Implement a simplistic MSADPCM encoder
...
It's not particularly good, but it's better than silence.

Use specialized methods for converting ALshort to IMA4 and MSADPCM
...
As before, to avoid unnecessary direct copies
2014-03-05 06:13:00 -08:00
f82f3f10ab
Use specialized methods for converting IMA4 and MSADPCM to ALshort
...
Since the decoder methods already convert to ALshort, there's no need to use a
temp buffer that's just going to copy directly to the destination.

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);

Use alloca for temp space decoding/encoding IMA4 blocks
2014-03-03 20:02:15 -08:00
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.

Handle fontsound sample types using explicit enum values
...
Uses AL_MONO_SOFT, AL_RIGHT_SOFT, and AL_LEFT_SOFT. "Linked" samples types
aren't explicitly supported due to being under-defined in the SF2 spec, nor are
ROM samples currently.
