I also experienced this when encoding AAC, so I stopped using AAC.
I'm not using the very latest ffmpeg, so I didn't bother reporting the
issue, and it's been on my To-Do to check the latest version for a
while. Been busy and all. Anyway, I thought I'd say "me too", and add
that it does seem related to the AAC encoder, because it only happens
It's not so much noise, as "clicks". Probably some buffer alignment mishap.
