What is that chirp you hear in older mp3 rips?

Every now and then I pass through a music track I acquired years ago that has a little digital chirp or irk randomly in it. It's not just one, but many tracks from the old days of mp3 ripping have this aural watermark. Is it some program that inserted it? The way the file was transfered? Anyone else notice this?
 
What do you exactly mean by "mp3 ripping"? Do you mean importing your songs from a CD or the quality after a download?

I do notice some differences in sound quality, but the other way round. In all these years that I've got my iPod and KOSS headsets with all the new fancy Feeder albums and whatnot, still nothing has been able to beat the sound of Pink Floyd through these headsets. I think it may just be based on the quality of the instruments (and the wide range of instruments used) and the software when the recording happened?
 
A slower computer and/or a sloppy MP3 encoder can hiccup if the encoding process is interrupted by something else. My MP3 CDs in the car have also picked up such hiccups from getting scratched by road bumps.

I also encountered the phenomenon when ripping audio data from a scratched up PSX disc.

Yup. It is was ripping at slower speeds is a good idea if the disc is damaged. I have many older Mp3s that I ripped in my infancy of Mp3 stuff, and didn't put enough thought into the process. Going back now, I've had to delete a lot of the stuff and then download new copies (which is legal, since I did buy the CD :p)
 
Yep, a rip error. A bit of digital gibberish, which the player doesn't know from music. Usually a buffering problem, like an overflow when an encoder couldn't keep up with the input. Sometimes a CD scratch will do something similar.
