Installation
$ npm install vorbis-encoder-jsUsage
var Encoder = require("vorbis-encoder-js").encoder;
var sampleRate = audioBuffer.sampleRate;
var numberOfChannels = audioBuffer.numberOfChannels;
var quality = 0; // -1 to 1
var tags = {
TITLE: "test_ogg",
ALBUM: "テストアルバム",
Artist: "みやびさん",
LOOPSTART: "10000",
LOOPLENGTH: "30000"
};
var encoder = new Encoder(sampleRate, numberOfChannels, quality, tags);
encoder.encodeFrom(audioBuffer);
var blob = encoder.finish();
