I found a buzz sound in the CD titled 'Respighi- Ancient Airs and Dances' by TELARC digital
which has a short buzz sound in the track 5 (Suite No.2 - I. Fabrizioliarda, saltarello e canario)
buzztime=2:27

The sound is a unplesant harmonic. There is also a constant 21.6KHz peak that Idon't know what it is
I discovered that accuraterip was happy, not my system problem.(seems to be master problem)

I eager to know where did the harmonic beep and 21.6KHz peak come from? concert hall? machine? cables? mixing?......
thanks guys

TELARC record at higher sample rates, and down convert for CD.

I think I've read reports that they've experimented with downsampling without an anti-alias filter. If that's true, those "harmonics" could have come from anywhere, and originally been at much higher (i.e. completely inaudible) frequencies.

Strange they didn't catch it in QA/testing.

EDIT: I reckon it's a pigeon - no way to "fix" that (well, not now anyway!).

Cheers,
David.

Such a buzz spoils the music.
any more replies?
