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.

That's interesting. I know little about what I'm looking at when viewing or trying to discern the ghost waveform. The file was recorded with a bit depth of 44.1. I upsampled it to 32/44.1 from VinylStudio's output options so I could tweak it in iZotope RX2 Advanced. The resulting samples were dithered back to 16 bits. I don't believe the sample rate was changed at any time.

The chirping or squeaking noises I hear are audible prior to digitization. I can hear them through headphones simply by playing the record through my home stereo. I've no idea what it could be.

EDIT: I guess I do see this ghost waveform you were talking about...
