You can use sox tool to split the channels after recording. It works very fast, so the delay should not be a problem. On Apr 18, 2015 10:31 PM, "Dmitry Saratsky" <simpot@gmail.com> wrote:

Hi all,

I have .wav file which was recorded by freeswitch in stereo mode a-leg to left channel and b-leg to right channel. now I want to play only one channel to caller using lua. sometimes left one and sometimes right one.

I can't find any documentation on playback or any other apps how to play only one channel...

Any ideas?

Thanks a lot! Dmitry.
