|
* Remove the Apple-specific atomic function implementations.Chris Robinson2014-03-091-36/+0
| | | | | | I'm not sure if they're even used, but they were rather ugly and are set to get even uglier since they don't follow normal conventions (missing exchange, and cas not returning the original value).
* Update config file commentsChris Robinson2014-03-091-17/+29

* Move the sample conversion routines to a separate fileChris Robinson2014-03-054-1261/+1279
|
* Implement a simplistic MSADPCM encoderChris Robinson2014-03-051-19/+47
| | | | It's not particularly good, but it's better than silence.
* Allocate enough temp space for the ADPCM decoders and encodersChris Robinson2014-03-051-4/+4
|
* Use specialized methods for converting ALshort to IMA4 and MSADPCMChris Robinson2014-03-051-2/+32
| | | | As before, to avoid unnecessary direct copies
* Use specialized methods for converting IMA4 and MSADPCM to ALshortChris Robinson2014-03-051-8/+39
| | | | | 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.
* Use maxi to clamp an int to a lower-boundChris Robinson2014-03-051-1/+1
|
* Expand the sign bit on the initial MSADPCM delta valueChris Robinson2014-03-051-0/+1
|
* Add an extension to support MSADPCM buffer formatsChris Robinson2014-03-045-28/+342
|
* Add an extension to alter the block alignment for buffer unpack/pack opsChris Robinson2014-03-044-19/+85
| | | | | | | | | | | | | | | | 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);
* Parameterize the block alignmentChris Robinson2014-03-041-111/+152
|
* Use alloca for temp space decoding/encoding IMA4 blocksChris Robinson2014-03-033-4/+28
|
* Reduce explicit template declarations and ignore IMA4-to-IMA4 conversionsChris Robinson2014-03-031-159/+35
| | | | | | 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.
* Store the original frame size alignment in the bufferChris Robinson2014-03-033-12/+29
|
* Move PATH_MAX fallback definitions to alMain.hChris Robinson2014-02-275-31/+9
|
* Add back the missing PATH_MAX fallbackChris Robinson2014-02-271-0/+10

* Use OpenDataFile to load soundfonts relative to data directoriesChris Robinson2014-02-272-2/+8
|
* Add a note that absolute paths may be used for hrtf_tablesChris Robinson2014-02-271-0/+1
|
* Move OpenDataFile to helpers.c so other sources can use itChris Robinson2014-02-273-131/+134
|
* Add an explicit cast to make Windows happyChris Robinson2014-02-261-2/+2

* Fix a config option commentChris Robinson2014-02-231-3/+2
|
* Attempt to restore the Neon-enhanced ApplyCoeffsStep methodChris Robinson2014-02-231-7/+21
| | | | Unable to test, but it hopefully works.
* Revert "Apply HRTF coefficient stepping separately"Chris Robinson2014-02-234-19/+74
| | | | | | | | | This reverts commit 25b9c3d0c15e959d544f5d0ac7ea507ea5f6d69f. Conflicts: Alc/mixer_neon.c Unfortunately this also undoes the Neon-enhanced ApplyCoeffsStep method.
* Move HRTF macros and function declarations to a separate headerChris Robinson2014-02-236-14/+32
|
* Move the default hrtf table to an external fileChris Robinson2014-02-236-884/+28
|
* Add a return value to FindHrtfFormatChris Robinson2014-02-233-8/+10
|
* Check the hrtf config option earlierChris Robinson2014-02-231-8/+8
| | | | | This is to make sure it tries to find an HRTF-compatible format before reseting the device, just like when using ALC_HRTF_SOFT.
* Avoid checking the hrtf config option twiceChris Robinson2014-02-231-2/+3
|
* Search system-dependant data paths for relative hrtf table filenamesChris Robinson2014-02-232-4/+133

* Avoid using a global static buffer for config loadingChris Robinson2014-02-231-3/+51

* Fix indentationChris Robinson2014-02-231-20/+20

* Fix a race condition in the mmdevapi message queue threadChris Robinson2014-02-091-0/+6
|
* Add some extra traces to the mmdevapi backendChris Robinson2014-02-091-0/+8
| | | | Trying to track down the cause of some reported errors.
* Change the autowah to have a cutoff range of 20Hz to 20KHzChris Robinson2014-02-071-1/+1
| | | | | | 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.
