nodejs port for fftw
Whistle detector made with WebAudio API. Works in browsers and node.
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
