Audacity envelopes provide a useful, non-destructive way to modify the volume of the audio, but are rather fiddly to use. Due to the lack of numeric input, it’s virtually impossible to set precise values manually. This plug-in provides a simple way to add envelope control points with precise values. Download Installation: Installation is in the … Continue reading Envelope Control Points
Introduction “Assertions” (or simply “Asserts” are commonly used in many programming languages to help developers read and understand code, and to help to detect possible defects (bugs). An assert is usually a predicate that tests a variable in the program and returns a boolean (true / false) value. In common English, it is like saying: … Continue reading Assertions
Audacity has a “Change Speed” effect, but it is only accurate to three decimal places. For greater accuracy a short Nyquist script can be used in the Nyquist Prompt effect. In this example the length of the selected audio was 599.999 seconds and I wanted to stretch it to 600 seconds duration.The durations may be … Continue reading Changing the speed and length very accurately
It is a common misconception that Audacity’s Nyquist plug-ins must be slow because they are written in an interpreted programming Language. Nyquist is an interpreted language, meaning that it runs directly from the code rather than being compiled first, but the inner loops of many DSP functions are pre-compiled in highly optimised compiled C code. … Continue reading Are Nyquist Plug-ins slow? (Compiled vs Interpreted languages)
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 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
