In this specific case, I'm using g711, but can have either a-law or u-law but the service that requires the recording understand only a-law, at the moment I'm using ffmpeg to convert after the call ended, and then send it to that service.

as far as I understand, FreeSWITCH chooses the WAV parameters which 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.

Thinking in learning better the source code, and might create my first patch to FS :)

Hello,
I could not find any documentation on this subject. I require to have a recording of an a-law wav file (RIFF (little-endian) data, WAVE audio, ITU G.711 A-law, mono 8000 Hz).
Can I set a variable that tells the record command what type of codec to store the file with ?
I know how to convert a normal wav recording into it using ffmpeg (for example):
$ ffmpeg -i 0.wav -ar 8000 -ac 1 -acodec pcm_alaw 0-alaw.wav
But I wish to avoid it, if I can use the record app, or use the uuid_record API for it.
Thanks, Ido
