[ALAudio] - HRTF should not affect 2D sources like music and GUI sounds.

Post by スマイル・ドラゴン »

I don't know if this is something that should be brought up with OpenALSoft developer(s) but the HRTF functions should only be applied to 3D sources, not 2D sources like music and GUI sounds.

If possible is there a way to "blacklist" the music and such from being filtered with the HRTF function?

The problem basically breaks down that [url=http://kcat.strangesoft.net/openal-extensions/SOFT_HRTF.txt]ALC_SOFT_HRTF[/url] works on a global scope, so there is at least no direct way of disabling it per source.

However, one could try to hit a path in the OpenAL Soft implementation which either disables or reduces the HRTF influence on the music, Smirftsch or I should ask Chris about it.

The only thing in the Source I see at first glance is that one could try to actually set a non zero AL_DIRECTION for the music source and see if that helps.

If it's possible to give the music a "neutral" AL_DIRECTION that wouldn't be affected by the default HRTF filters, that would work. A patch idea to OpenALSoft itself would be a good idea if you're in contact with the dev.
