Comment (by maxmanus):

 Ok, but when I write just -b it does show as constant bitrate in
 mediainfo.
 If -b:a 320k it shows as variable. I want it to show as constant. No way
 to fix this?
 I'm using qaac now because of this, but seems buggy when muxing together
 after with ffmpeg.

 Replying to [comment:3 Balling]:
 > Neither of those produce true constant bitrate, you need
 -bit_rate_tolerance 0 option. b92af7b64e7acd015aea3ae1da2228c5a7e677bf

 data, but bit_rate_tolerance 0  has bugs
