This page provides tips on how to use Audacity's built-in effects. A full list of the built-in effects in Audacity 1.2.6 is here .
HINT: To use effects you must first of all select the audio you want to apply the effect to, and stop playback or recording.

For help in selecting tracks or areas of audio, see Selecting Audio.

Help with specific effects

  • Click Removal - using Audacity's Click Removal, Draw Tool and other solutions
  • GVerb - also alternative reverberation plug-ins: Anwida and Freeverb
  • High Pass Filter - attenuates frequencies below a limit that you set, allowing through (passing) those above the limit. Can be used to reduce low frequency noise.
  • Low Pass Filter - attenuates frequencies above a limit that you set, allowing through (passing) those below the limit. Can be used to reduce high pitched noise.
  • Noise Removal - using Audacity's Noise Removal Effect and other solutions for removing steady noise

Using external macro program to acess effects

A user wanted to one-click access to effects he used frequently - ideally through a popup menu.

I suggested this could be done on Windows with macro programs such as AutoHotKey  (open source), PowerPro  (freeware) and other paid-for Macro programs (eg. RoboTask). Googling Macro+MAC+OS+X turns up such programs as QuickKeys  (paid-for), Keyboard Maestro, Key Xing and Youpi Key (caveat: I have no Mac experience). Another possible solution is Apple's UI Scripting  (requires user to have detailed UI knowledge), which problem can be overcome with the UIBrowser Assistant .

That's the theory - in practice I haven't yet been able to create a script that will do the job. I'm pursuing this, initially with AutoHotKey and will update this when I have a working example. --Alec Burgess 16:24, 29 September 2007 (PDT)
