Replying to [comment:65 klaussfreire]:
> Yes, bit_rate in that case holds the default of 128kbps. Psy does the
same, but it works well since that's considered to be AAC's transparent
rate.

AAC is not transparent in 128kbps stereo, although Apple used to advertise
that way. http://d.hatena.ne.jp/kamedo2/20111029/1319840519
