Chorus D is an audio unit effect inspired by a well-loved classic chorus stomp-box. HOW IS IT DIFFERENT FROM OTHER CHORUS EFFECTS? It's more subtle. It has a stereo pair of pitch-shifters, one shifts up and the other down. Every few seconds, the two pitch shifters trade places: the high one goes low and the low one goes high. Unlike most other chorus effects, the pitch-shift amounts stay constant rather than oscillating up and down. For that reason, you don't hear the wavy pitch sound that other chorus effects make. At low settings, you can put it on a track to widen the stereo image or thicken up the sound and listeners may not be able to identify that they are hearing a chorus effect. WHY ONLY SIX BUTTONS? The original hardware that inspired this design had only four buttons and four presets, one for each button.* The simplicity of the controls is one of the reasons the effect was so well-liked: all four presets sounded great. With six buttons you get tones ranging from very subtle to clearly audible, and all of them are tasteful and useful. This effect makes only one type of sound but it's a unique sound that you don't get from other chorus effects. IS THIS AN EXACT CIRCUIT MODEL OF THE ORIGINAL HARDWARE EFFECT? No. We listened to the original and studied its design but then we built an effect to please our own ears. It sounds similar to the original but the design is unique. ************************************ Note: this is an audio unit plugin. It does not process audio as a standalone app. *Later on customers figured out that they could get some other settings by pressing two buttons simultaneously or forcing all the buttons off. We are using six buttons to get wider variety of sounds rather than expecting customers to discover those secret features of the original hardware.

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.
