stbvorbis.js
A JavaScript port of stb_vorbis.c.
Usage
Download files from Releases. Copy stbvorbis.js and stbvorbis_asm.js to your file server and load stbvorbis.js via a script tag.
This library basically uses WebAssembly. stbvorbis.js also has asm.js implementation for environments where WebAssembly is not available. On iOS, stbvorbis.js always uses asm.js instead due to instability of iOS WebAssembly implementation. If stbvorbis_asm.js is in the same directory as stbvorbis.js, asm.js version works as fallback.
API
decode
stbvorbis.decode(buf: ArrayBuffer|Uint8Array, callback: function(event: Object))
decode decodes the given Ogg/Vorbis data.
The given callback is called when decoding proceeded or error happens. The argument is an object that has these keys:
| name | description |
|---|---|
data | An array of Float32Array that represents decoded stream for each channel. |
sampleRate | The sample rate like 44100. |
eof | True if the stream ends, otherwise false. If this is true, data is null. |
error | An error string if exists, otherwise null. |
decodeStream
stbvorbis.decodeStream(callback: function(event: Object)): function(event: Object)
decodeStream decodes the given Ogg/Vorbis stream.
The given callback is called when decoding proceeded or error happens. The argument is an object that has these keys:
| name | description |
|---|---|
data | An array of Float32Array that represents decoded stream for each channel. The length can be more than or equal to 0. |
sampleRate | The sample rate like 44100. |
eof | True if the stream ends, otherwise false. If this is true, data is null. |
error | An error string if exists, otherwise null. |
The returned function is used to push input strem. The argument is an object that has these keys:
| name | description |
|---|---|
data | ArrayBuffer or Uint8Array that represents encoded stream. |
eof | True if the stream ends, otherwise false. If this is true, data is ignored. |
