Zynaptiq has announced the release of UNCHIRP, a codec artifact removal and transient retrieval effect plug-in for Windows and Mac.

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.

UNCHIRP features

  • Suppression of high frequency “chirping” artifacts.
  • Reduction of “musical noise” artifacts.
  • Transient Synthesis to augment or replace smeared, over-limited or otherwise compromised transients.
  • Psycho-Acoustically optimized Treble Boost circuit with Enhance and Excite modes.
  • Break-Point Curve Editor based frequency-dependent processing.
  • Side-only algorithm mode for working with joint-stereo encoded material.
  • HD algorithm mode for increased quality processing with higher CPU load (off-line processing recommended).
  • SYNC parameter allows processing to be synchronized to signal transients for increasing clarity.
  • Output limiter for unsupervised use in batch processing applications.
  • Highly time-efficient workflow and UI.

UNCHIRP for Windows and Mac (VST/AU/RTAS/AAX/AudioSuite) is available for purchase for $399 USD / 369 EUR (incl. VAT in EU).
