Free plug-ins to add new features and effects to Audacity.
A “peak limiter” is a kind of dynamic range compression effect that “pushes down” on peaks so as to reduce their level. Unlike other compressor effects, limiters have little or no effect on the surrounding audio (except for a few milliseconds either side of the peak). They are particularly useful for reducing “transients” (very short loud … Continue reading Peak Limiter
Audacity includes a wide range of built-in effects, but surprisingly there is no distortion effect. Time to remedy that… Here is a simple distortion effect with 10 types of distortion.

For anyone unfamiliar with the term (as I was), Isochronic beats are related to binaural and monaural beats and the idea of brainwave entrainment. At … Continue reading Isochronic Modulator Plug-in
