vorbis-tools 1.4.0, libvorbis 1.3.1, and libao 1.0.0 coordinated release

libao 1.0.0 released
libVorbis 1.3.1 released
vorbis-tools 1.4.0 released

Xiph.Org announces the release of libao-1.0.0, libvorbis-1.3.1 and vorbis-tools-1.4.0. This is a coordinated update of the audio libraries and tools to deploy improved surround-sound support across the libraries and toolchain.

libao improvements
  • AO returned to active development
  • Added surround channel mapping API and capability
  • Updated all drivers on modern installs
  • New config file options
  • Driver options may be specified in config file
  • Support for MacOSX updated to 10.5 and later
  • Build in WMM driver rather than using dlopen()
  • Added Roar Audio driver
  • Added OpenBSD SNDIO driver
  • Workaround for ESD non-4096 byte write bug
  • Workaround aRts server crash bug
  • Workaround for VIA82xx click/crackle bugs under ALSA
  • Remove dead/unused drivers (solaris, alasa05, mmsound)
  • Numerous patches from multiple downstreams

libvorbis improvements
libVorbis 1.3.0 was briefly available as an unreleased staging snapshot. This official release bumps the version number to 1.3.1 to avoid any possible confusion.
  • Optimized/coupled surround support for 5.1 encoding at 44.1/48kHz
  • Added encoder control call to disable channel coupling
  • Corrected an overflow bug in very low-bitrate encoding on 32 bit machines that caused inflated bitrates
  • Numerous API hardening, leak and build fixes
  • Correct bug in 22kHz compand setup that could cause a crash
  • Correct bug in 16kHz codebooks that could cause unstable pure tones at high bitrates

vorbis-tools improvements
vorbis-tools 1.4.0 is the first official release of vorbis-tools since 1.2.x. 1.3.x was never offered as an official snapshot, though various versions were widely deployed as patch-sets by distributions.
  • Implement corrected channel mappings for all input and playback file types
  • Correct an possible infinite loop in WAV input reading code when header is corrupt
  • Implement "disable_coupling" option for oggenc
  • Fix Ctrl-C lockup bug in ogg123
  • ogg123 directory playback in sorted order
  • More translations
  • Add '-' as stdin/out filename in vcut
  • Add -lnetwork check for socket in configure
  • Remove 'extra' F parameter from ogg123 remote output
  • Numerous code and build fixes


The libao 1.0.0 release is available from http://downloads.xiph.org/releases/ao/

The libvorbis 1.3.1 and vorbis-tools 1.4.0 releases are available from http://downloads.xiph.org/releases/vorbis/

Happy hacking!

"Aside from bugfixes, the major story here is the first wide release of all the surround hacking I've been doing the past two months. Previous demo pages (one and two) had documented my progress till now; there's actually one more coming that I've just started on.

In addition to that, we also tagged on a release of libogg with a new default page spill rule that reduces container overhead for higher bitrate streams like video. The change is simple, but it's a reduction in bitrate for free so why not. Applications don't have to do anything, just drop in the new lib. In addition to demo pages and blogging, I've also begun a comprehensive expansion of the Ogg documentation (the very beginnings of which are in the release-- not much yet)."
