ALC_EXT_EFX and ALC_SOFT_HRTF

[ompadu]

Hi,

Is there any chance of these two extensions getting implemented?

• ALC_EXT_EFX provides multi-zone reverb, sound occlusion and obstruction (simulating sounds being behind doors or walls), and atmospheric air absorption.
• ALC_SOFT_HRTF provides binaural (HRTF) rendering. When used with headphones, this provides an unparalleled sense of 3D sound positioning.

Thank you

About HRTF, found an interesting example code that rotates a sound around the listener, that helped me understand the effect.

I think for HRTF in particular it would be best to split it in a separate issue which is support HRTF since OpenAL is intended for 3D positional audio, it's a relevant feature. I somewhat understand the math involved, but not really much how it would be implemented in this project in particular, since it's a single c file I don't understand much how to organize this functionality in the code itself - perhaps this would be a different codepath in the existing non-hrtf positional audio?

(like, here:

mojoAL/mojoal.c

Line 1750 in 8e392e2

gain = calculate_distance_attenuation(ctx, src, distance);

)
