*** Note: this is an Audio Unit Effect Plugin (AUv3) which requires a compatible host or DAW to work. *** Kosmonaut is Multitap Delay with a twist. In addition to adding echoes to your audio, it packs a bunch of extra tools to put your music in space: - Tape looper with with variable sound-on-sound decay level - 4-Tap Delay (placed in series for complex feedback loops) - LP/HP filters with LFO - Autopanner - Ambiance Generator - Haas Effect Processor (aka 'wavefront precedence effect') All features are demonstrated extensively in a ton of factory presets, and you can easily add your own user presets, which will automatically carry over across different host apps. All variables are exposed as AU Parameters in hosts which support automation. It also has a smart Random-feature, which may come up with usable results :-) Check out ruismaker.com for the user manual and audio demos.

- Granular synthesis engine
- Stereo spatializer with motion algorithms
- Multiple reverb algorithms
- Real-time control over grain speed and pitch
- AUv3 plugin compatibility
- Standalone app functionality

"In short, there’s oodles of scope here for sound designers and anyone who makes more experimental styles of music, whether EDM, chill or ambient." -SoundOnSound Unfiltered Audio's Silo is now available on iOS as a Standalone app or AUv3 plugin! Silo combines granular synthesis, audio spatialization, and reverb into a powerful, essential tool for sound designers and musicians everywhere. Silo combines microscopic granulation with macroscopic reverb tails to extract new realms from your existing sounds. Silo's first section, the granulator, breaks the incoming signal to tiny little bits (called "grains") before reconstructing it with massive amounts of control. You can change the speed and pitch of the signal independently and in real-time! These grains are then sent to Silo's unique spatializer, which throws the grains all over the stereo field. The spatializer contains a number of motion algorithms to add trajectory to your grains, such as the orbital "Moons", the shooting "Meteors", or the squirmy "Biological". After using this spatializer, you'll never want to use a traditional auto-panner ever again. Finally, the signal washes through one of Silo's many reverb algorithms, from small, resonant spaces to enormous, booming voids. From "Bokeh" to "Nebula", each mode can be tweaked to frame your sound perfectly. As an AUv3 plugin, Silo has been tested to work perfectly with Garageband, Drambo, AUM, Cubasis, Beatmaker, Nanostudio, apeMatrix, Loopy Pro, and more! Additionally, with its clear layout and smart resizing, Silo can be used on tablets and phones with ease.
