Standard Plug-in Pack

These are the same Nyquist plug-ins that are presently available in current Audacity. You will probably not need to download this pack unless you have inadvertently deleted one or more of the standard Nyquist plug-ins from your Audacity installation.

Legacy Generate Plug-ins

Noise Band

(nseband.ny) View | Download | Type 1 Plug-in

Author: Steven Jones.

Noise Band creates narrow band noise by ring-modulating a sine wave with low-pass filtered noise. The effect is similar to band-pass filtering noise.

Parameters:

  1. Center Frequency: [10 - 10000 Hz, default 10]
  2. Band Width: [1 - 10000 Hz, default 50]
  3. Duration: [0 - 30 seconds, default 1]
  4. Fractional Duration: [0 - 00 hundredths of a second, default 0]



Risset Drum (v1)

(risset.ny) View | Download | Type 1 plug-in

Author: Steven Jones.

Simulates a drum sound, based on the work of Jean Claude Risset.

Parameters:

  1. Frequency: [50 2000 Hz, default 100]
  2. Decay: [0.125 - 10 seconds, default 2]
  3. Noise center frequency: [100 - 5000 Hz, default 500]
  4. Noise band width: [10 - 1000 Hz, default 400]
  5. Noise mix: [0 - 100 percent, default 50]



Random Touch Tones

(pwm.ny) View | Download | Example audio clip | Type 1 plug-in

Author: David R.Sky

Generates Random Touch-Tones. This is a similar effect to DTMF Tones (random)

Parameters:

  1. Number of Touch Tones: [1 - 1000, default 10]
  2. Tone duration: [0.001 - 1.000, default 0.05]
  3. High to low tone ratio: [0.0 - 4.0, default 4.0]
  4. Post silence duration: [0.0 - 1.0, default 0.05]

Bass Boost

(bassboost.ny) View | Download |

Author: Steve Daulton, after Nasca Octavian Paul

This is a Nyquist version of the C++ Bass Boost as shipped in Audacity up to version 2.0.2. Unlike the C++ version, the version downloadable here does not clip audio which has an output above 0 dB. Therefore if you use default 32-bit float format for audio tracks, audio that is boosted above the clipping level of 0 dB can be brought back down below 0 dB without damage by using Effect > Amplify.

Parameters:

  1. Filter Frequency (Hz): [0 to 1000 Hz, default 200]
  2. Boost by (dB): [0 to 36 dB, default 12]



Turntable Warping (v2)

(*bug)

(turntablewarp.ny) View | Download

Authors: David R.Sky

Based on "warp" tutorial by Roger B. Dannenberg. Simulates unplugging and plugging in a turntable while it's powered, and related effects such as speeding it up before unplugging it.

Parameters:

  1. Initial step: [-36 - +36 semitones, default 0] - the resulting pitch change at the start of the selection, defined as number of semitones above or below the original pitch (1 step = 1 semitone, so 12 steps = 1 octave.)
  2. Initial amplitude: [0 - 100 percent, default 100] - the resulting volume at the start of the selection, related to the original amplitude (so 100% = no change).
  3. Change time: [0 - 100 percent, default 50] - the point in time in the selection at which the warping values moves away from the original value. Depending on the start and end step and amplitude values, you can design warps that slow down then speed up; speed up then slow down; speed up to a particular pitch then remain there; slowly speed up then quickly speed up.
  4. End step: [-36 - +36 semitones, default -12] - the resulting pitch change at the end of the audio. compared to the original pitch.
  5. End amplitude: [0 - 100 percent, default 40] - the resulting volume at the end of the selection, compared to the original volume.

Steps are number of semitones above or below non-warped audio.
