Comment (by cehoyos):
Replying to [comment:282 Kamedo2]:
> I think we should redirect users to 8k if the -b:a set is less than 8k.
This is not done for any other codec.
> The ancient FFmpeg set bitrate by the unit of kbps
I just tested a five year old version and the unit is bps.
> so a novice user of modern FFmpeg may set bitrate like -b:a 128. If
something sounds, the user may notice that the bitrate set is too low.
Current FFmpeg prints a warning.
Since this is unrelated, please don't let this delay the patch.
