My IVR prompts are in .WAV format.

Refering to your previous post :

You should strive to have prompts available in all the channel encodings
actually used by your system. I have systems that only use ULAW, so all of
my prompts are encoded as ULAW. (Sometimes I "cheat" and use WAV files
since they are easier to work with and transcoding from WAV to ULAW is
"cheap.")

Can I convert my .WAV IVR greetings, MOH and other recordings into G729
format to prevent transcoding and hence CPU usage ?

Thx
