A tool by Microsoft, tells you everything about the contents of an audio file.


Removes wow and flutter from musical recordings – whether on tape, compact cassette, wax, shellac or vinyl. Capstan detects wow and flutter by analyzing the musical material itself, so the medium is of no relevance.

DeGlitch is designed to detect and correct isolated bad samples in digital audio files caused by ripping damaged CDs or discs that do not meet the CD standard (i.e. copy protected). These errors are generally heard as clicks, although they can also occur in bursts that sound more like crackle. DeGlitch will not work at all on the clicks found in vinyl rips (which span many consecutive samples) and will not work as well with audio that has been compressed (except lossless). Its algorithm will also fail in error bursts where more than 1/3 of the samples are corrupted, although these will normally occur only with deeply scratched CDs.
