This is a build of DSOAL used in the mod "True 3D Sound for Headphones" for Fallout: New Vegas with a custom config made to imitate vanilla SADX as close as possible.

To add this to SADX, extract all files in the archive to your SADX main folder (where sonic.exe is).

You can edit alsoft.ini to enable 5:1 audio support, HRTF algorithms etc. For possible options, see this file: https://github.com/kcat/openal-soft/blob/master/alsoftrc.sample
