Context

Positional audio

Description

Mumble already tries to convey the illusion of sound coming from different directions by

Making it actually come from different directions in a surround-sound setup
Using interaural delay

but actually there is even more to how humans perceive the direction of a sound:

The frequencies of the sound of the opposite ear are changed due to the head acting as a frequency filter
The phase of the audio between the two ears is usually different
the volume of a sound will change depending on which ear it receives it (again, due to the head blocking the sound's path)

Mumble component

Client

OS-specific?
