Add support for (custom) HRTF #303

Open returntoreality opened 1 year ago

returntoreality commented 1 year ago

Having a HRTF would allow more accurate hearing of the sound origins. OpenAL-soft allows supplying a custom HRTF to fine tune the HRTF to your own head.

This might be related to #42.

This needs to be implemented first:

Does hrtfapo support custom HRTF though? From what I've seen, it just loads some binary/encrypted HRTF files that sound awful (I think it's what Windows Sonic uses) from the system folder and I don't know if they can be edited/replaced (maybe buying and selecting Dolby Atmos for Headphones, its personalized HRTF beta or DTS Headphone:X)

apparently XAudio 2 could be capable of 3D audio. I just found out that the HRTF files I mentioned on my previous message aren't just Sonic's but also XAudio 2 HRTF XAPO's. If I rename "C:\Windows\System32\DefaultHrtfs.bin", Spatial audio sample prints an error and Managed XAudio2 Hrtf Test as well as Spatial Sound tests here refuse to run. https://github.com/kcat/openal-soft/issues/586#issuecomment-1399231118

Also, didn't FAudio already support OpenAL Soft output at some point or did it replace it in FNA? And would you happen to know the reason why Unreal Engine ~4.24(?) onwards would break X3DAudio HRTF? It allowed adding 3D HRTF on older builds by replacing x3daudio1_7.dll, but apparently there was a big change and I noticed FAudio was eventually implemented, unless there's a way to bring back X3DAudio in newer UE builds or I'm missing something 🤔

FAudioDevice wasn't eventually implemented, it was always there to begin with (hell, it was there 15 years ago). With the same token the libsceaudio3d/libAudio3d backend should have something to do with Aureal, lol. And then, UE4 has the source available.. it should be a pretty mechanical process to bisect the culprit.

Never, you are perhaps thinking of wine implementing xaudio2_7 on top of openal before 4.3.
