"Company "Amidio" has announced "Noise.io", the first official iPhone/iPod Touch sound synthesizer. It offers ESFM (Enhanced Subspace Frequency Modulation) synthesis that is capable of producing all kinds of noises and sound effects. Making iPhone sound is simple: user slides his fingers over the device surface, that produces sound that changes in realtime, delivering a unique sonic experience. The resulting sound can be synced to BPM via TapBPM function and can be even more enriched with sound effects like chorus, delay, flanger, etc. Noise.io comes with 81 presets and a user-friendly preset editor that allows creating user presets in no time. Noise.io will be available exclusively in AppStore on 08/25/2008, for $6.99.
The company has another 2 projects in the same field: Didjer.io (iPhone dijeridoo emulator) and Flute.io (iPhone flute emulator). There projects are in early alpha stage. Also the VST version of Noise.io will be released by the end of 2008."
