Cd Audio Fault

Hello
I have some CDs with audio written to BASF EMTEC discs.
These have become corrupted. The audio plays, but has a constant almost cyclical noise embeded in the audio.
The disks have many errors, but the audio is continuous without any mutes or glitches.

Here is a sample

Can anyone identify what the cause might and how it might be corrected. I have tried Exact Audio copy to try and extract clean audio, but with no success.

The disks have many errors, but the audio is continuous without any mutes or glitches.

When I listened, I heard lots of mutes and glitches :confused:

I also viewed the raw WAV file with a hex editor and could see many mutes/holds in the data.

Have you tried listening to these in multiple CD audio players? You might also try ripping at the slowest possible speed and with various drives/software.
