01Overview

UNCHIRP Educational Version targets the audible side effects of lossy audio encoding and FFT-based processing, including high-frequency chirping, musical noise and transient smearing. Zynaptiq says it combines two simultaneous algorithms, Musical Noise Reduction and Dechirping, with a Transient Synthesis stage and a Treble Boost circuit. Its feature set includes a breakpoint curve editor for frequency-dependent processing and an output limiter for batch work.

Artifact Removal and Transient Restoration

UNCHIRP is built for material that has been damaged by lossy codecs or aggressive de-noising. Zynaptiq describes it as a tool for salvaging poorly encoded music, speech sent over low bit rate links, and footage recorded on consumer mobile devices.

Transient Synthesis can augment or replace transients that have been smeared, over-limited or otherwise compromised. The SYNC parameter aligns processing to signal transients to improve clarity, and a Side-only mode works on joint-stereo encoded material.

Treble Boost and Workflow Controls

The Treble Boost circuit offers Enhance and Excite modes. Enhance is described as a psychoacoustically optimized equalization, and Excite synthesizes new harmonics to fill a band where the encoding has removed content.

Frequency-dependent processing uses break-point curve editors with snap-to-zero and copy/paste functions. An I/O difference function lets you hear exactly what is being removed, and an HD algorithm mode offers higher-quality processing at a higher CPU load, suited to off-line use.

05FAQ

Questions, answered

What formats does UNCHIRP Educational Version support?

It is available in VST3, VST2, AU and AAX formats. It runs as 64-bit software on Windows and macOS.

What do I need to run UNCHIRP Educational Version?

You need a compatible host that supports VST 2.4, VST 3 or AAX, processing audio as 32-bit float. Activation requires an iLok account and an internet connection. Zynaptiq recommends a playback buffer of at least 512, ideally 1024 samples.

Does UNCHIRP Educational Version use a lot of CPU?

Zynaptiq says its plugins use significant CPU because of their complex processing. The company recommends evaluating the free trial to check whether your system has enough resources.
