SampleToy is a new iPhone app that turns sound design into play.
The app is described as a "musical instrument/plaything". It's part sampler and part granular synthesiser.
You can use it to capture sounds through the microphone, then play, loop, pitch and distort them live on the screen.
There are also a variety of sound design features under the hood, such as resonant filters, delays and envelope. You can enable "stepped" mode to play your sounds like a traditional keyboard, or keep it in "free" mode for microtonal madness.
Once you've recorded a sound, use the main area of the screen to play it back at different pitches (up to 5 fingers at a time). You can crop the sound by dragging a selection over the waveform. The crop area is also multitouch and you can adjust the crop while playing the sound too.
Note: Sampletoy requires audio input, so works only with the iPhone (built-in mic or headset mic) and iPod Touch 2G (headset mic).

Sampletoy is available now for US $1.99 in the App Store.
