MSP Dynamics Tutorial 1: Envelope Following

In this group of tutorials, we\’ll look at different ways to work with dynamics in audio signals. The ability to use and control the amplitude of an audio waveform is important for many applications, from the macro level (audio compression) to the micro level (distortion). In this first tutorial, we\’ll learn to derive control values from amplitude parameters of an audio signal which we can use to control parameters elsewhere in the signal chain. This technique is called envelope following.
