Source

Full source code is linked below and together with assets also available in the magnum-examples GitHub repository. This example depends on the Audio library and the StbVorbisAudioImporter plugin which is not a part of the core Magnum repository, see their documentation for usage instructions.

The ports branch contains additional patches for Emscripten support that aren't present in master in order to keep the example code as simple as possible.
