Retro Future Inspired by the oil can delays of the 60s and our previous granular explorations, Curtis™ and Spunk™, Soup brings you a virtual magnetic fluid that you can record onto, slosh around, and play back from. You can use it as a unique delay effect or more like a granular synthesizer, concocting your own wholly novel sounds. Quantum Sound Soup breaks up recordings into individual sound quanta with which you can interact as if they made up an audio fluid. They can be played linearly or randomly, forward, backward, or even sideways. They can, moreover, be stirred together, giving a whole new meaning to mixing sound. Sounds Touching Not only is this an extremely visual audio experience, it’s terrifically tactile as well. With support for multi-touch, Soup lets you get in there and mangle the fluid in a way that’s simply not possible with knobs and faders. Audio Palette Soup will let you paint with sound. You can record external sounds through the microphone or import WAV files, slathering sound over the virtual fluid. Then your fingers can become play heads, reading back the sounds from any position, or multiple positions at once.
