|1||1||Interesting. I just confirmed this still happens. I'm working on the AAC encoder, so I think I'll take a look at why this happens. While working on AAC's rate control, I noticed similar issues when too many bits are assigned to too loud signals, and it does look like this could be the case (the signal is really powerful). I already added lots of failsafes for this case (on a patch that I'll be sending soon), but it doesn't seem to cover this particular issue in the attached sample. So I'll keep looking.
