Comment (by Kamedo2):

 Another bug, typically happens when hi-hats are present. The sound
 disappears for about 20ms.
 Short, but it's still audible and sounds like a annoying pulse.

 When these problems are solved, I'm going to conduct an extensive blind
 listening test, to assess sound quality of AAC encoders available from
 FFmpeg.
