Call Recording file format(s)
Please help with my call recording question. If you know of a good link/doc with this info, please pass it my way. How does call recording work on Freeswitch? Is the recording saved by default in a .wav file? If so, is it always saved as .wav or can I configure in what format I want to save the recording? I noticed that .wav, .gsm, mp3 and .ogg formats are supported (http://wiki.freeswitch.org/wiki/Weekly_Conference_Call#Past_Calls). Are recordings saved in different formats in real time or converted late? Are they converted at the first request and saved for future use? Is this design decision left to the FreeSwitch user - i.e. if converted later, do I need to implement the conversion myself? I scanned through some older questions and sox and lame are mentioned. My recordings will be around 800K in wave format (raw data uLaw 8b/8kz stereo) so I am not looking to save space but I am getting the request from the front end guys to provide the recording in .mp3 format. Thank you, A.C.
http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_record_session#Possible... Encoding is done on-the-fly, and is determined by the file extension. There's the option of post-processing using tools like sox, but native encoding in various formats (including mp3) are supported.

All things being equal, we just save as a wav and then do post-processing to convert it to the flavor du jour desired by the end users. One advantage of doing this is that you have the option of off-loading the file post-processing to another system if you so choose. Between sox and lame you've got all the free tools you need to convert to whatever file format your circumstances dictate. -MC On Tue, Jun 19, 2012 at 10:39 AM, Adelia C. <hexade@hotmail.com> wrote:
