{{Introrel|Audacity's '''[http://manual.audacityteam.org/o/man/compressor.html Compressor]''' effect reduces "dynamic range" by making the loud sections quieter, then optionally amplifies the compressed audio to be as loud as possible without clipping. This increases the perceived overall loudness of the audio.||[[EffectsTips|Effects Tips]]}}

* '''Chris's dynamic compressor''' by the late Chris Capel is a popular [http://en.wikipedia.org/wiki/Nyquist_%28programming_language%29 Nyquist] plug-in that tries to even out abrupt changes of volume by employing "''lookahead''" (this attempts to anticipate volume changes by starting to apply compression before the volume rises to the threshold level). There are options to soften the softer audio and invert loudness. See instructions for [[Nyquist Plug-ins#Installation|Nyquist plug-in installation]]. Several versions of this plug-in may be downloaded.
