    Curious to hear thoughts on odd rip and poor quality results...

    I ripped an Infected mushroom album which ended up having some corrupted sounding audio, I go back to the log and noticed some tracks were ripped with different pressing offsets and some were not able to be verified with AccurateRip etc...

    Wondering if there is any gleaming reason as to why tracks on the same album would have been ripped differently like this... Shown below is the log... Thx!

    Track 6 seems to be one of the worst with corruption and even has the characteristic sound of a scratch on the disc surface that you hear when you rip without error checking... Track 7 starts with the ticking of a scratch as well.. I'll have to dig up the disc and inspect; I filed it away confidently when I remember seeing all secure tracks and I thought it was a new CD...

    Almost certainly the drive lost tracking on the cd between track 9 and 10, the remaining tracks were ripped with an offset.

    Re: Curious to hear thoughts on odd rip and poor quality results...

    The “Secure” means that there is likely nothing dBpoweramp can improve using this drive. It reads the same signal over and over again, be it right or wrong. (Wrong in this case.)

    I put all those aside to rip with a different drive. If you do, then chances are it will show up with all sorts of errors which makes it look worse than this – that is likely only because it detects and reports better (I bet a drive with C2 error reporting, will flag lots of issues).

    I have re-ripped a few which have scratching sounds. Very few have come through “Accurate”, but some certainly have improved a lot (meaning, getting rid of many of the errors).
