node-openal
This addon makes it possible to use the OpenAL library from within a node application.
Helpful Sources
I didn't know anything about OpenAL or creating c++ node "addons" before starting this, so I got a lot of help from the following sources:
- node-midi provided a great example of a nicely designed c++-based node module
- nodejs.org addon manual
- This simple OpenAL example
- OpenAL Programmers Guide
- My OpenAL framework is broken, how can I fix it? (OSX Lion)
Testing
As a newcomer to node addons, rather than setting up the whole Eclipse-based debugging environment, I found it helpful to compile my addon in debug mode and just run node through gdb:
node-gyp clean && node-gyp configure && node-gyp build --debug
gdb node
(gdb) set args test/stream.js
(gdb) run
Even though node isn't compiled with debug symbols, this got me close enough to the problem when I was getting weird segfaults.
To do
- Use libuv for stream reading?
- OpenAL-soft air absorption, occlusion, and environmental reverb
- same as EFX?
- use MPlayer for compressed formats? or ogg
- ultimately, I want to be able to stream the audio that is generated. Is this article relavant?
