* Move the bnad-splitter filters to a separate sourceChris Robinson2018-04-217-136/+151
|
* Add some more ASSUME statementsChris Robinson2018-04-214-0/+7
|
* Adjust the stereo panning front gainChris Robinson2018-04-191-2/+2
| | | | This gives it a (more) precise -4.5dB gain drop for front-center panned sounds.
* Remove unnecessary undefsChris Robinson2018-04-193-3/+0
|
* Clear ALSA's PCM handle after closing itChris Robinson2018-04-191-0/+1
|
* Add some ASSUME statements that ensure mixing at least 1 sampleChris Robinson2018-04-186-0/+25
|
* Add an ASSUME macro that requires a true conditionChris Robinson2018-04-173-0/+6
|
* Accumulate the B-Format HRTF responses using doublesChris Robinson2018-04-171-9/+24
| | | | | The final result is still truncated to single-precision float, but this should keep the responses more stable as it accumulates the various inputs.
* Don't minimize the HRTF per-response delayChris Robinson2018-04-162-11/+7
| | | | | | The reverts both fa9ab9af7cb559ff9ecc1846f2996265bfbea1ec and 79604c3c0e0f3f71832a09348cc273a38882cc3e. As helpful as it was for the high frequencies, the overall response's gain suffered.
* Rename BiquadState to BiquadFilterChris Robinson2018-04-049-79/+78
|
* Apply biquad and T60 filters using transposed direct form IIChris Robinson2018-04-035-74/+62
|
* Initialize COM using the multithreaded apartmentChris Robinson2018-04-011-7/+7
| | | | | | | I honestly have no idea which is the correct (or better) mode to use given the confusing mess COM is, but CoInitialize uses single-threaded apartments which seems to be a problem for with at least a couple games in the STALKER series (the call fails, which causes us to drop back to the DSound backend).
* Limit the near-field control distance to 10m.Chris Robinson2018-03-311-2/+2
|
* Fix HRTF HOA coefficientsChris Robinson2018-03-311-21/+37
| | | | | | ACN8 was accidentally put on ACN7. However, rather than adding the missing channel of silence, set up the coefficient map to only use the ambisonic channels that can contribute to output.
* Apply the initial decay and air absorption after gain clampingChris Robinson2018-03-291-42/+42
|
* Pass the azimuth and elevation to CalcPanningAndFiltersChris Robinson2018-03-291-42/+32
|
* Combine two loopsChris Robinson2018-03-291-27/+25
|
* Check all buffers to update a source withChris Robinson2018-03-281-2/+5
|
* Store the ALbufferlistitem's composited/max sample lengthChris Robinson2018-03-271-26/+6
|
* Rename NfcFilterUpdate* to NfcFilterProcess* for consistencyChris Robinson2018-03-273-8/+8
|
* Condense an if checkChris Robinson2018-03-261-3/+2
|
* Clear mixing target parameters before setting themChris Robinson2018-03-251-70/+23
|
* Reduce the gain of front-panned sounds with plain stereoChris Robinson2018-03-251-2/+2
| | | | | | Now front-center sounds are attenuated by roughly -4.5dB instead of -3dB. This will help keep rear-panned sounds from attenuating too much while not making front-panned also attenuate too much.
* Annotate the B-Format rotation/conversion matrixChris Robinson2018-03-251-7/+11

* Fix a delta phase offset calculation in the pitch shifterChris Robinson2018-03-221-1/+1
