UNCHIRP is a plug-in for removing the most obnoxious artifacts associated with lossy audio encoding and other FFT based processes, such as spectral de-noising. Reduce musical noise, suppress high frequency chirping (also known as underwater sound, warbling or the tweeties), fix transient smearing, and restore lost high frequencies - UNCHIRP does it all in one go. If you need to salvage poorly encoded music, speech that has gone through a low bit rate uplink, material that has been de-noised too strongly, or footage recorded with consumer mobile devices - or if you simply want to add contour and vibrance to already great sounding recordings - UNCHIRP is your (only) friend.
