This app is capable and complex FM synthesiser that can create rich and very strange sounds combining up to 10 sound generators. Every generator can be adjusted up or down from the main frequency almost without restrictions in range. There are 4 possible wave forms for the generator output and you can tweet the volume, modulation and add some tremolo effect. You can listen to the result sound while you are adjusting the new generator and just add it to the result when it sounds good. With the Sound Maker Synth you can also add reverb and then play it as a one voice synth using the one octave keyboard at the top. The app is very capable to create some strange and alien like pad sounds as some dubstep bass.

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.
