3a8ef2f0d6 Initialize source parameters before adding the source to the map 2011-09-10 21:21:07 -07:00
Chris Robinson
4c8e6dead1 Don't defer stopped and initial source state changes 
Typically when these are set, an app will be releasing the buffer from the
source, possibly to immediately reuse it. There would be an extra burden placed
on the app if it was required to process updates before it could fully release
the buffer from the source.

5736bbc3e4 Add a source property to skip channel virtualization for multi-channel buffers 
With virtualization disabled, channels are mapped directly from input to output
and any input channel that is missing an output is dropped. Any virtualization
effects (such as HRTF filters) for positional cues are also skipped.

The idea is to allow applications a way to play pre-filtered audio that channel
vitualization effects could interfere with.

7d73ac4405 Avoid calling some AL functions from under the context lock 
There are still some more occurances to clear out (deletion in gen error,
effects, some filters), which shall be coming up. There is a possibility for a
deadlock between the listlock and the global/context lock, if another attempt
to get the listlock is made while under the context lock.

56d9418119 Add an HRTF filter for mono sources 
The data is based on the KEMAR HRTF data provided by MIT, which can be found at
<http://sound.media.mit.edu/resources/KEMAR.html>. The compact measurements
were used. See hrtf_tables.inc for more information.

The filter is only available for stereo output, using a 44100hz playback rate.
Note also that it currently only applies to mono sounds, and the cf_level and
head_dampen config options are ignored while it is active.

in case changes need to be done for the EXT version.
