AFAIK, gsm is lossy, which is why it doesn't sound good.

wav, however, should sound great. What codec are your calls in? Are you recording many calls?

Check the load average while you are recording. If it's greater than the number of CPUs then probably your hard drives can't keep up. There are several options then, first let see if we can diagnose the issue.

Good day.
I'm trying to record all calls sent through my Freeswitch PBX.
The problem is that the quality is horrible. I've tried wav and GSM formats, and both are les than satisfactory.
I'm looking for something around the quality of the recent recordings of the Freeswitch conference. (I checked on the wiki, and couldn't find anything through search.)
Any information on the FS conference format or my configuration would be appreciated.
I've got:

<condition field="destination_number" expression="^(.+)$" break="never">
<action application="set" data="RECORD_TITLE=Recording ${destination_number} ${caller_id_number} ${strftime(%Y-%m-%d %H:%M)}"/>
<action application="set" data="RECORD_DATE=${strftime(%Y-%m-%d %H:%M)}"/>
<action application="set" data="RECORD_STEREO=true"/>
<action application="record_session" data="$${base_dir}/recordings/${strftime(%Y-%m-%d-%H-%M-%S)}_${destination_number}_${caller_id_number}.wav"/>
</condition>

Sincerely,
Brandon McGinty-Carroll
