Since all patches are now merged, this will be the last eMail from me on this thread. Here are just the steps to setup the binaural synthesis and the required stereo-capable OPUS module: ``` git clone http://gerrit.asterisk.org/asterisk git clone

Hey guys, we continued working on our largest changeset: https://gerrit. asterisk.org/#/c/3524/ Besides the copyright of HRTFs (still under investigation from our side), the only issue on our side is the introduced `settings_lock` (defined in bridge.h:254). This lock is used in addition to the

This is getting to be an old thread, but the "magic" for adding multiple changes is as follows: * use your working branch * make changes * git commit -a --amend * save... * git review This way, the same branch, with the initial commit, will be preserved along with the same change ID. If you

Re: [asterisk-dev] Asterisk goes Spatial Conferencing: the STEAK project

Then lets get started. Due to the relatively large number of changes, we will split them up into individual patches: 1) Support for interleaved stereo (mainly softmix and struct channel) 2) Extension of confbridge with binaural synthesis via convolution (if channel supports stereo) For the

Hello, spatial audio for telephone conferencing has been proclaimed as a silver bullet for speech-based telephone conferencing. For research, we needed a _production-ready_ system that provides a centralized conferencing bridge being able to provide binaural synthesized spatial audio (i.e., for a
