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.

Add a compatibility option to treat cone angles as half angles
...
All previous versions of the library treated the source cone angles as half
angles, which is contrary to the spec. Setting the __ALSOFT_HALF_ANGLE_CONES
environment variable to "true" or "1" restores the buggy behavior for
compatibility with applications that expect it.
This is not a config file option because new apps should not be made to depend
on the old behavior.

Apply the device matrix to the multi-channel source matrix
...
Mono sources and effects already output according to the available output
device channels. Multiplying the device matrix with the source matrix results
in a matrix that has the same effect as applying the source matrix followed by
the device matrix, so all the channel remixing can be done in one place.
