), and number of
 
 
 
delays. Also includes amount of pitch shift (from 0.1 to 10.0) and
 
 
 
selection of whether the pitch is to be multiplied (0) or divided
 
 
 
(1) by the shift number.
 
 
 
 
 
 
 
* tonedelay.ny: Delay with Tone Shift
 
 
 
 
 
 
 
Similar to pitchshift.ny except you can define in semitones how
 
 
 
much each delay is to be pitch shifted. A shift of 1 semitone means
 
 
 
each delay is increased in pitch by 1 semitone, a shift of -1 means
 
 
 
a decrease of 1 semitone. Includes whole semitones plus semitone
 
 
 
cents (hundredths of a semitone).
 
 
 
 
 
 
 
Warning! Both plug-ins are best applied to relatively short
 
 
 
duration audio, or few number of delays for longer audio. Otherwise
 
 
 
Audacity will be working a _long_ time. Same thing seems to happen
 
 
 
if there is already pitch shifting within the audio. (This all may
 
 
 
be simply my computer, which runs at 233MHz.)

Modulation, there are maxspeed and factor controls, plus a third
 
 
 
control, the maximum cutoff frequency of the low pass filter.
 
 
 
 
 
 
 
Once again, the lower you set maxspeed, the higher you must set
 
 
 
factor to get similar depth of random filtering result. You can use
 
 
 
factor to decrease or increase the amount of randomness modulation.

Random pitch Modulation
 
 
 
 
 
 
 
Randomly modulates the pitch of your audio. As with previous
 
 
 
randomly-controlled effects, the maximum speed (maxspeed) of the
 
 
 
random changes is adjustable (in Hz). Again, the lower maxspeed is,
 
 
 
the higher you must set the factor control to get the same depth of
 
 
 
randomness as with higher maxspeed settings.
 
 
 
 
 
 
 
Increasing warping depth gives you increasing pitch changes. A
 
 
 
fourth control, max pitch depth, is included. If the warping depth
 
 
 
is high enough, max depth should be made higher otherwise there
 
 
 
will be momentary periods of no pitch changes. With lower warping
 
 
 
settings, this does not happen, and the effect can be re-applied
 
 
 
repeatedly for further random pitch changes.
 
 
 
 
 
 
 
It's difficult to explain the workings of the controls, it's easier
 
 
 
to experiment and find out what happens.
 
 
 
 
 
 
 
This effect works on mono and stereo audio. In stereo, each channel
 
 
 
has different random pitch modulation applied.

* sequencer1b.ny: Audio Sample Sequencer 1.b
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Improved over sequencer 1.a: simplified code makes this a version
 
 
 
 
 
 
 
1 plug-in. Sequences mono and stereo audio already loaded into
 
 
 
 
 
 
 
Audacity, whether a note, vocal sound, series of notes and/or vocal
 
 
 
 
 
 
 
sounds, etc. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Select all audio first, then click on Audio Sample Sequencer 1.b
 
 
 
 
 
 
 
from the effects menu.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Variables:
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
tempo (steady, in beats per minute);
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
beats per measure (one to sixteen). This plug-in "assumes" that one
 
 
 
 
 
 
 
sequence of notes is one measure;
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
sequences to generate: how many of these sequences do you want to
 
 
 
 
 
 
 
generate (from one to a thousand);
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
16 pairs of tone shift and volume level (tone shift is measured in
 
 
 
 
 
 
 
semitones - 0 means no tone shift, negative numbers indicate tone
 
 
 
 
 
 
 
drop, positive numbers indicate tone increase; volume level 1.0
 
 
 
 
 
 
 
means regular volume, 0.0 means you do not hear a note generated
 
 
 
 
 
 
 
for that beat. volume can range from 0.0 to 1.0.)
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
When you have a tone loaded into Audacity, you can create a major
 
 
 
 
 
 
 
scale of 8 notes by 1. selecting desired tempo; 2. selecting 8
 
 
 
 
 
 
 
beats per measure; 3. selecting how many sets
 
 
 
 
 
 
 
(sequences) of these 8 notes you want to generate (default is 16).
 
 
 
 
 
 
 
These would be the settings for the 8 tone shift edit fields:
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
0, 2, 4, 5, 7, 9, 11, 12.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If you start with a C note, the above settings will generate a C
 
 
 
 
 
 
 
major scale. If your starting note is a B flat note, the above will
 
 
 
 
 
 
 
create a B flat major scale.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Rhythms can also be created by playing with the volume edit fields.
 
 
 
 
 
 
 
For example, in a series of eighth notes, notes which fall on only
 
 
 
 
 
 
 
the first, fourth and seventh beats can be made by making beats per
 
 
 
 
 
 
 
measure 8, and making volume on #2, 3, 5, 6 and 8 to 0.0.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
It is possible to generate a short sequence using this plug-in,
 
 
 
 
 
 
 
then apply it again to that new audio with different settings.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Copy sequencer1b.ny into your Audacity plug-ins folder. The next
 
 
 
 
 
 
 
time you open Audacity, you'll find audio Sample Sequencer 1.b in
 
 
 
 
 
 
 
the effects menu.

* Tempo Change
 
 
 
 
 
 
 
I want to convert old tapes recorded at half speed to normal speed
 
 
 
using Audacity, and  wanted a simple plug-in to change tempo.
 
 
 
 
 
 
 
Variables
 
 
 
 
 
 
 
1. Tempo change: default is 0.5.<br>
 
 
 
2. Multiply or divide selector: 0=multiply, 1=divide; default is 0.
 
 
 
 
 
 
 
If multiply is selected, tempo of the audio is multiplied by the
 
 
 
tempo change number. Selecting divide divides the tempo by the
 
 
 
tempo change number.
 
 
 
 
 
 
 
Applying this effect to selected audio (using default settings)
 
 
 
halves the tempo (and therefore the pitch).
 
 
 
 
 
 
 
Multiplying by 0.5 is the same as dividing by 2.
 
 
 
 
 
 
 
Audio examples
 
 
 
 
 
 
 
tempo1.mp3: "Hello" at half, normal and twice normal speeds.

* Time Shift Tool
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
A plug-in for performing the same task as the time shift tool in
 
 
 
 
 
 
 
Audacity.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Choose the track you want to time shift (0=left, 1=right), and the
 
 
 
 
 
 
 
amount to shift (range from 0.0 to 100.0 milliseconds). If you
 
 
 
 
 
 
 
choose the left channel shifted by 10.0ms, it will start 10.0ms
 
 
 
 
 
 
 
later than previously.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Only works on stereo audio. Useful for aligning tracks due to
 
 
 
 
 
 
 
recording latency. Also can be used for stereo effects.

(version 2 plug-in)
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Improved over the previous turntablewarp.ny plug-in - you can warp
 
 
 
 
 
 
 
both mono and stereo audio.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
You can simulate unplugging your turntable while it's playing,
 
 
 
 
 
 
 
plugging it in, and related effects. A version 2 Nyquist plug-in
 
 
 
 
 
 
 
which works on Audacity 1.2.3 and later.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Variables with explanations:
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
"step" indicates how many semitones above or below pitch of
 
 
 
 
 
 
 
original audio (1 step = 1 semitone, 12 steps = 1 octave, etc.);
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
"amplitude" indicates volume level (in percent).
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
There are 5 values you can change:
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
1. start step (default 0): how many semitones above or below
 
 
 
 
 
 
 
original audio at start of selection;
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
2. start amplitude (default 100%): volume at start of selection;
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
3. change time (default 50%): point in time of original selection
 
 
 
 
 
 
 
at which warping values can change between first and second part of
 
 
 
 
 
 
 
selection. This point has an internal step value of 0 semitones
 
 
 
 
 
 
 
change, and internal volume of 100%;
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
4. end step (default -12 semitones, 1 octave drop): at end of
 
 
 
 
 
 
 
warped selection, how many semitones audio has been warped;
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
5. end volume (default 40%): volume at end of warped audio.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Applying this plug-in with the default settings results in the
 
 
 
 
 
 
 
audio starting to slow down halfway through the original selection,
 
 
 
 
 
 
 
and dropping to 40% of original volume. Like unplugging a turntable
 
 
 
 
 
 
 
while it's playing.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Since the "change time" is internally set at step 0 semitones and
 
 
 
 
 
 
 
volume 100%, different warping effects can be created, depending on
 
 
 
 
 
 
 
the start and end step and volume values:
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
slowing down then speeding up;<br>
 
 
 
 
 
 
 
speeding up then slowing down;<br>
 
 
 
 
 
 
 
speeding up to a particular step value then remaining at that
 
 
 
 
 
 
 
value;<br>
 
 
 
 
 
 
 
slowly speeding up then quickly speeding up;<br>
 
 
 
 
 
 
 
etc.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Thanks to Roger B. Dannenberg for the warp tutorial on which this
 
 
 
 
 
 
 
plug-in is based. Thanks Sebastien Chopin for the request for the
 
 
 
 
 
 
 
stereo version of this plug-in.

Revision as of 13:40, 20 June 2021

This page lists all Nyquist plug-ins for Audacity that are available as separate downloads. Nyquist plug-ins support Windows, Mac and Linux/Unix. Click any "Downloads" link to jump to the downloads page for that plug-in category.
Unless otherwise indicated, all plug-ins are released under the terms of the GNU General Public License, version 2.

Downloading or viewing plug-ins

Download:

  • Left-click the download link to download the file in almost all web browsers. If this only displays the plug-in code, right-click the download link and select "Save Link As...", Save As..." or some similar "Save" or "Download" command. For further information, please see the documentation for your web browser.

View the plug-in code:

  • Chrome: Download any plug-in once, then right-click over the download button at the bottom of the browser and choose "Always open this file type".
  • Firefox: Open Options or Preferences, then click the "General" section at the top. In the "Downloads" section, choose "Always ask me where to save files". When you click the download link, you now have an extra option to open the file in a chosen application instead of save it.
  • Internet Explorer or Microsoft Edge: Right-click the download link, choose any of the "Open" options then in the box that appears, click the "Open" button. In Edge, this also downloads the file.
  • Safari: Downloaded plug-ins will automatically open in your default text editor after download. You can disable automatic open after download in Safari Preferences.


Installing plug-ins

To install Nyquist plug-ins in Audacity, follow the instructions in the Audacity manual:


Compatibility

These plug-ins were contributed over many years, and many versions of Audacity. In the vast majority of cases, old plug-ins should continue to work in more recent versions of Audacity. More recent Nyquist effects may not install in old versions of Audacity or may not work correctly.

Warning icon It is highly recommended to use the latest release version of Audacity, which is available via the Audacity website.

List of available plug-ins

Warning icon Feedback and bug reports:
  • All new plug-ins added to this list are tested in the Audacity version current at the time, but many of the older plug-ins are still in need of testing.
    • Please report any bugs to the Nyquist section of the Audacity forum so they may be fixed.
    • Some Nyquist plug-ins are unsuitable for processing long audio tracks. If a plug-in causes excessive memory use and causes Audacity to freeze or crash when used on long tracks, please let us know so that we can either limit the plug-in to short selections or add a note to the plug-in description so as to warn other users of the possibility.
  • Please also let us know which plug-ins you like and find useful as that will help us to develop the types of plug-ins that users want.
