I wrote this crate [1] as a compressor in Rust which is the opposite of a noise gate, as in gain reduction is applied after a threshold is passed instead of gain reduction applied if it is under a threshold. If you want a really great approach to noise gating, a fixed threshold is fine but it works better when you apply it to the difference of two envelope followers - one with a short attack, long release (tracks input) and long attack, short release (tracks noise floor). Takes a bit to set it up, but it's a stupid simple way to get extremely effective gating and is easy to fine tune for your application. A lot of Voice Activity Detection (VAD) works this way; it's just a matter of tuning the coefficients and thresholds for your input. Also useful reference for envelope following are the DAFX text [2], Will Pirkle's textbook on audio in C++ [3] and Zölzer's text [4] [1] https://github.com/m-hilgendorf/rusty-compressor https://github.com/m-hilgendorf/rusty-compressor [2] https://www.amazon.com/DAFX-Digital-Effects-Udo-Z%C3%B6lzer/dp/0470665998 https://www.amazon.com/DAFX-Digital-Effects-Udo-Z%C3%B6lzer/...
