* '''Automatic segmentation during Record:''' {{votes|10}} Automatically segments the audio being recorded into another track upon meeting the user defined settings for  "silence" length, threshold level and number of track to be split.

{{devcomment|The best way to do this might be to add labels at the track splits, which fits in with other requests to label points where Sound Activated Recording pauses when the audio falls below the specified threshold.}}

* '''Beat Finder Improvements''':

** See "BPM Detection" in [[#Highest-rated|Highest-rated]]  

** Search for periodicities, let user refine and add time measures, then redo with probability/interpolation bases on added information. Use the corrected beats and a dynamics analysis to detect musical structures like verse, refrain. See [[Beat Finder Improvements]] for details.

** '''Create regions encompassing each beat''' by inputting a BPM (maybe include auto-dedection of the BPM), see [http://hdimage.org/images/csgys65npvbd6dpqaz9h.png image]. The region can then be moved, duplicated etc. as normal to create loops or re-mixes easily.

<ul>{{devcomment|This could be quite a powerful idea when Audacity supports multiple label selection, [[#paste|Paste Special]] and/or [[GSoC Ideas 2008#Intuitive cross-fading|intuitive crossfade]].}}</ul> 

* '''Clips:'''

** '''Allow left-click in track to snap to or retain split line not delete it:''' {{votes|12}} For example, right-click to remove the split-line, as is done to remove the cut line.

* '''Snap to editing cursor''' and show Boundary Snap Guide {{votes|2}}  

<div id="labels"></div>

* '''Labels:'''

** '''Multi-Label-Select:''' Ability to select multiple (not necessarily adjacent) labels (such as with control-click or shift-click) {{votesdate|11|23May18}}

*** Should work on point labels, too, thereby selecting regions between labels. {{votes|5}}  

*** '''Play Labels Only:''' Play clipped in or labelled regions only - standard feature on professional audio editing systems. skipping the non-selected regions.  This feature would be useful for comparing two regions of an audio file without delay between their playback.{{votes|5}}  

*** '''Change font size/color for selected text in labels''' {{votesdate|7|02Nov17}}

*** '''Multiple select must work in Edit Labels too''' {{votes|1}}  

** '''Invert labels:''' {{votes|2}} Replace current labels with new labels that start from the end of the previous label to the start of the next label. If two of the original labels touch (but don't overlap), they will be replaced with a point label at the point where they meet.

** '''Snap labels to:'''

***'''Other labels''' {{votes|11}}

***'''Editing cursor''' {{votes|7}}

***'''Clips''' {{votes|5}}

***'''Selection boundary''' {{votes|3}}

** '''Mark-in and mark-out points''':  As per video editors, "I" sets Edit In Point and "O" sets Edit Out Point. Should use zero-crossing accuracy. Doesn't matter what you do between those two actions; once you press "O", everything between "I" and "O" is selected. {{votes|12}} 

** '''Easy way to select a region between labels''' {{votes|9}}

<ul>{{devcomment|Would the interface changes required be worth it when there is an easy solution now? Click where you want to "mark in" (can be in an existing point-label) and hold SHIFT while clicking where you want to "mark out"; a region is drawn between the click points. Currently, the SHIFT-click can't be in a label, it has to be in the waveform, but shift-clicking between labels could be added. Also see [[NavigationTips#Marking cut regions or points|Marking cut regions or points]].}}

<ul><li> '''Moving a label draws original and current edge(s) in waveform''' without having to select the label {{votes|7}}

<li> '''Right-click functionality:''' {{votes|3}}

<li> '''Add label''' {{votes|2}} </ul>

<li> '''Moving a label moves the audio:''' {{votes|2}}  

<li> {{done}} '''More distinction between region and point labels when zoomed out:''' {{votes|4}} so that Export Multiple does not produce a few milliseconds of audio if you accidentally drag a point label when zoomed in.</ul>

{{devcomment|There already is the distinction that zoomed out and selected, the minimal region label will show no vertical line in the waveform and a double arrowhead in the Timeline, versus vertical line and single arrowhead for a point label. Still, it seems a reasonable addition for a point label to have a different-colored vertical line in label track and waveform.}}

<ul><li> '''Labels include metadata''' {{votes|6}} - not a request for cue sheet support, instead this gives a way in compilation albums to pass other than track Title and Track Number to Metadata Editor

<li>'''Automatic label text during playback/recording:''' {{votes|3}} When using Add Label at Playback Position, provide an option to populate labels automatically with pre-defined text then close the label. Provide an option to increment the entered numbers or letters. 

<li> '''Import label by simply drag-and-drop label file''' {{votes|1}} </ul></ul>

<ul><ul><li>'''Expand-to-silence:''' {{votes|2}} expand selection command expands the selection leftwards and rightwards until silence between songs or beginning/end of track is found  </ul></ul>

<ul><ul><li>'''Expand-to-non-silence:''' {{votes|3}} Double-click any point in a "silence" to automatically select the complete silence - useful for voice editing. </ul></ul>

<ul>{{devcomment|In Audacity 2.x, Analyze > Silence Finder labels silence, and Effect > Truncate Silence can remove these silences.}}</ul>

<ul><ul><li> '''Minimum distance between labels''' {{votes|6}} similar to Nero Wave Editor it can be very handy when handling large amount of spoken audio</ul>

{{devcomment|1=There is an experimental modification to Silence Finder [https://forum.audacityteam.org/download/file.php?id=1545 here]}}

<ul><li> '''Count the number of silences''' produced to cross-check with number of tracks on an LP or cassette {{votes|1}} </ul>

<ul><li> '''Unified Silence Finder and Sound Finder:''' {{votes|4}} Discussed many times before but never resolved. See https://forum.audacityteam.org/viewtopic.php?p=212445#p212445.

<ul><li> '''Parameters must be saved''' so that it launches in last used Sound or Silence mode  {{votes|2}} </ul></ul>

<ul><li> '''New Label Track name defaults to Current Track name''' {{votesdate|1|30Mar17}} When a new label track is created then its name should default to that of the currently selected (audio?) track to which the labels relate.  The currently selected track is the most likely to be relevant to the label track.  If there are multiple unnamed Audio Tracks, then it doesn't matter what name the label track defaults to since, if the name is of any concern anyway, then it will need to be renamed anyway. It is just as easy to rename it from 'Audio Track' as it is to rename it from 'Label Track' - both are equally un-useful. </ul>

{{devcomment|If there is more than one audio track, it may not be obvious which to choose for the label name. If all the audio tracks are called the default "Audio Track" then Label Track should not be called "Audio Track".}}</ul>

** '''Move Cursor Too!''' Cursor within the track being moved should move with the track, not stay at same time point. {{votes|1}} Additionally, if this cursor extended over other visible tracks, it would make it much easier to line up one track with the others. <ul>{{devcomment|You can extend the cursor through all tracks by holding down SHIFT then clicking in the [https://web.audacityteam.org/onlinehelp-1.2/menu_track.htm Track Control Panels] of the other tracks.}}</ul>

<ul><ul><li>'''Allow overlapping clips''' as in CoolEdit, but give overlap a different color {{votes|1}}

<li> '''Lock-beyond:''' {{votes|2}} Set a lock point beyond which tracks cannot be dragged. Could be set in current direction of travel or by right-click menu. '''Use Case:''' Set maximum length in a project with many overlapping tracks where you may not be able to see the end (bottom) of the project.

<li> '''An individual track locking capability''' to prevent inadvertent time shifting or changes to previously edited tracks

<li> '''Allow shifting by less than distance between samples'''  {{votes|1}}  

*'''Split to multiple projects:''' Split the project into smaller multiple projects by labels, similar to the "Export Multiple" command. Each project retains the per-track labels of the original single project. {{votes|10}}

** '''Save selection as new project:''' {{votes|3}}

== Frequency Analysis Capabilities ==

{{Hint|There are many additional single-vote suggestions at [[Suggested Frequency Analysis Capabilities]]. If any there especially appeal to you, please cut and paste them below and include your own vote for them.}}

<div id="rtplot"></div>

* '''Real time plot when playing audio:''' {{votesdate|13|07Mar17}} Or, in view of the CPU demands of calculating the spectrum, have Audacity do plot spectrum at given time intervals. {{devcomment|Plotting spectrum while recording would likely be impractical due to the risk of errors writing the recording data.}}

* '''Zoomable/pannable sliders''' {{votes|13}}  

** '''Absolute minimum dB could still be set by Meter/Waveform dB Preference''', but use slider to set minimum within that. {{votes|1}}

* '''Normalization presets''' {{votes|10}} Understandable default called e.g. "music" that gives a result like 1.2 plot, so that a section with most samples close to 0 dB peaks near to 0 dB in the spectrum, not at -20 dB

* '''Exported plot file should have metadata:''' {{votes|5}} giving current plot window settings and a timestamp.  

** Should also include path to project file {{votes|1}}

** '''Preference or option for analyzable length:''' {{votes|1}}  

* '''Exported file should identify each peak and cursor position''' {{votes|3}}

* '''Remember window height/width across sessions''' {{votes|5}}

* '''Alternative plot from cursor point:''' {{votes|2}} like CoolEdit, without having to select a region. Audacity could internally select the region length/position.

{{devcomment| Audacity 2.x by default selects "all" on no selection, so an exception would have to be allowed for Plot Spectrum. Also, region selection must still be offered for those analyzing a specific note.}}

* '''Plot cepstrum, energy, etc. offline:''' {{votes|1}} Plot cepstrum and other indicators at given time intervals.

* '''Linear option for vertical dB scale:''' {{votes|4}} Use cases:

** Demonstrating  primary resonances of different instruments to elementary physics of music students without room noise and other musically insignificant peaks becoming over-prominent

** Shows power in peaks as directly proportional to height.  

* '''Make Plot Spectrum "WINDOW" a real window:''' The problem:

**Switching between one screen and another is a pain because:

**# The Spectrum Window is always on top of the main window

**# It can not be reduced in size below a fairly large size

**# The Spectrum Window does not appear on the Desktop Task Bar

** Ideally I would like.

**# The Spectrum window to be a real window (with a minimize button)

**# To be able to resize the window like other windows (with scroll bars when reduced below the minimum size)

**# To see the Spectrum Window on the Desktop Task Bar

**# A tick box on the Spectrum Window for "always on top"

<ul><ul>

<li>'''Import text file containing amplitude data for each sample''' {{votes|2}}

<li> '''RMS data wanted not just peak values''' {{votes|1}}

<li> '''Allow selection by seconds as well as samples''' {{votes|1}}  

 

* '''Track sample data:''' headroom to dBFS (audio level), peak minimum and maximum sample, RMS volume, replay gain etc. see SF, Wavelab, Cool Edit etc. over an arbitrary length of audio, even the whole file. {{votes|8}}

<ul>{{devcomment|This could work well with the new Vamp analysis plug-ins/}}</ul>

 

* '''Find Clicks''' producing labels like "Find Clipping", possibly using sine-wave-curve-fit prediction algorithm and labelling where waveform diverges from prediction. {{votes|2}}

* '''Pitch Accuracy Analysis:''' add votes [[#pitch_accuracy|below]].

* '''Oscilloscope:''' {{votes|1}} showing audio signal(s) converted to voltages over time.

* '''Frequency band splitter:''' I find this feature in Fscape (an xplatform app similar to Soundhack) http://www.sciss.de/fscape/ -  to be very useful and would like to see it or a Nyquist script written to do something similar: a panel would appear when Band Splitting function is selected and would allow the user to

#define bands as freq/bandwidth -or- crossover freqs

# processes the bands or crossover parameters on a soundfile or a selection of a soundfile

# output these as separate files into a selected directory -- similar to splitting soundfiles according to label regions

{{Hint|1=There is a separate [[Automation]] page for detailed discussions about new or advanced methods of workflow automation. For example we are at an early stage of developing the ability to drive Windows versions of Audacity from a perl or other [https://manual.audacityteam.org/man/scripting.html script] via a named pipe. At this stage this feature is suitable for developers only, but you can request the feature by voting below.}}

<div id="scripting"></div>

* {{done}} '''Make Scripting (mod-script-pipe) available after enabling it in Preferences, without having to compile Audacity and the scripting module''' {{votesdate|26|19Mar17}}   

** Normalization/levelling and/or cropping of many files/tracks {{votes|5}}  

** Noise removal and other built-in filters or effects {{votes|5}}  

** Create many audio clips from many different audio files {{votes|4}}  

** preconfigure exports to a particular format {{votes|4}}

** Repetitive use of effects at different parameters {{votes|2}}

** apply Macros without use of mouse

** for audio analysis

** export files and their label track   

** using information from online music databases such as Discogs

 

 

<div id="pedal"></div>

* '''Control Audacity by a foot pedal''' {{votes|25}} attached to the game, serial or USB port so that hands are free for transcription work. Also useful for non-transcription applications, such as recording off a commercial two-way radio with a squelch output signal.

<div id="cls"></div>

* {{done}}{{todo}} Control Audacity from command line {{votes|33}}

{{devcomment|1=See [http://sox.sourceforge.net SoX] for am alternative command line solution.}}

* {{done}} '''Include features dependent on selecting regions''' (e.g. trim, fades) {{votes|51}}

{{devcomment|This is partly supported in Audacity 2.0.1 or later by adding to the chain/Macro appropriate [[Download Nyquist Plug-ins|Nyquist plug-ins]] that operate on selections.<br>

This is fully supported in Audacity 2.3.0 or later which has 'scriptables' for manipulating the current selection.}}  

* {{todo}} '''Additional Export format options:'''

** '''Export FFmpeg formats''' {{votesdate|52|04May17}}  

** '''Export sample rate''' {{votesdate|39|22Jul17}} This is important for MP3 and other compressed formats because if a file imported for batch processing switches the project rate to something not supported by the export format, the batch comes to a halt at the resample dialog. Alternatively have a preference to OK the resample dialog automatically at the offered setting. This would not however alter the project rate, which is a separate suggested command

** '''Export format parameters''' {{votesdate|33|04Apr17}} like bit rate, as in the Options button in the file export window. Parameters for Macro-ed and norrmal exports should be stored separately.  

** '''Export Other uncompressed''' {{votesdate|28|21Feb17}}  

** '''Export 24/32-bit WAV''' {{votesdate|2|22Jul17}}

** '''Export AIFF''' {{votes|2}}

* {{done}} '''Apply Macros to multiple projects''' {{votesdate|23|14Feb19}} instead of giving error messages

* {{todo}} Include '''Export Multiple''' {{votesdate|21|22May18}} with options into Macro commands

* {{done}}{{todo}} '''Support Generate / Analyze effects''' {{votes|15}} both those built into Audacity and user-added ones in any other formats supported by Macros

{{devcomment|1=Some but not all are done for 2.3.0 Macros -but probably not all are suitable}}

* {{todo}} '''Recursive selection of all files in one or more directories:''' {{votesdate|14|19Aug19}}

* {{todo}} '''Export directory''' {{votes|10}}

{{devcomment|1=Planned for 2.3.0}}

* {{todo}} '''Export Labels''' {{votes|1}}

* {{done}} Support Silence Finder {{votes|5}}

{{devcomment|1=Done for 2.3.0 Macros''}}

* '''Vamp support''' {{votes|2}}

* '''Split Stereo Track:'''  

* {{done}} '''Single Macros dialog from which you can edit and apply the Macro''' {{votes|6}} 

* '''Example parameters:''' {{votes|1}} EX 1: (Reduce 4 dB at 2000 Hz with Q shelve 8 dB per Octave). EX 2: De-esser fx ( threshold= -24  above 3800 Hz )

** but no beep for individual dialogs in a Macro) {{votes|2}} See https://forum.audacityteam.org/viewtopic.php?p=213546#p213546.

* {{done}} '''Import / Export buttons:''' so users can share Macros more easily {{votes|3}}

* '''Ability to recover Macros applied to files if they crash''' {{votes|1}}

* '''Wider Apply Macro dialog''' so you can see file names with long paths {{votes|2}}

* '''Apply Macro dialog should be interactive:''' so you can scroll the list vertically or horizontally {{votes|1}}

* '''Include arbitrary Shortcut Key commands''' e.g. CTRL + SHIFT + D to Macros array so that it can auto-task menu-dropdown and other manual mouse-click functions without disrupting batch automation. {{votes|1}}

* '''Separately pick the mp3 settings''' in the Macros feature

*'''Allow Macros to continue after failure:''' Allow Macros to optionally continue processing the next file after processing a file fails. Currently, when a batch process encounters a problem with one of the files in its list of files-to-process, the entire batch process aborts. For unattended operations this can be inconvenient.

**'''Peter:''' for detailed discussion see this archived Forum thread: https://forum.audacityteam.org/viewtopic.php?f=20&t=88413

<div id="macro"></div>

* {{done}}{{todo}}'''Support Edit and navigation commands''' {{votesdate|2|23Jul17}} such as paste, duplicate, add new track, move focus to next / previous track, move cursor to selection start / selection end / track start / 

{{devcomment|1=Some are in for 2.3.0: Paste, Duplicate and Move Focus - in 2.4.x all are in except "Add New Track"}}

* {{done}} '''Support Transport commands''' {{votesdate|2|23Jul17}} An example suggested by / for language learners: record 2 seconds then play what has been recorded.

* '''Create macro by recording a sequence of actions''' {{votesdate|2|23Jul17}} Example: The record macro feature in CoolEdit Pro.

{{devcomment|This could be implemented by recording key strokes, possibly with an option to also record mouse events.}}

=== Fader Automation === 

* '''Adjust the Mixer Board or Track Control Panel gain sliders while playing then record the slider moves''' so you can render them if desired. {{votes|4}}. Common feature on many other multi-track audio applications. In this way one can build up a mix, adjusting individual tracks and tweaking levels until just right. This would first require changing to linear envelope points.  Could be extended to panning (if we had a pan envelope).

<div id="transcription"></div>

== Better transcription support ==

* '''Label Tracks more suitable for transcription:'''  {{votes|10}}

** multi-line labels {{votes|4}}

** '''Second search method for text in labels other than using [[#labels_editor|Labels Editor]]:'''  {{votesdate|1|26May17}} - this would just be Find Next and Previous with a Replace option. A found occurrence of the text would move focus to the label that has the requested text and highlight that text within the label. Provide option to search in current label track only or in other label tracks.

<ul>{{devcomment|Create 30 second tone, zoom out until it half fills screen then type in a label. When label is full, can't add more characters unless you zoom in (zooming allows you to scroll). [[User:James|James]]: If/when we improve transcription we want to support multi-line text and linking with a true text editor.}}</ul>

* '''real time loop editing:''' the fact that Audacity has partial functionality in making loops i.e. allow you to select and play a loop but NOT adjust the loop points in real time seems to me a half baked implementation of loop editing.  Please - if you are going to allow someone to select and play a loop then go ALL the way and also allow them to edit it in real time?

*'''Faster Play-at-Speed:''' Currently the transcription toolbar function PlayAtSpeed has a maximum value of 3X. My editing deck allows much higher multiples, I am used to searching raw data for "non-music" (speech etc.) and can recognize the difference at speeds between 7X and 10X.

* Allow '''[[RealTimeAdjustment|real-time effects]]''' {{votes|166}}

<!-- The first two requests below should total to the same as the root vote for real-time effects-->

** <font color="gray"><strike>'''Real-time effect preview sufficient as a first step''' {{votes|102}}</strike></font> ''this is now in current Audacity''

*** Allow disabling real-time for a selected track as in REAPER.{{votes|5}}

** Stomp box/guitar effects: {{votes|3}} - one of the most useful features of Diamond Cut 7.

*'''Save a Noise Reduction Profile:''' save and manage a Noise Reduction Profile for future use in subsequent projects

* '''BPM and beat timecode automatic detection and beat matching''' {{votes|66}}

* '''Vinyl-specific noise removal effects''' such as low level rapid tickiness, groove rasping... (like GramoFile or other specialist [[Audio Restoration|tools]] ) {{votes|12}}

* '''Built-in Expander''' (which is often coupled with a noise gate) {{votes|14}}    

** Compressor could include expander function {{votes|1}}

** Presets such as for dbx/HighCom {{votes|1}}

* '''Filters:'''

** Bandpass {{votes|3}}

* '''DirectX effects''' not just VST {{votesdate|7|28Jan19}}

<ul><li>'''Pitch correction''' after setting to required key (like Auto-Tune), including T-Pain forced pitch effect {{votes|13}} </ul>

<ul><li>'''Pitch accuracy analysis:''' {{votes|1}} Could be a Nyquist effect that shows the average pitch with cents deviation of labeled notes, or average pitch then on a further run adds a waveform representation of the labeled audio showing pitch deviation over time. See: https://forum.audacityteam.org/viewtopic.php?f=42&t=73796.

<ul><li>'''Better as another View Mode accessed from Track Control Panel instead:''' {{votes|1}}</ul></ul>

* '''Room Panning:''' Pan different tracks to different parts of a room for surround sound effect.{{votes|4}}

* '''Channel Mixer (built-in):''' {{votes|1}}  Similar to the Nyquist [https://wiki.audacityteam.org/wiki/Nyquist_Effect_Plug-ins#Channel_Mixer Channel Mixer] but built-in with real-time preview, which would be particularly useful when using the effect for widening or narrowing the stereo field.

** '''Stereo widener''' {{votes|2}}  

{{devcomment|Available in the [https://wiki.audacityteam.org/wiki/Nyquist_Effect_Plug-ins#Channel_Mixer Channel Mixer] plug-in, but see above.}}

* '''Stereo effect from mono''' {{votes|3}}

{{devcomment|Available in the [https://wiki.audacityteam.org/wiki/Nyquist_Effect_plug-ins#Pseudo-Stereo Pseudo-Stereo] plug-in.}}

* '''Smoothen effect''', perhaps using a weighted average (or a better method){{votes|1}}

**I  wonder about a tool to easy removing of noise could be useful in the application. Like the rubber tool in f.ex. photoshop.  The rubber tool should flatten the noise when you touch the noise. It would then be possible to remove noise with less zooming. And maybe it could be useful to have the possibility to set the pencil to (f.ex. with SHIFT ) only go complete horizontally.

* '''Specialised Voice effects:'''

:* '''Advanced formant tools:''' {{votes|6}} Professional pitch change/tune while retaining the formants, so retaining the characteristics of the original voice

:* '''Text to speech:''' Possibly by implementing [http://espeak.sourceforge.net/ eSpeak] in Audacity {{votesdate|1|26Sep17}}

* '''Dolby B/Dolby C filters''' for converting to/from tape recordings in Dolby) {{votes|4}}

**<I> Will need quite a lot of trial and error by ear, as the Dolby process is recording level dependent. Needs expander and treble cut.</I>

**<I> I agree. It would be tricky to get it right without straight-up copying the actual process.  This would be a licensing no-no. Trust me, I work at Dolby.</I>

** <I>There is a Winamp plug-in which simulates Dolby decoding [http://www.hansvanzutphen.com/tape_restore_live/ here]. </I>

* '''Exciter''' to enhance album or tape recordings. It is actually an easy effect and only needs a high pass and distortion. This is widespread use in recording studios and radio stations.

{{devcomment|There are definitely some entries in the Forum for this - I will count votes later}}

* '''Deverb/Echo Cancellation:''' Echo Removal Tool/Deverb slider. This could improve back-of-the-room recordings. Sliders are "Liveness," "Room Size," "Room Oblongedness," and "Dirt" (same as sliders in an Echo Generator). {{votes|8}} {{devcomment|Deverb is exceptionally difficult and virtually unknown in audio software except [http://www.hydrogenaudio.org/forums/lofiversion/index.php/t22051.html Postfish].}}<ul><ul><li>Can't both deverb and echo cancellation be implemented by convolving the signal with a modified version of the room's impulse response?</ul></ul><ul><ul><li>No, those operations can't be performed by convolution, this is the case where '''deconvolution''' (aka inverse convolution) has to be used (well, not always).</ul></ul>

* '''De-essing''' {{votes|5}}

* '''Re-essing:'''   This is to improve the sound of already low bandwidth voice recordings by adding higher frequencies.

* '''Multiply two frequencies''' multiply waveforms together as in AM radio

** Convolution is built into the Nyquist language and is an incredibly powerful feature. If I understand correctly, one could take a simple click, perform any combination of filter/chorus/echo/reverb/equalization/etc. on it, and then apply this pre-calculated set of effects to a long signal. Why wasn't this added long ago, along with multiplying and adding signals? [http://en.wikipedia.org/wiki/Convolution#Fast_convolution_algorithms Implementing convolution]

* '''Chorus:''' {{votesdate|10|17Feb17}}

** '''Only needs rate and depth controls''' {{votes|8}}

** '''Multi-voice Chorus''' {{votes|1}}

* '''Chop with segments of silence:'''  

* '''Suppress quiet signals'''.  A squelch level suppression to squelch out signals below a adjustable preset level.  (originally this was in the recording enhancements section - but it's better as an effect.).

* '''EQ Matching:''' {{votes|4}}  SmartEQ function to sample the frequency spectrum of a given piece of audio with a pleasing equalisation, then bring a second piece of audio to the same spectral content. Useful for most cassette recordings and other other medium- and low-fidelity sources. Also usable for sfx. Note: where frequency content falls to the noise floor, this may increase noise level heavily in an attempt to compensate. This is easily addressed afterwards with the Noise Removal, or can be addressed during frequency correction with more coding. Possibly could be incorporated as a third radio button in the current 1.3.x equaliser, with a "Get Frequency Profile" button and ability to add useful profiles as a custom preset.

**You could sample another waveform (in another track) at regular time intervals, and the instantaneous level of the sample determines the frequency of a tone generated for the same interval of time. In the real-world Arp 2600, you could patch the output of a VCO (or other audio source) into the input of the S&H module, then patch the S&H output into the control voltage input jack of another VCO. In the Audacity version, the user makes a selection in the track to be sampled (analogous to the first VCO) , and then (in a dialog box) selects the time interval between samples, the minimum and maximum frequency to be generated. The duration of the resulting sequence of tones to be generated in a new track would be the same as the duration of the original selection. Optional - select sine, sawtooth, square, or triangle waveforms for the generated tone. Another option would be to be able to sub-divide the length of the selection into X number of sample intervals, as opposed to specifying the duration of the interval. Typical results would be a sequence of discrete pseudo-random (frequency) tones at regular intervals, like a retro movie sound effect for a computer that's busy thinking. Another example: Sampling a triangle waveform whose period is much longer than the sample interval would result in a series of ascending and descending stepped tones.

* '''Reduce Formant / Boost the fundamental frequency of a signal''' - replace a vocal or instrument signal with the sine wave or square wave of the fundamental frequency of that signal. Would help identify notes through overly distorted or overlayered signals. [https://forum.audacityteam.org/viewtopic.php?f=12&t=12901 forum post] {{votes|1}}

*'''Transfer Function Effect in time domain:''' {{votes|1}} Drawn with mouse, with presets and import/export.

{{devcomment|[[Nyquist]] has arguably more powerful functionality, but not graphical. So many rules could apply in any one case that the transferability would be very limited and case-specific.}}

<ul><li>'''[https://en.wikipedia.org/wiki/Flanging Flanger]:''' Classic effect, not the [https://wiki.audacityteam.org/wiki/Nyquist_Effect_Plug-ins#Flanger_.28linear.29 linear flanger plugin]. {{votesdate|1|17Feb17}}</ul>

* '''Effects Categorization:''' Allow the effects dropdown menu capable of sub-folders or categorisation so that the user can organize his plug-ins however he wishes. {{votes|49}}

<div id="favorites"></div>

** '''Only two levels deep:''' (Effects > Category), not 3 levels as tried before (Effects > Category > Sub Category). Sub categories are just too fiddly and too much clicking. With just one level of categories, the menu will open by hovering the mouse, making locating a specific effect much quicker and easier. {{votes|7}}

** '''Detect/display subfolders of the "Plug-Ins" folder as categories:''' {{votes|6}} So if you have a folder called /Plug-Ins/MyEffects/ the menu shows Effects > MyEffects > (effects in the MyEffects folder).

** '''Must include VST plug-ins in system folders''' {{votes|4}}

* '''Manipulate effects with a dialog box''' that has all plug-ins on the left hand side, an empty box on the right hand side, with "New Group...", "Delete Group", "Rename Group", "OK", "Cancel" buttons below, and arrows ">>" and "<<" in the middle, to move plug-ins between groups. {{votes|2}}

: {{devcomment|1.3.6 Beta had incomplete categorization of Nyquist and LADSPA plug-ins. Categorisation has a penalty in more difficult navigation, and was withdrawn from 1.3.7 until there is (at least) a way to turn it on and off.}}

* '''General (Effect menu items):'''

** '''Plug-ins can have different number of input and output tracks:''' for example surround encoder in the [http://plugin.org.uk/ plugin.org] package needs four inputs but produces two outputs.  {{votes|1}}

:* '''Curve Editor''' for each effect to adjust how ferociously the effect changes the sample by time (posted on behalf of nitrotrigger on [[Irc|IRC]]) {{votes|3}}

:* '''On-Demand effects:''' {{votes|2}} Effects apply while you continue to work (hear them applied in one part of the track by clicking there) 

:* '''Defaults:'''

::*{{done}} '''"Defaults" button'''  {{votes|4}}

:*Very strong opinions to consider [[GVerb#Freeverb3|Freeverb3]] as the "best" benchmark/starting point for reverb types and features (but don't include the whole suite as is) {{votes|14}}

:*sensible presets that do not depend on mixing with a duplicate to sound decent {{votes|6}}

:*stereo output.{{votes|4}}

{{devcomment|1=The [http://www.youtube.com/watch?v=rjYYzNsNqlY&feature=youtu.be Harrison implementation] looks like an example of how to implement GVerb well, but that depends at a minimum on Audacity supporting real-time effects.}} 

* '''Amplify:'''

** '''Toggle non-destructive clipping''' when in 32-bit float quality {{votes|1}}

** '''Option to launch at last used amplification level:''' {{votes|5}} even if the New Peak Amplitude is different each time. Use case is trying/undoing different amplification amounts to get the one you want, and you want to see quickly what you last tried (or do it again if you think that will give you the desired result. 

** '''Default to last used maximum dB level:''' {{votes|1}} Currently it defaults to 0 dB whereas Normalize defaults to last used maximum.  

* '''Bass and Treble:'''

** '''Reinstate Bass Boost effect or add Frequency control to Bass and Treble:''' {{votes|7}}

:** '''Change Speed presets to/from 16 RPM''' {{votes|1}}</ul>  

** '''Detection for clicks that are of similar level to surrounding audio'''  or generally more reliable detection {{votes|28}}. [https://manual.audacityteam.org/o/man/click_removal.html Click Removal] gives hints for other solutions, but one tool should do the job in most cases, as with other software.

** '''Intelligent joining to boundaries''' {{votes|1}} like Repair so that doesn't potentially add artefacts by almost silencing the samples it replaces so leaving abrupt joins with the unchanged audio

<div id="compressor"></div>

* '''Compressor:'''

** '''Multi-band:''' {{votes|8}} so retaining the same frequency distribution.

*** '''Include a de-esser in this:''' {{votes|1}}  

** '''Process stereo pairs together:''' {{votes|7}} so that the same amount of gain reduction is applied to both channels. The current Compressor applies different gain reduction to each channel which can lead to shifting of stereo image.

** '''Shorter attack/release times:''' {{votes|5}}

*** '''Show attack/release times in milliseconds:''' {{votes|1}}

** '''Text box input:''' {{votes|5}}

** '''Configurable lookahead in milliseconds:''' {{votes|4}} so pre-emptively apply the compression. Don't just make it the same as the Attack Time as now. 

** '''Choose upward or downwards compression independent of peak or RMS envelope:''' {{votes|2}}

** '''Choose make-up gain amount''' {{votes|2}}

** '''Built-in Hard limiter/dual slope/tabbed for different settings''' {{votes|2}}

** '''Presets for common tasks:''' {{votes|2}} such as "Levelling speech", "Maximizing", "Audiobook compression", "Peak limiting". Eliminates the need to install third party compressor plug-ins for casual users. 

** '''Finer Ratio discrimination than .5:''' {{votes|1}}  

** '''Envelope-based''' tool that just works by dragging as in Digital Performer {{votes|1}}  

<div id="eq"></div>

<div id="78curves"></div>

:* '''De-emphasis for early CDs:''' {{votes|2}} using the WaveEmph or other curves (see  http://www.hydrogenaudio.org/forums/index.php?showtopic=65067 )

:*** Edit box like Label Editor that would list all the points and allow normal editing functions like copy and paste {{votes|1}}

:** '''Zoomable grids''' {{votes|5}}

:* '''[[Graphic Equalizer - simple|Simpler/more presettable Graphic EQ]]:''' {{votes|3}} Either an alternative interface with current EQ, or an additional built-in effect. 5 - 7 bands would be adequate/quicker for our many casual users. Greater range of general purpose presets needed such as "heavy bass boost", "light treble reduction", "equal loudness"....  These should be separated from other e.g. gramophone presets.

:* '''Graphic EQ sliders should allow choice of bandwidth''' {{votes|1}}

:* '''Separate built-in Parametric EQ''' {{votes|3}} i.e. where all parameters controlling the tone change have their own control.

:* '''Add built-in envelope''' so that amount of EQ (% of gain specified in parameters) can be varied over time  {{votes|1}}

:* '''Mini-waveform''' {{votes|2}} (time against amplitude) in which you can click to preview - see [http://www.nch.com.au/wavepad/masters.html Wavepad]

:* '''Save Presets without renaming "unnamed"''' {{votes|4}}  

:* '''More frequency-specific presets''' like "Very Bright", "Mid-range", "Classical", "Hard Rock", "Soft Rock", "Dr Dre" {{votes|3}}     

:* '''User-saved presets should save filter length and Draw/Graphic mode''' {{votes|1}} e.g. a curve with low frequency control points will require maximum length to be reasonably accurate but this length will slow down processing of other curves un-necessarily.

:* '''Remember window size and position''' {{votes|3}}  

:* '''FFT Filter''' seems to be missing in 1.3.3 (and in 1.3.5)  

:* '''Auto Complete Equalizer Graph:'''  I created a simple equalizer graph to get somebody out of trouble recently. I think it was a lot more bother than it needed to be.  Here's an illustration of an Adobe Photoshop tool.  See:  http://audacityteam.org/wiki/index.php?title=Image:Curves2.jpg  Note that there's only one new data point on the right-hand brightness curve, and yet Photoshop automatically produced a graceful, gentle, useful curve typical of a picture whose natural lighting had actually changed. It did not produce two straight lines and depend on me to painstakingly calculate the new points and put the rest of the curve in by hand.  I want the equalizer work window to run like that.

:**SteveTF responds:  Since Audacity does not currently support graphical interfaces for effects (which rules out the "CoolEdit Pro FFT filter" type GUI), could this be done using a bunch of sliders?

* '''Generate:'''

<!-- ** '''All generators should remember their parameters across sessions.''' {{votes|5}} Currently only DTMF and Noise do so, stored in audacity.cfg FIXED -->

** '''Provide way to default selection format to other than seconds.''' Either store the format in .cfg or let it default to the current Selection Toolbar format {{votesdate|36|09Aug17}}

** '''List notes for tone generation:''' {{votes|4}} e.g.middle C (264 Hz) etc.

** '''Applause''' {{votes|1}}  

** (2.x) '''Text box input''' as in 1.2, because much simpler to overtype irrespective of the format, and allows copy and paste {{votes|8}}  

** '''Choice of overtones to include:''' (within the limitations of the waveform chosen) {{votes|1}}.

* '''Generate follows Recording Channels:'''  Generate should give me stereo tone if Recording Channels is set to stereo in Device Toolbar {{votes|1}}.

** '''Modeless window:''' {{votes|5}} like Analyze > Contrast that lets you modify the selection with the window open. Clicking "Get Noise Profile" could then grab the profile but leave the window open while you select the audio to be noise-removed.

** '''Presets (including user-addable)''' such as "light hiss", "60Hz hum" {{votes|2}}

** '''Leave Only Noise''' option as in Adobe Audition. When user performs  this on a duplicated track which is then inverted and mixed with the original, it allows noise to be removed by pure cancel-by-inversion.

** '''Implement as a plug-in''' DX or VST, so people could use it in other applications. To filter noise out of mic input in real time, for example {{votes|1}}

** '''Better noise removal without fiddling with sliders:''' {{votes|2}}
