# Acoustic echo cancellation for VoLTE speakerphone calls (journal/ims.md s43).

# Creates a virtual pair: ec_sink (play here; forwarded to the speakers and
|
||
|
|
# used as the AEC reference) and ec_source (mic with the speaker signal
|
||
|
|
# subtracted, WebRTC AEC). capture/playback are pinned to the hardware nodes
|
||
|
|
# so making ec_* the defaults cannot loop the module into itself.
