[Freeswitch-users] Recording with Native File PCMU

[Anthony Minessale]

The processor power saved is negligible between PCMU and raw PCM and not
worth the fuss.
If you didn't decode the audio first you would not be able to mix the stream
to produce a single file.
So if we went to the trouble of making native media bugs to be able to do
that you could barely use them so it would not be worth the 5k or more
bounty to develop that functionality.
