libao: a cross platform audio library
Libao is a cross-platform audio library that allows programs to output audio using a simple API on a wide variety of platforms. It currently supports:
- Null output (handy for testing without a sound device)
- WAV files
- AU files
- OSS (Open Sound System, used on Linux and FreeBSD)
- ALSA (Advanced Linux Sound Architecture)
- PulseAudio (next generation GNOME sound server)
- esd (EsounD or Enlightened Sound Daemon)
- AIX
- Sun/NetBSD/OpenBSD
- IRIX
- NAS (Network Audio Server)
Please report bugs at trac.xiph.org or email them to Stan Seibert <volsung@xiph.org>.

Changelog
- Incorporated OS X patches from the Fink team.
- AIX output plugin by Stefan Tibus.

- NAS plugin from Antoine Mathys.
- Portability fixes for various platforms (including dlopen() bugs) including HP-UX and *BSD.
- Memory/resource leak fixes
- Significant fixes to ALSA 0.9.x plugin by Kevin Cody, Jr. This should fix stuttering audio for mpg321 users. The --enable-alsa09-mmap option to ./configure turns on memory-mapped I/O. Note this is an experimental feature and causes some problems with some sound card drivers and also users of the dmix software mixer.
