* Add AL_SOFT_UHJ_ex to the extension listChris Robinson2023-02-263-10/+8
|
* Add formats for UHJ with muLaw, and ADPCM for 2-channel UHJChris Robinson2023-02-261-1/+11
| | | | | | | | | | ADPCM doesn't seem to be well defined for more than two channels, even though there doesn't seem to be any issue with simply increasing the channel step over interleaved data (ffmpeg refuses to create IMA4 or MSADPCM files with more than two channels, and its decoder behaves oddly different when channels > 2). So IMA4 and MSADPCM can only safely handle 2-channel UHJ. There's no problem with muLaw supporting 2-, 3-, or 4-channel UHJ though.
* Support MSADPCM samples in the mixerChris Robinson2023-02-141-0/+1
|
* Support IMA4 ADPCM as a mixing voice formatChris Robinson2023-02-141-0/+4
|
* Separate decoding and mixing from resamplingChris Robinson2023-02-121-6/+0
|
* Check a string for NULL before calling strtoullChris Robinson2023-02-111-8/+9
|
* Use a span to hold the cubic table referenceChris Robinson2023-02-101-1/+1
|
* Use better panning positions for the frequency shifter effectChris Robinson2023-02-081-2/+7
|
* Use better panning positions for the chorus effectChris Robinson2023-02-081-56/+61
| | | | Also avoid putting larger buffers on the stack.
* Make a table constexprChris Robinson2023-02-071-6/+5
|
* Rename the bsinc table variablesChris Robinson2023-02-071-2/+2
|
* Use an interpolated FIR filter for cubic resamplingChris Robinson2023-02-061-0/+11
| | | | | | Similar to how the bsinc filters work, but optimized for 4-point filtering. At least the SSE version is notably faster than calculating the coefficients in real time.
* Avoid using auto for lambda parametersChris Robinson2023-02-062-2/+2
|
* Improve performance calculating reverb panningChris Robinson2023-02-051-10/+11
|
* Use a cubic resampler for the reverb modulator offsetChris Robinson2023-02-051-17/+61
|
* Don't set an EAX version by default for sourcesChris Robinson2023-02-051-9/+0
| | | | | | | | | Presuming sources start in a neutral state for EAX effects, that is they're not affected by EAX by default, there's no need to set an active EAX state for one until the app sets an EAX property on it. Since the deferred and immediate properties are stored independently per-version, they can always be set to defaults, and simply not have a particular version committed as active until the app sets an EAX property, which will inherently set the active version.
* Distinguish a couple log messagesChris Robinson2023-01-301-3/+3
| | | | And downgrade an ERR to a WARN
* Transpose the ambisonic rotation matrix and helper coefficientsChris Robinson2023-01-261-39/+32
|
* Transpose the ambisonic voice mixing matrixChris Robinson2023-01-251-34/+41
| | | | | To more efficiently prepare the panning coefficients. Also avoid making a stack copy of the matrix to reuse as the target.
* Use explicit arrays for the remix table target mixesChris Robinson2023-01-241-16/+53
| | | | Seems inline initializer lists become garbage when stored in a span.
* Use the object serial ID from PipeWire when availableChris Robinson2023-01-241-21/+47
| | | | | | | | | | | Using the node ID as a target is deprecated in newer versions of PipeWire. The serial ID is a monotonic 64-bit integer ID, incremeneted for every object created, so is guaranteed to always refer to the same target (until it wraps around, which I suppose isn't expected/allowed to happen), compared to the 32-bit node ID which I guess allows reuse. We could instead use the target node's name instead of the serial ID, but an integer is nicer to manage than a string.
* Increase the pitch shifter oversample factor to 8Chris Robinson2023-01-191-38/+37
| | | | | | And use 32-bit float processing. Float precision doesn't seem to be detrimental to the overall quality, while 8x oversampling seems to help against the harmonics.
* Minor code refactor for the frequency shifter effectChris Robinson2023-01-191-47/+50
|
* Improve the output scaling of the pitch shifterChris Robinson2023-01-191-1/+1
| | | | | | For tones than land exactly on a frequency bin, which are subject to the least amount of error when not adjusted, this produces a level that more closely matches the original input.
* Don't return a large-ish array on the stackChris Robinson2023-01-191-15/+17
|
* Slightly improve phase wrapping in the pitch shifterChris Robinson2023-01-191-10/+11
|
* Limit pitch shifter pitch between 0.5 and 2.Chris Robinson2023-01-181-1/+1
| | | | | | The current algorithm isn't designed to go beyond that. The course tuning property is limited to that range as well, though the fine tuning property could potentially extend it out by half a semitone.
* Use constexpr variables instead of macrosChris Robinson2023-01-181-51/+57
