Is there an updated guide on how to split recordings of RX and TX into two different channels and then join them together as one stereo recording? Trying to transcribe my recordings, and the results are much better when the channels are split.
All the previous guides from 2021 and before don’t seem to work anymore on freepbx 16.
Asterisk stable versions released 2024-11-21T07:00:00Z – 20.11.0, 21.6.0 and 22.1.0 – all got a new option which might help you, but some custom dialplan would be needed until FreePBX support is added:
app_mixmonitor: Add ‘D’ option for dual-channel audio.
The MixMonitor application now has a new ‘D’ option which
interleaves the recorded audio in the output frames. This allows for
stereo recording output with one channel being the transmitted audio and
the other being the received audio. The ‘t’ and ‘t’ options are
compatible with this.
