Algorithmic solutions
Unchirp seeks to solve the problems caused by lossy codecs and the many DSP processes that make use of Fast Fourier Transform. These problems include a variety of artefacts such as musical noise, high-frequency modulation and loss, transient smearing, and overall 'blurring' due to low localisation in the time domain.
Unchirp identifies the causes of artefacts and applies proprietary processing to make noise, chirping, etc disappear. By utilising two individual, yet simultaneously available algorithms Unchirp effectively offers musical noise reduction and de-chirping. Both algorithms are distinct from one another, and offer a unique technological approach, thus featuring different sonic qualities. Because each algorithm is unique, each has its own breakpoint curve editor for frequency-dependent processing.
Transient bypass and synthesis
To preserve a high-quality mix even with extreme settings Unchirp allows for the bypassing of transients by the included algorithms. Furthermore, Zynaptiq has added frequency dependency to the bypass threshold, and frequency-dependent transient attenuation and boost, so you retain comprehensive control over which frequencies are affected and to what degree.
Often, transients can be compromised by Fast Fourier Transform processes, such as lossy encoding, or by excessive dynamics processing. Unchirp features 'Transient Synthesis' to recapture the nuanced details in your mix, and a sync function synchronises processing to your signal's transients, adding overall clarity and coherence.
Treble boost
Audio that is encoded with a low bit rate is often subject to a 'dead band' in the treble range. In this instance, regular eq can't help because there is nothing to boost, but Unchirp offers two ways to recover that treble with its treble boost circuit. The first way is a psycho-acoustically optimised enhancement that equalises frequencies in such a way that it implies frequency content in the dead band to the listener. The second way is through an exciter that synthesises new harmonics to fill the gap left by the dead band.
As with Unchirp's other features, treble boost can also be used to add shine and vibrance to your audio.
Other features
Amongst its more pronounced features, Unchirp also has a variety of workflow features to help you get results faster. These include an output limiter to allow for unsupervised batch processing without overs, an I/O difference function to quickly hear what exactly you're removing, and frequency-dependent processing for all key parameters using breakpoint curves with snap-to-zero and copy/paste functionality. Furthermore, Unhchirp features and a preset manager that writes presets that you can use across all platforms and format.
