I was wondering if someone could help me identify these sounds in the quiet passages of these files. It sounds to me like a chirping, or perhaps a squeaking, and is present and noticeable in nearly every quiet passage.

The first sample is from the start of a song that is operatic and quiet. The second sample is the ending of the same song. I've included it, as it is much closer to the peak of the track, to give a sense of how audible these sounds are.

My skill in iZotope RX2 is limited and I can't seem to figure out how to remove the sounds altogether.

@mzil: the rumble escalates at about that mark because I was performing a noise reduction in the beginning to try to isolate the offending sounds a bit better. The TT is a belt-driven Pro-Ject Debut III (USB) with a typical wall wart power supply. As the preamp is built into the table, I would not expect to be able to try the manual method you suggest.

What I could do is experiment with a different wall wart (and return it when I'm done for a refund...because I'm a prick like that laugh.gif )

@Apesbrain: I hear the chirps on most other LPs. With a bunch of rock and metal that doesn't have quieter interludes and/or outros, I probably just silenced between songs during processing and now I don't hear them in the digitized CD-R versions.

I wish I could find and isolate the sounds then I could use them as a noise sample. Problem solved. ...but I'm basically an amateur using professional-grade software. (And probably a less than ideal TT.)
