[Asterisk-Users] OT: mixing monitor files to stereo wav
Hi, i am looking for a tool to merge the two wav files of a monitored call into one. soxmix does that well but actually merges the two channels. I would prefer a solution that creates a stereo wav file of the two mono files so you have the called party on one (e.g. left) channel and the calling party on the other (e.g. right). I can do this interactivly using audacity but i am looking for a tool to automate this. Anybody knows a piece of open software that supports this? Thanks in advance Stefan

No one was awake on the IRC channel to help out so hopefully they'll release a new version soon that has the necessary bits implemented.
