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

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 patche

Apologies for not responding quicker to your e-mail - I've been on

Hello,
the cleanup and splitting up into individual patches took some time,
but those are now submitted: Asterisk-26292 [1].
The issue with this patch set is that it _requires_ libfftw3.

we adjusted the patch set (fftw3 is now a ifdef-ed).

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.

Hey,
last week we started reworking the major patch [1] and could not solve one
issue.
At the moment, the softmix_bridge determines if interleaved stereo can be
written by querying ast_format's attribute data if OPUS is used ([2]):
```
struct opus_attr *attr = ast_format_get_attribute_data(format)

Thanks Joshua,
just to be clear that I understood it correctly.
1. We would extend ast_format [2] with the additional field `uint
channel_count:1`
2. We would modify `opus_parse_sdp_fmtp` [1] to set
`cloned->channel_count=2`on the `ast_format` to be returned.
Would this be acceptable or is this c

The final three patches are now on Gerrit:
* https://gerrit.asterisk.org/#/c/4654/
* https://gerrit.asterisk.org/#/c/3524/
* https://gerrit.asterisk.org/#/c/3525/
4654 fails to build as it requires libsndfile (which is not present to

Finally, we will port our opus changes (ie.

Here are just the steps to setup the binaural synthesis and the required
stereo-capable OPUS module:
