How to get HRTF sound on Linux

Solution 1:

I managed to get a system-wide solution!

Several steps:

1. Create a sink

pacmd load-module module-null-sink \
sink_name=SantaClaus \
sink_properties=device.description=SantaClaus

2. Set it as default (can be done using pavucontrol)

pacmd set-default-sink SantaClaus

3. ffmpeg (see the doc to output to pulseaudio)

ffmpeg \
-loglevel error \
-f pulse \
-i SantaClaus.monitor \
-af "sofalizer=sofa=/path/ClubFritz9.sofa" \
-f pulse \
-name "3D Audio" \
"3D Audio"

4. Use pavucontrol to select the output of ffmpeg (named 3D Audio), choose your headphones or speakers
