we experience some latency in the recording files even with PCMU-PCMU session to a stereo WAV file. i want to reduce the CPU load hoping to reduce this problem. would it help if do the ff?
1. save it in PCMU file. i can use sox at the end of the shift.
2. record in mono. does it help?
3. will record_session work w/ proxy_media=true?

tks for your help.
