A C++ node.js module that allows manipulating audio streams from/to soundcards and work with the fft of the signal etc.
There are many javascript audio libraries, but most of them make assumptions about using Web Audio API or that audio is being manipulated in real time. Audio-fns takes a different approach, providing functions to generate and operate on audio samples wher
Customizable O(1) ES6 generators for colored noise
Streaming frequency detection using the Goertzel algorithm
Audio processing, such as pitch detection, fft, mfcc and converting AMR NB/WB to Wave PCM data.
Simple pure Javascript implementation of the Cooley-Tukey algorithm. Note: fft-js was chosen as the name since a lot of the FFT implementations on NPM at the time this was published were wrappers for Ruby or C.
