My experience of AAC is that you tend to get a typically steep and almost complete drop at the top end of the spectral analysis, around 16kHz and then a little island of frequencies after that, whose range and depth is determined by the bitrate at which the AAC was encoded.

well it's really the SA that's most alarming. lossy encoding is the only thing that causes the zoomed SA to look like it's built from squares. Just because it's from Silvers doesn't mean it's lossless... there was a Metallica '86 show on EZT directly from silvers which was mp3-sourced a while back.

and thanks for the Audacity tips. it would be cool if they would add cue stops which could be on the boundaries or not and a splitting function someday.
