Nifty little program, good for spotting these idiots who like to transcode low quality mp3 to FLAC
FLAC especially 16/44.1 which is of CD Quality is 22.1khz

A lot of mp3 transcoded (providing the track actually reaches 22.1 in it's WAV form before being ripped originally to mp3) will show low results, especially anything under 320 CBR, most 320 will not be above 20.5khz where a V0 VBR can hit 22.1khz. 

So picking a high V0 maybe a little tricky, but picking a pathectic 128, 192 will be easy to spot as a line won't reach anywhere near 20khz.. 

Example of a 128 ~~ Transcoding this file back to a WAV or even a FLAC (FLAC and WAV are both Lossless where mp3 is Lossy) won't bring a miracle in sound quality at all, what you get is a oversized file with the sound quality of the original 128
