* Keep track of the mix countChris Robinson2014-03-191-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | The purpose of this is to provide a safe way to be able to "swap" resources used by the mixer from other threads without the need to block the mixer, as well as a way to track when mixes have occurred. The idea is two-fold: It provides a way to safely swap resources. If the mixer were to (atomically) get a reference to an object to access it from, another thread would be able allocate and prepare a new object then swap the reference to it with the stored one. The other thread would then be able to wait until (count&1) is clear, indicating the mixer is not running, before safely freeing the old object for the mixer to use the new one. It also provides a way to tell if the mixer has run. With this, a thread would be able to read multiple values, which could be altered by the mixer, without requiring a mixer lock. Comparing the before and after counts for inequality would signify if the mixer has (started to) run, indicating the values may be out of sync and should try getting them again. Of course, it will still need something like a RWLock to ensure another (non-mixer) thread doesn't try to write to the values at the same time. Note that because of the possibility of overflow, the counter is not reliable as an absolute count.

* Return the original value from CompExchange*Chris Robinson2014-03-093-30/+27
|
* 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).
* Add an extension to support MSADPCM buffer formatsChris Robinson2014-03-041-1/+3
|
* Add an extension to alter the block alignment for buffer unpack/pack opsChris Robinson2014-03-041-3/+5
| | | | | | | | | | | | | | | | 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);

* Move OpenDataFile to helpers.c so other sources can use itChris Robinson2014-02-272-131/+133

* Add an explicit cast to make Windows happyChris Robinson2014-02-261-2/+2

* Expand environment variables for all config option values when loadingChris Robinson2014-02-262-31/+77

* Support environment variables in the hrtf_tables config valueChris Robinson2014-02-251-4/+34
|
* 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 Robinson2014-02-234-0/+31
|
* Move the default hrtf table to an external fileChris Robinson2014-02-232-878/+12
|
* Add a return value to FindHrtfFormatChris Robinson2014-02-232-7/+9
|
* 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 Robinson2014-02-231-1/+126

* 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.
* Fix some typesChris Robinson2014-02-072-4/+4

* Slightly shorten a long lineChris Robinson2014-02-021-1/+1
|
* Rework MIDI clock timingChris Robinson2014-02-024-123/+62
| | | | | | 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.
* Use nanosecond resolution for MIDIChris Robinson2014-02-011-2/+2
| | | | | This makes the MIDI clock use the same resolution as the device clock and source latency and the device clock.
* Remove an unnecessary special-case for the click removalChris Robinson2014-02-011-14/+1
|
* Avoid duplicating code in alcGetIntegervChris Robinson2014-02-011-241/+152
