* Improve the room rolloff factor hanldingChris Robinson2023-12-071-79/+100
| | | | | | | | | | Testing with Generic Software shows that the reverb room rolloff factor applies to the currently selected distance model, not necessarily an inverse distance model as described in the EFX docs. Though it should be noted, Generic Software completely ignores AL_EFFECTSLOT_AUXILIARY_SEND_AUTO, never applies the cones to the wet gain, and doesn't clamp to AL_MIX_GAIN and AL_MAX_GAIN for the wet gains. It's unclear if the reverb or source room rolloff factors, or the initial decay, should be imfluenced by the min or max gain properties.

* Make the device clock members atomicChris Robinson2023-12-033-23/+36
| | | | | | Even though they're protected by a SeqLock of sorts, it's still UB to read and write non-atomic vars from different threads. It's fine to do relaxed reads and writes given the lock though, to help alleviate the cost.
* fix printf format for MinGW (#942)Rosen Penev2023-12-032-4/+4
| | | | | | With gcc, mingw uses gnu_printf. With clang, printf is used as it does not support gnu_printf. Use the internal header to match this properly. Signed-off-by: Rosen Penev <[email protected]>
* Adjust the secondary early reflectionsChris Robinson2023-12-021-6/+7
| | | | | | | | | | | | | | This reduces the delay to provide a direct (no delay) line from the early reflections to the late reverb delay buffer. This also reduces the early reflection output gain by half. The reasoning here is that EFX seems to expect only one set of initial reflections, while we use two. And being close enough in time, nearly doubles the amount of output energy. This does seem to improve the "harshness" of certain reverbs, smoothing the difference between reverbs, and makes it more like other implementations (still some work to do on late reverb, though).

* Add query fonction in ALC_SOFT_system_events unreleased extension (#938)MathiusD2023-11-2613-18/+129
| | | | | | | | | | | | | | | | | | | * feat(ALC_SOFT_system_events): Add alcEventIsSupportedSOFT method in ALC_SOFT_system_events unreleased extension The purpose of this addition (to my collection) are allow to retrieve which events are supported and if events are fully supported or if some case isn't managed for some reason For exemple only some backends provide system events: * pipewire -> Full support of extension * wasapi -> Full support of extension * pulseaudio -> Support of add and remove devices events only * coreaudio -> Support of default device change only * feat(ALC_SOFT_system_events): Fix typo in alext.h Cf following review : https://github.com/kcat/openal-soft/pull/938#discussion_r1404509828 * feat(ALC_SOFT_system_events): Remove ALC_EVENT_NOT_SUPPORTED_SOFT token Cf following discussions between this comment : https://github.com/kcat/openal-soft/pull/938#issuecomment-1825876452 to this comment : https://github.com/kcat/openal-soft/pull/938#issuecomment-1826419406
* Do proper spatial reflection in reverbChris Robinson2023-11-221-16/+55
| | | | | | Instead of "bouncing" the lines by indexing backwards for a not-quite-spatial- opposite, do a proper mix that moves each line response to its true spatial opposite position.
* Compensate the late delay tap by the early delay bufferChris Robinson2023-11-221-1/+5

* Don't combine both early reflection taps for the late reverbChris Robinson2023-11-211-2/+3
| | | | | | | | | | | | | | | | | | | It doesn't make much sense to include both early reflections to feed the late reverb, since it increases the total energy in the reverb decay. This better fits with the design described in papers for this type of reverb, and seems to better match volume levels of hardware EAX/EFX reverb (though there are still some apparent differences). Note that this adds a bit more delay to the late reverb, specifically EARLY_LINE_LENGTHS[0] * density_mult. This can be compensated for somewhat by reducing the late reverb delay by that amount (clamping to a minimum of 0). Alternatively, adjust the delay lines for the second early tap to have a zero- delay pass-through line with 3 delay lines (as opposed to the current 4 delay lines), as suggested by the paper "ADAPTING ARTIFICIAL REVERBERATION ARCHITECTURES FOR B-FORMAT SIGNAL PROCESSING". Although doing so may require additional adjustments to the delay lengths and gains to avoid the 0-length lines accumulating unattenuated copies of the signal for the early reflection output.
