UNCHIRP Black Friday pricing is 63% off, so Zynaptiq's artifact-removal plugin costs $99 until Nov 22, 2026.
UNCHIRP removes the artifacts that lossy encoding and FFT-based processing leave behind, such as the ones from spectral de-noising.
The maker says it handles musical noise, high-frequency chirping (the underwater, warbling, "tweeties" sound), smeared transients and lost highs in a single pass.
Zynaptiq's explanation: lossy codecs and many de-noisers rely on the Fast Fourier Transform. That method causes musical noise, high-frequency modulation, transient smearing and a blurred sense of time.
It names poorly encoded music, speech from a low bit rate uplink, over-denoised material and consumer mobile footage as typical jobs.
The maker also points to already good recordings, where it can add contour and vibrance.
There are two algorithms available at the same time: Musical Noise Reduction and Dechirping. Each one has its own breakpoint curve editor for frequency-dependent processing.
Transients can be bypassed, so extreme settings still sound natural. The bypass threshold and the transient attenuation or boost both depend on frequency.
Transient Synthesis can replace transients damaged by lossy encoding or heavy dynamics processing. The SYNC parameter ties processing to the signal's transients.
Low bit rate audio can have a dead band in the treble, and a regular EQ has nothing there to boost. Enhance uses equalization tuned so the listener perceives content in that band. Excite synthesizes new harmonics to fill it.
The plugin runs as AU, VST 2.4, VST 3 or AAX Native. On Mac that means macOS 10.15 or newer, on Apple Silicon or an Intel CPU with at least 2 cores. On Windows it means Windows 10 or newer with a 64-bit host.
Activation needs an iLok account and an internet connection. A first-generation iLok is not supported.
Zynaptiq says its plugins use a lot of CPU and recommends a buffer size of 512 or ideally 1024 samples.
UNCHIRP also ships inside the ZAP Bundle with UNVEIL, UNFILTER and PITCHMAP.
Yes. The UNCHIRP Black Friday deal is 63% off, which brings Zynaptiq's plugin to $99 until Nov 22, 2026.
It targets artifacts from lossy encoding and FFT-based processing: high-frequency chirping, musical noise and transient smearing. The maker also lists lost high frequencies, which its Treble Boost circuit tries to restore.
UNCHIRP comes as AU, VST 2.4, VST 3 and AAX Native. It needs macOS 10.15 or newer, or Windows 10 or newer, with an iLok account and internet connection for activation.
Yes. Besides the single plugin, UNCHIRP is included in the ZAP Bundle with UNVEIL (reverb removal), UNFILTER (adaptive equalization) and PITCHMAP (polyphonic pitch processing).
