Whistle detector made with WebAudio API. Works in browsers and node.
Distributes audio frequency data according to a logarithmic scale.
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
