This compressor has the lowest total harmonic distortion of any plugin we have seen, including desktop units. At the heart of it is a unique envelope follower design that makes it possible to compress the signal without creating distortion harmonics. On the spectrum of compressor tone that ranges from "vintage analog" to "pristine digital", this plugin sits at the extreme end of low-noise digital clarity, but it is different from other low-noise digital designs because it doesn't use digital look-ahead. Therefore its response time is immediate, it adds no extra delay to the signal chain, and it works great for processing real-time performance effects. It uses no oversampling so there is no phase distortion or loss of high-frequency energy from anti-aliasing filters. It also uses no digital-style filters (FIR filters) and no digital look-ahead, so it adds no additional latency to the signal chain. Although it is not a model of an existing piece analog hardware, every component of its signal path is realizable in the analog domain. We think of it as a digital model of our ideal analog compressor: it could exist as an analog circuit but would be very expensive to build with physical analog electronic parts. The user interface is 100% scalable, designed specifically for iOS, so it looks beautiful at any screen size or orientation, from tiny portrait views in AUM on iPhone to the largest full-screen views on iPad Pro.

Kompresor is a versatile and powerful, yet easy to use, compressor. With several compression algorithms and processing modes under the hood, Kompresor is suitable for use on a wide variety of signals, on the mix bus, or for mastering. For the most transparent compression, ideal for mastering, use AUTO or "AUTO A" envelopes. Use PROGRAM envelope for an easy mix bus gluing effect. If you are after the classic style compression switch to feedback configuration. Select RMS detector for a smoother compression suitable for vocals, guitars, etc. Five processing modes allow you to go from the standard stereo (L/R) compression mode to more surgical modes like compressing the mid (sum) or side (diff) signal only, or compressing exclusively the left or right channel. To help you fine tune compression parameters, enable DELTA feature to monitor only the difference between the uncompressed and compressed signal. Last but not least, Kompresor has an external side chain input for those times when you need to duck one signal based on another one. Features: – Four types of compression Attack/Release envelopes SIMPLE, AUTO, AUTO A, and PROGRAM. – Five processing modes LEFT, RIGHT, MID, SIDE, STEREO – External sidechaining (only in hosts that support external sidechaining) – Very fast attack time - 0.01ms – Ratio up to 30:1 – Soft knee up to 50dB width – Feedforward and feedback configuration – Peak and RMS detectors – Sidechain high pass filter – Parallel processing – Monitoring only the difference between the uncompressed and compressed signal – Intelligent auto makeup gain – 4x oversampling to avoid aliasing – Plenty of factory presets to provide a starting point Kompresor is primarily an AUv3 effect. To use Kompresor as a plug-in, you will need an AUv3 compatible host such as Garageband, AUM, etc. Kompresor application is there to provide a user manual and a chance to use Kompresor with the microphone input. You can try Kompresor on a macOS or a Windows based machine by downloading the demo version of the plug-in (VST3, AUv2, AAX) from our website (https://www.shatteredglassaudio.com) and running it in a DAW of your choice. Sonically speaking there are no differences between the iOS and macOS/Windows versions of Kompresor.
