oggdec-wasm

Decode ogg files in the browser using vorbis tools' oggdec via emscripten.

Most browsers play Ogg audio natively, but Safari doesn't, nor does any iOS browser. I have some Ogg piano samples that I want to use in another project I'm working on, and I don't want to exclude those browsers, nor do I want to transcode the Oggs. So I compiled Xiph's libogg/libvorbis/vorbis-tools c libraries to WebAssembly using Emscripten. I made a Makefile to automate the process.

The Makfile, along with pre.js, produces oggdec.js, which you can use like this:

import module from "./oggdec"
const Module = module()
const decodeOggData = Module.decodeOggData
const decodedData = decodeOggData([...some array buffer...])

If you know you're going to decode ogg data, it's a drop-in replacement for decodeAudioData.

Makefile tested on Mac and Linux
