hi

i trade bootlegs and don't like receiving mp3 sourced bootlegs. Is there a sure fire way i can analyze the CD to tell if it is mp3 sourced. For instance, if i extracted one of the tracks to wav and did a frequency analysis in Cool Edit Pro 2 would that show the frequency clipping etc. Any help is appreciated.

Another thing to consider: if a show was recorded with a DAT at 32khz, the frequencies will cut off at 16. So a cut at 16khz isn't always a 100% reliable clue.

Sorry to bounce an ancient thread, but...

Is just my imagination, or was the some time ago (perhaps a year or so?) a software introduced on this site which was used to analyze audio/cd content and "guess" if the audio has been lossly compressed at some point of production?

I have this feeling that I saw this kind of program some time ago, but I am now unable to find it. The search terms just don't cut it:" mp3, lossy, compression, etc.".

Anyone recall this one? I want to wipe clean my CD-R collection of lossy stuff.

Sure. It's auCDtect (command line, freeware)/Tau Analyzer (shareware, GUI-based).
