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. stuart |

Heh, I came across a method quite by surprise... plug in some headphones, and unplug them slowly, until you hear a warble. Depending on the type of warble you hear, you can quite often discern between mp3's and normal uncompressed audio.
