I'll upload the WAV to your file section then Bryan.
The 1st half of the WAV file is normal unprocessed audio, a guy then a gal.
The 2nd half of the WAV file is the same two people but after being encoded then decoded by AMBE chip.
The womans voice is fine, but the guys voice gets somewhat changed in the process. Appears to happen with just about any AMBE+2 rate setting. Not tried the AMBE-2000 or AMBE-1000 rates though, only tried the AMBE-3000 rates.
