* Fix for MSVC decaying arrays to pointers with ?:Chris Robinson2019-03-091-5/+5
|
* Fade out voices that end normallyChris Robinson2019-03-091-140/+180
| | | | | | Sometimes a sound may end with non-0 amplitude, particularly if a buffer queue underruns. This helps avoid clicks and pops for sources that don't already end in silence.
* Play dummy samples and force a fade out on stopping voicesChris Robinson2019-03-093-26/+45
|
* Add a Stopping state for voicesChris Robinson2019-03-095-39/+104
| | | | | | This currently doesn't do much, except have the mixer progress it to Stopped. It's valid to have without a source or buffers, and in the future will allow fading out when a source is paused or stopped.
* Increment the active voice count ahead of playing the sourcesChris Robinson2019-03-091-7/+27
|
* Clear the voice's buffer when detaching from sourceChris Robinson2019-03-092-0/+10
|
* Exclude far-ear IRs for the synthesized -90 degree elevationChris Robinson2019-03-091-5/+35
|
* Avoid some explicit loopsChris Robinson2019-03-051-107/+118
|
* Normalize HRIRs using their maximum RMSChris Robinson2019-03-041-2/+23
|
* Pass a reference to function for a template parameterChris Robinson2019-03-031-3/+3
|
* Use more specific names for temp buffer storageChris Robinson2019-03-022-19/+13
|
* Use a proper flag to indicate audio is prepared in alffplayChris Robinson2019-03-011-14/+9
|
* Reverse the HRTF field arrayChris Robinson2019-02-273-15/+24
| | | | | | Most often a sound's distance will be beyond the farthest field measurement, so It's more efficient to have the farthest field first and avoid looping through the whole field array for them.
* Combine the reverb output mixes into a single callChris Robinson2019-02-251-28/+38
|
* Unlock the audio decoder mutex before disabling events in alffplayChris Robinson2019-02-251-2/+3
| | | | | The callback may be waiting on the mutex, but disabling the callback needs any current invocation to finish first.
* Make sure the reverb fading completesChris Robinson2019-02-251-1/+1
| | | | | The processing loop doesn't depend on being aligned anymore, so it won't get stuck when only less than 4 samples can be done in a non-final update.
* Convert the device frequency to float just onceChris Robinson2019-02-241-9/+7
|
* Make sure the voice's direct buffer is always setChris Robinson2019-02-241-7/+5
|
* Remove a duplicate index arrayChris Robinson2019-02-241-2/+2
|
* Reduce BUFFERSIZE to match the default period sizeChris Robinson2019-02-243-16/+18
| | | | | Also adds a bit more space to the temp source data buffer, to avoid needing to loop on matching sample rates.
* Rework reverb A/B-Format conversion mixingChris Robinson2019-02-241-99/+77
| | | | | This should help improve performance using the optimized mixers, and fewer passes on the transforms, though at the cost of more memory.
* Change some functions to proper methodsChris Robinson2019-02-231-171/+171
|
* Avoid multiple int-to-float conversionsChris Robinson2019-02-231-12/+17
|
* Constify some parameters and remove an explicit loopChris Robinson2019-02-232-10/+23
|
* Remove the FOAOut mixing buffer and associated post-processesChris Robinson2019-02-228-298/+14
|
* Remove the unused FOAOut EffectTargetChris Robinson2019-02-222-3/+2
|
* Apply ambisonic upsampling on reverb output as neededChris Robinson2019-02-221-37/+110
| | | | | | | | | | This isn't the greatest thing since it splits the A-to-B-Format transform from the panning transform. The A-to-B and HF scale mixes are also not as optimal as they could be, since they can't use the main mixer functions (wrong buffer line length). It does, however, get rid of the final use of the FOAOut buffer, so the upsampling post-process is no longer needed.
* Ensure reverb fading doesn't end with less than 4 samplesChris Robinson2019-02-221-1/+1
|
* Avoid some unnecessary local variablesChris Robinson2019-02-221-13/+12
|
* Combine reverb transform matrices one column at a timeChris Robinson2019-02-211-18/+23
|
* Mix B-Format sources directly to the dry bufferChris Robinson2019-02-212-21/+34
| | | | Now the only thing that utilizes FOAOut is reverb output.
* Remove RESTRICT from the bandsplitter process methodChris Robinson2019-02-212-2/+2
| | | | | The compiler can see there's no aliasing with the local variables, and the input/output buffers are handled sequentially one element at a time anyway.
* Add some preliminary fields for mix-time ambisonic upsamplingChris Robinson2019-02-212-4/+23
|
* Allow processing some effects in higher order ambisonicsChris Robinson2019-02-218-19/+19
| | | | | | Reverb notably is still only first-order (any higher order channels are dropped, and it writes to FOAOut). But others, like the equalizer, work on all available channels.
* Add helpers to get the channel count from an ambisonic orderChris Robinson2019-02-213-16/+20
|
* Fix unused parameter warningChris Robinson2019-02-211-1/+1
|
* Get rid of the MAX_EFFECT_CHANNELS macroChris Robinson2019-02-215-43/+39
|
* Make sure the B2A matrix has enough values for the input countChris Robinson2019-02-211-6/+6
|
* Remove some now-unnecessary ReverbState fieldsChris Robinson2019-02-211-26/+1
|
* Pass the number of input channels to EffectState::processChris Robinson2019-02-2114-108/+105
|
* Add a method to get the row of an ambisonic identity transformChris Robinson2019-02-211-0/+7
|
* Ensure the device's mAmbiOrder is always set appropriatelyChris Robinson2019-02-211-8/+23
| | | | The Dry target is always ambisonic, so set its order correctly.
