Hello there, Pierpaolo from Dropbox here.

You correctly guessed that we picked libfaac as a safe option for compatibility. I never tried out aacplus and sounds indeed interesting so we'll likely try it out soonish. Our target rate is a bit higher than those you mention though. For audio, we target 32kbps at low quality layers and 96kbps at higher qualities. Couple of questions for you: - how does aacplus works at these rates? - what compatibility issues can we expect if we were to try it out?




HE-AAC (AAC+) sounds surprisingly fantastic at 32kbps.
