* | Remove the now-unneeded click removal buffers for the device | Chris Robinson | 2014-03-23 | 8 | -66/+19 |
| | | | | | | They are still there for auxiliary sends. However, they should go away soon enough too, and then we won't have to mess around with calculating extra "predictive" samples in the mixer. | ||||
* | Don't feed the HRTF mix to the click removal and pending click buffers | Chris Robinson | 2014-03-23 | 1 | -40/+3 |
| | | | | | The coefficients (which control the volume and panning) already use stepping to non-abruptly fade the mix. | ||||
* | Step mixing gains per-sample for non-HRTF mixing | Chris Robinson | 2014-03-23 | 6 | -58/+205 |
| | | | | | | | | | | | | | | | | | | | | | | | | This fades the dry mixing gains using a logarithmic curve, which should produce a smoother transition than a linear one. It functions similarly to a linear fade except that step = (target - current) / numsteps; ... gain += step; becomes step = powf(target / current, 1.0f / numsteps); ... gain *= step; where 'target' and 'current' are clamped to a lower bound that is greater than 0 (which makes no sense on a logarithmic scale). Consequently, the non-HRTF direct mixers do not do not feed into the click removal and pending click buffers, as this per-sample fading would do an adequate job of stopping clicks and pops caused by extreme gain changes. These buffers should be removed shortly. | ||||

* | Add a stub 'soft' MIDI synth handler | Chris Robinson | 2014-03-22 | 2 | -0/+143 |
| | | | | | Eventually this one will be used to handle MIDI internally, using our own mixers and resamplers. | ||||

* | Use flexible array members to pad the device and context structs | Chris Robinson | 2014-03-20 | 1 | -4/+4 |
| | | | | | This helps avoid the convoluted math otherwise required to ensure the default slot and listener, respectively, are aligned. | ||||
* | Keep track of the mix count | Chris Robinson | 2014-03-19 | 1 | -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. | ||||

* | Remove the Apple-specific atomic function implementations. | Chris Robinson | 2014-03-09 | 1 | -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 formats | Chris Robinson | 2014-03-04 | 1 | -1/+3 |
| | |||||
* | Add an extension to alter the block alignment for buffer unpack/pack ops | Chris Robinson | 2014-03-04 | 1 | -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); | ||||

| | | | | Unable to test, but it hopefully works. | ||||
* | Revert "Apply HRTF coefficient stepping separately" | Chris Robinson | 2014-02-23 | 4 | -19/+74 |
| | | | | | | | | | This reverts commit 25b9c3d0c15e959d544f5d0ac7ea507ea5f6d69f. Conflicts: Alc/mixer_neon.c Unfortunately this also undoes the Neon-enhanced ApplyCoeffsStep method. | ||||

| | |||||
* | Check the hrtf config option earlier | Chris Robinson | 2014-02-23 | 1 | -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 twice | Chris Robinson | 2014-02-23 | 1 | -2/+3 |
