I would bet that may be a buglet, since G722 is clocked at 8k but really a 16k codec, Can you file a JIRA on that? On Wed, Oct 8, 2014 at 6:15 PM, Michael Collins <msc@freeswitch.org> wrote:

For those of you familiar with the fs_encode tool I have a question - I can run it on a G722 raw file (such as is produced when using tshark to extract the RTP stream) and it produces a perfect wav file at exactly half speed.

I'm using basic syntax: #>fs_encode raw_audio.G722 output.wav

Looking at fs_encode's options I tried using -r to specify the sampling rate, but that seems to apply to the input on the codec and anything other than 8000 produces an error.

Has anyone used fs_encode to decode G722 (or any other exotic codec) with success? I appreciate your input.

P.S. - doing #>sox slow_audio.wav normal_audio.wav speed 2.0 will "fix" the file, so I'm not totally dead in the water. I was just curious if I was possibly not using fs_encode properly. :)
