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
Add WAVEFORMATEXTENSIBLE support
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

"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)." sayd Monty.
