Effect Menu - Audacity Development Manual. Audacity includes many built- in effects and also lets you use a wide range of plug- in effects. You can download many free plug- ins for Audacity from our website. Plug- ins always appear underneath the divider in the Effect menu. Released builds of Audacity include sample Nyquist and/or LADSPA effects. Add / Remove Plug- ins.. Selecting this option from the Effect Menu (or the Generate Menu or Analyze Menu) takes you to a dialog which enables you to load and unload Effects (and Generators and Analyzers) from Audacity.
This allows you to listen to how the first six seconds (by default) of the selected audio would sound if you pressed OK to apply the effect. The preview length can be changed on the Playback tab of Preferences.
All selected tracks are previewed irrespective of whether the tracks are muted or soloed. This is because the effect is applied to the selected audio. If Preview does not sound quite as you want, adjust the controls of the effect and Preview again. Built- in effects support saving of user presets but do not yet support real- time preview or import/export of presets from/to other machines. Increases or decreases the volume of the audio you have selected. Typically used to make a music track softer whenever speech in a commentary track is heard.
Click Removal is designed to remove clicks on audio tracks and is especially suited to declicking recordings made from vinyl records. It will usually work best on very short clicks. For broader individual pops in selections up to 1. Hz project rate), you could try the Repair effect. The default . The alternative . Make- up gain can be applied to either method, making the result as loud as possible without clipping, but not changing the dynamic range further.
By distorting the waveform the frequency content is changed, which will often make the sound . The result of waveshaping is equivalent to applying non- linear amplification to the audio waveform. Preset shaping functions are provided, each of which produces a different type of distortion. The delay time between each repeat is fixed, with no pause in between each repeat.
For a more configurable echo effect with a variable delay time and pitch- changed echoes, see Delay.. Adjusts the volume levels of particular frequencies. The shape of the fade is linear. The rapidity of the fade- in depends entirely on the length of the selection it is applied to. The shape of the fade is linear.
The rapidity of the fade- out depends entirely on the length of the selection it is applied to. This normally does not affect the sound of the audio at all. It is occasionally useful for vocal removal.
Nyquist is a applicationming language for producing and processing audio. For more information see Nyquist Plug- ins Reference. This may be useful for synthesizer pad sounds, identifying performance glitches or just creating interesting aural textures. Use Change Tempo or Sliding Time Scale rather than Paulstretch for tasks like slowing down a song to a . Don't use with faded audio.
They are also used to provide some of Audacity's built- in audio generators and analysis tools. A wide range of additional Nyquist effect, generation and analysis plug- ins can be obtained from Download Nyquist Plug- ins on our Wiki. You can also create fades to and from other than silence or full volume.
An example of this might be a fade in from 2. Limiting is a type of dynamic range compression.
Mastering engineers often use limiting combined with make- up gain to increase the perceived loudness of an audio recording during the audio mastering process. This is a good way to reduce mains hum or a whistle confined to a specific frequency with minimal damage to the remainder of the audio.

The same as the tremolo effect familiar to guitar and keyboard players. Vocals are often (but not always) recorded in this way. The classic method achieves this by subtracting one channel from the other, but the result will be (dual) mono (this method can be found under the Actions menu in this effect as . Vocals are often (but not always) recorded in this way. Vocals (or other audio) can only be removed with this plug- in when panned to center, in other words sounding equally loud in both left and right channels. Help text is available from within the effect's dialog box.
Vocoding a normal voice with white noise as provided in the effect will produce a robot- like voice for special effects. New Homes Terra Vista Round Rock Tx here. Other carriers can be used for subtly different voices. Vocoder can only be applied to unsplit stereo tracks. Most LADSPA plug- ins are effects, but they are also used to provide some of Audacity's built- in audio generators and can be used for audio analysis. Additional LADSPA plug- ins can be downloaded for Windows, Mac and Linux. They do not support import/export of presets but do support saving presets for use in Audacity only.
A few LADSPA plug- ins have an . When you change the options in this dialog, the changes apply only to the current effect that's open. All other LADSPA effects will remain at the default options shown below until you change their options. Compensation may not work in all cases, and for it to work, any compensation or latency reporting settings in the effect itself must be enabled. If compensation fails or if this Audacity setting is unchecked, effects that buffer audio will insert silence at the start of the processed selection and remove a corresponding amount of audio from the end of the selection.
Enabling or disabling compensation is effective immediately. They do not support import/export of presets but do support saving presets for use in Audacity only. Most LV2 effects that have a graphical interface will show that interface by default in Audacity.
Some LV2 effects do not allow directly embedding their interface into our effect dialog, so those effects will only show a textual interface in Audacity. Some LV2 effects require features that are not yet supported in Audacity, so display an error message when applying the effect. LV2 is a more advanced evolution of the LADSPA plug- in architecture.
Note that LV2 effects in Audacity cannot yet display a full graphical interface. VST instruments are not supported. VST effects are not supported on Windows or Mac even on 6. Conversely on Linux 6. VST's are supported. On Mac, the easiest folder to put the plug- in's VST file in is ~/Library/Application Support/audacity/Plug- Ins.
Then use to enable the VST effects and load them into Audacity, For details see Manage Effects. If an exported preset file is empty, the effect probably does not support presets and Audacity will not be able to import the saved presets. To save the current effect settings as a User Preset, select Save As.. Presets for VST effects are exported to a file. A presets file lets you move settings for a particular effect between computers on any operating platform that supports that effect.
Select Export.. This is the least flexible choice, mainly useful for the small number of effects that do not support FXP presets. Most other VST host applications do not support XML, so you may only be able to share XML presets between other computers running Audacity. It allows you to save the currently visible settings. The saved preset can then be loaded by the same effect running in Audacity or most other VST host applications, on any computer or operating platform it supports. Similarly FXP presets saved by a given effect in any VST host on any computer can be loaded into that effect in Audacity. Similarly an FXB bank saved by a given effect in any VST host on any computer can be loaded into that effect in Audacity.
By default presets are saved to the same location as the audacity.
