a1c440bd09 Add an extension to support MSADPCM buffer formats 2014-03-04 22:44:30 -08:00
Chris Robinson
f3a87d72b2 Add an extension to alter the block alignment for buffer unpack/pack ops 
This is for unpacking (reading, e.g. alBufferData) and packing (writing, e.g.
alGetBufferSamplesSOFT) operations. The alignments are specified in sample
frames, with 0 meaning the default (65 for IMA4, 1 otherwise). IMA4 alignment
must be a multiple of 8, plus 1 (e.g. alignment = n*8 + 1), otherwise an error
will occur during (un)packing. Chenging the block alignment does not affect
already-loaded sample data, only future unpack/pack operations... so for
example, this is perfectly valid:

// Load mono IMA4 data with a block alignment of 1024 bytes, or 2041 sample
// frames.
alBufferi(buffer, AL_UNPACK_BLOCK_ALIGNMENT_SOFT, 2041);
alBufferData(buffer, AL_FORMAT_MONO_IMA4, data, data_len, srate);
alBufferi(buffer, AL_UNPACK_BLOCK_ALIGNMENT_SOFT, 0);

a2d9133ffc Reduce explicit template declarations and ignore IMA4-to-IMA4 conversions 
Since we never store IMA4 data in buffers, we should only ever convert from
(user input) or to (user output) IMA4. Once we allow user-specified pack/unpack
block alignment, this wouldn't be a simple memcpy anyway.

9a4ded2491 Revert "Apply HRTF coefficient stepping separately" 
This reverts commit 25b9c3d0c15e959d544f5d0ac7ea507ea5f6d69f.

Conflicts:
	Alc/mixer_neon.c

Unfortunately this also undoes the Neon-enhanced ApplyCoeffsStep method.

ef8002a832 Check the hrtf config option earlier 
This is to make sure it tries to find an HRTF-compatible format before reseting
the device, just like when using ALC_HRTF_SOFT.

ea0aea6508 Change the autowah to have a cutoff range of 20Hz to 20KHz 
This is the same as allowed in the SF2 spec for its filter cutoff generator,
which can be used for a wah effect in MIDI. It makes sense to use a similar
range here.

7c4339c195 Rework MIDI clock timing 
It's best to avoid using doubles in the mixer since the FPU's set to single-
precision mode. The new clock timing is similar to the device clock timing, and
should hopefully be less prone to drift caused by fp rounding errors.

755f161fc5 Use nanosecond resolution for MIDI 
This makes the MIDI clock use the same resolution as the device clock and
source latency and the device clock.
