Is transcoding a wav file something that I should try to avoid? I have my files encoded as 16kbit, 8000hz, mono files, yet still in the logs I see:
2009-05-27 11:55:18 [DEBUG] switch_ivr_play_say.c:1084 switch_ivr_play_file() Codec Activated L16@8000hz 1 channels 20ms
2009-05-27 11:55:18 [DEBUG] switch_core_io.c:649 switch_core_session_write_frame() sofia/internal/5853297721@64.24.35.78 ([email]sofia/internal/5853297721@64.24.35.78[/email]) receive message [TRANSCODING_NECESSARY]


I have to think that not transcoding would be easier on the server, yet I don't know why it needs to transcode the audio file if it is, I think, already in the correct format for that codec...

Chances are those wav files are L16 either way its not an issue to transcode those... now if you were transcoding 48k to 8k all day long then I would worry but I think you're looking for savings in places where it doesn't matter in FreeSWITCH.
