Next release up and ready for download.
http://kcat.strangesoft.net/openal.htmlLots of changes in this release. They include initial support for
ALC_EXT_disconnect on some backends (mainly ALSA, OSS, Solaris, and the Wave
Writer). It can also output 32-bit float for backends that can handle it
(ALSA, DSound, PortAudio, and PulseAudio), and capture can take the mono and
stereo float formats (ALSA and PulseAudio only). The ALC_FREQUENCY context
attribute will now try to change the playback rate of the device, setting a
rate that matches as closely as possible.
Of important note for users that have config files, there's been some changes.
The backend-specific 'periods' options will no longer work.. instead, it's
been made a global option. Additionally, the poorly named 'refresh' option is
deprecated and will be removed for the next version. It's replaced by the
period_size option, which is the number of sample frames mixed for every sound
update. It is multiplied by the periods to get the full buffer size in sample
frames. Ie..
buffer_size = periods*period_size
The old 'refresh' option is analogous to the buffer_size value, so if
period_size is left unset, you will get:
period_size = refresh/periods
The default is 4 periods of 1K frames each.
Current plans for OpenAL Soft 1.10 are multiple contexts per device, and
hopefully finalizing the ALC_EXT_thread_local_context extension (and the
others; which, incidentally, is first on the agenda). I'd like to see OpenAL
get more modular so that multiple plugins, that use OpenAL, can operate within
a single program without tripping all over each other.
Feel free to toss questions and/or comments my way. Thanks for looking!
