Asterisk Team commented on ASTERISK-26292:
------------------------------------------

Thanks for creating a report! The issue has entered the triage process. That means the issue will wait in this status until a Bug Marshal has an opportunity to review the issue. Once the issue has been reviewed you will receive comments regarding the next steps towards resolution.

A good first step is for you to review the [Asterisk Issue Guidelines|https://wiki.asterisk.org/wiki/display/AST/Asterisk+Issue+Guidelines] if you haven't already. The guidelines detail what is expected from an Asterisk issue report.

Then, if you are submitting a patch, please review the [Patch Contribution Process|https://wiki.asterisk.org/wiki/display/AST/Patch+Contribution+Process].

> 3D-Audio is an interesting for telephone conferencing.
> In a development and research project at TU Berlin, we enhanced Asterisk's 
> conferencing bridge with binaural synthesis.
> Technical Details: 
> * Modified internal signal processing to be capable handling interleaved audio (channel, translate)
> * Extended confbridge (precisely bridge_softmix) by binaural synthesis (basically added a convolution engine using libfftw3) 
> Note: confbridge remains capable to mix for mono channels (default mixing) and binaural synthesis in parallel
> Practical details (can be changed):
> * Required HRTFs are at the moment included as header file
> * Confbridge is at the moment only running with binaural synthesis at 48kHz
> * Only one 3D-Layout per confbridge is rendered (all participants receive the _same_ spatial representation; one's own signal removed)
