Free plug-ins to add new features and effects to Audacity.
This is an experimental “proof of concept” plug-in for FM encoding and decoding. It was written as a bit of fun for the Audacity community – a competition in September 2016 for Audacity users, developers and support crew. The plugin can be download here: Installation Instructions: For the current version of Audacity, please see HERE … Continue reading FM Encoder Decoder
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. Each preset modifies the shape of the waveform in its own particular way. There is also a slider control to set the amount, or “drive”. … Continue reading Distortion Effect
This little plug-in is a bit of fun. It is a distortion plug-in effect that simulates a kazoo. To use it, record yourself humming, then apply the effect. Some interesting sounds can be made by applying the effect to other sounds, such as guitar or keyboard recordings. Right click to save kazoo.ny (For Internet Explorer … Continue reading Kazoo Effect
This was one of my first attempts at modifying a Nyquist plug-in (so please don’t expect good coding style 🙂 Someone asked me about how to fix some badly clipped audio. Repairing clipped audio is bad enough at any time, but in this case the problem was exacerbated because not only were some of the … Continue reading Clipfix mod

This plug-in is based on the same code as the Variable Tremolo plug-in and was written in response to a request for a plug-in for making Isochronic Tones (Isochronic Beats). 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
This plug-in allows the left and right channels of stereo tracks to be mixed and distributed between the channels of a stereo track. Examples: Mix left and right channels in equal proportion to produce a 2 channel mono track. Invert left or right channel independently of the other. Mix each channel with the other channel … Continue reading Channel Mixer Plug-in
Well it turned out to be more of a challenge than anticipated, but finally it’s here. A Nyquist plug-in that allows envelopes to be created via text entry. This plug-in is basically complete, but requires a bit of tidying of the code. This is a version 3 plug-in and requires Audacity 1.3.x New features in … Continue reading Text Envelope 0.8 beta
Sometimes it is desirable to filter out a narrow frequency, but the usual notch filter (notch2 s Hz Q) is just too deep. The idea of this filter is to provide the narrow band of a notch filter, but to limit the depth of the notch by mixing in a proportion of the unfiltered audio. … Continue reading Depth limited notch filter
