Looking at the libsndfile API this should be doable but I would need to read up on it more, If you require this feature email consulting@freeswitch.org for a quote on adding this functionality.ThanksOn Tue, Nov 11, 2014 at 8:33 AM, Brian West <brian@freeswitch.org> wrote:If he wants to record without transcoding it is the only viable way to do so currently via mod_native_file. The task was a nice exercise as it exposed a nice little segfault in the stop record. (FS-6980).I fully understood what he wanted, and that it wasn't possible, offering up what we currently can do with mod_native_file.On Tue, Nov 11, 2014 at 7:49 AM, Ben Langfeld <ben@langfeld.co.uk> wrote:Brian, was this answer supposed to be to some other question?

Now you'll be all set to waste more time dealing with two files vs the single wav file.

Thanks

are matching the current channel sampling frequency and codec. For
example, if you record a G722 call, you would get a 16kHZ WAV file.
Forcing it into one specific encoding would add real-time CPU load. I
think it's still more preferable to run a post-processing job in low
priority -- this way you ensure that the ongoing calls get the best
serving.
You can easily catch the event of call ending and trigger the
conversion job, by listening to the events via ESL connection.
