We've removed the 320kbps aac option for this, because it was exactly the same as the 192kbps option!
(It turns out that ffmpeg outputs files at the same quality as long as the command argument is above 175 kbit/s or so; aac appears to only do bitrate dynamically and it just doesn't need more than that to do max quality for a spoken word recording.)
