* | Remove the now-unneeded click removal buffers for the device | Chris Robinson | 2014-03-23 | 2 | -7/+1 |
| | | | | | | 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. | ||||
* | Step mixing gains per-sample for non-HRTF mixing | Chris Robinson | 2014-03-23 | 1 | -2/+7 |
| | | | | | | | | | | | | | | | | | | | | | | | | 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 | 1 | -1/+3 |

* | Use flexible array members to pad the device and context structs | Chris Robinson | 2014-03-20 | 1 | -0/+6 |
| | | | | | 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/+7 |
| | | | | | | | | | | | | | | | | | | | | | | | | 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. | ||||

| | | | | It's not particularly good, but it's better than silence. | ||||

* | Use specialized methods for converting IMA4 and MSADPCM to ALshort | Chris Robinson | 2014-03-05 | 1 | -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. | ||||

* | Add an extension to alter the block alignment for buffer unpack/pack ops | Chris Robinson | 2014-03-04 | 3 | -16/+80 |
| | | | | | | | | | | | | | | | | 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); |
