Hello Dennis Guse, George Joseph, Anonymous Coward #1000019, Matthew Fredrickson, Joshua Colp,

to look at the new patch set (#13).

Change subject: Binaural synthesis (confbridge): Adds binaural synthesis to bridge_softmix.
......................................................................

Binaural synthesis (confbridge): Adds binaural synthesis to bridge_softmix.

Adds binaural synthesis to bridge_softmix (via convolution using libfftw3).
Binaural synthesis is conducted at 48kHz.
For a conference, only one spatial representation is rendered.
The default rendering is applied for mono-capable channels.
A set HRTFs is included as header file
(bridges/bridge_softmix/include/{impulses.h,hrirs.h}).
HRTFs were taken from here:

data/impulse_responses/hrirs
