alsa

README

go-alsa

A pure Go audio binding to ALSA that supports audio playback.

WARNING

The public API is unstable. Please fork/vendor before using. Right now it's inspired by oto, but only the player part is implemented, and some features are missing that alsa-lib might do to make it plug-and-play:

• format conversion
• channel conversion
• resampling

TODO

This library implements the bare minimum of the rich alsa API. What's missing:

• hardware feature detection (sample rate, channels, formats)
• capture
• non-interleaved audio playback
• mmap-based API (less copying)
• others
