this project is inspired by OggVorbisEncoder.js.
Installation
$ npm install vorbis-encoder-js
Usage
var Encoder = require("vorbis-encoder-js").encoder;
var sampleRate = audioBuffer.sampleRate;
var numberOfChannels = audioBuffer.numberOfChannels;
var quality = 0; // -0.1 to 1 (Vorbis quality)
var tags = {
TITLE: "test_ogg",
ALBUM: "テストアルバム", // UTF-8 is usable
ARTIST: "miyabisun",
LOOPSTART: "10000",
LOOPLENGTH: "30000"
};
var encoder = new Encoder(sampleRate, numberOfChannels, quality, tags);
encoder.encodeFrom(audioBuffer);
var blob = encoder.finish();
Build
Docker and Node.js are required to build the library.
