lossless checker?

If you mean finding out if a lossless file was converted from a lossy format, check the spectrum (FFT) of the audio, if there is a sharp high frequency cut-off (e.g. typically at 16 kHz for 128 kbps MP3), or bands of treble are missing at times, then it is probably lossy.

Has been asked at least two or three times before. Use the search.
