Package Exports
- web-audio-analyser
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (web-audio-analyser) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
web-audio-analyser 
A thin wrapper around the Web Audio API that takes an <audio> element and
gives you its waveform/frequency data in return.
Usage
analyser = require('web-audio-analyser')(audio[, ctx])
Takes an <audio> element as its first argument - optionally, you can pass
your own AudioContext instance too.
analyser.waveform([ui8array])
Copies the audio's current time-domain data into a Uint8Array. If you don't
pass your own in, one will be created for you: this will be reused, so it's
safe to call in an animation loop.
analyser.frequencies([ui8array])
Much like analyser.waveform, with the exception of copying the audio's
currrent frequency data into a Uint8Array.
