I agree, this track is clearly compressed. Very very sad, in my opinion. This would be a no-go for me, especially if I'd have to pay 15 Euros for it.
Indeed, the track could originate from a 44.1- or 48-kHz MP3. Looking at .halverhahn's image upload and my Audition plot, I can see blocking with a length of around 1100 samples (i.e. roughly 2x576 or 2x576x(44.1/48)) and band-wise gating during the quiet passage around second 19 - 22. The borders of these bands are at around (as measured visually in Audition) 6.5ish, 8.0ish?, 9.6, 11.5, 13.8, and 16 kHz. Does anyone have the scale factor band borders for MP3? Do they coincide?
Actually, exporting to 192-kb CBR MP3 in Audition 1.x gives a spectrogram very similar to the upload.
Update: Found the scale factor band tables here. Sorry, couldn't wait
Tables.hs
tableScaleBandBoundLong 44100 = [ 0, 4, 8, 12, 16, 20, 24, 30,
36, 44, 52, 62, 74, 90, 110, 134,
162, 196, 238, 288, 342, 418, 576]
tableScaleBandBoundLong 48000 = [ 0, 4, 8, 12, 16, 20, 24, 30,
36, 42, 50, 60, 72, 88, 106, 128,
156, 190, 230, 276, 330, 384, 576]
If we take the 48000 table, we get:
24 kHz * 156 / 576 = 6.50 kHz
24 kHz * 190 / 576 = 7.92 kHz
24 kHz * 230 / 576 = 9.58 kHz
24 kHz * 276 / 576 = 11.50 kHz
24 kHz * 330 / 576 = 13.75 kHz
24 kHz * 384 / 576 = 16.00 kHz
Bingo! It's a 48-kHz MP3 decoded to 44.1-kHz. Probably 192 kbps. Ouch...
