Watch out: this app can be very noisy, be careful with your ears and keep volume low initially!
Choose photos and images from your Photo Albums as the data source for noisy sound synthesis. Up to five touches on screen are detected, and the image r,g,b and intensity values at touch locations mapped to the parameters of chaotic and noisy sound synthesis algorithms. Three algorithms are provided:
1) Gravity Grid: a particle is trapped under the influence of gravity within a set of fixed bodies, and spins around chaotically at fast rates
2) Frequency Modulation: each touch controls one carrier and modulator pair using FM synthesis.
3) Nonlinear Synthesis: a special nonlinear differential equation with weirdly oscillatory solutions is continually solved.
If your definition of 'music' is limited to diatonic notes, you probably won't like this. But if you're up for some fun with noisy sound, you should enjoy the experience! Try different images as sources and remember to use up to five fingers at once to control each algorithm.
What's New in Version 1.2
Added a new synthesis mode based on square waves, alternative mappings for each preset, and a tube reverb simulation. Even noisier!
Just Needs Export Capability
You can get a wide variety of sounds using this app and unlike some of the other visual to sound apps, there is a tight link between the sound and the visual. The multi-touch playing adds a lot of variety too.
On some of the settings you can sometimes get clicking but in other modes there's a very tight integration between the sound and the visual.
It would be a fantastic and complete app if there was a way to export the sounds. Really could work well with other apps if it had audio copy.
It'd be nice if there were a way to record touches and play them back.
Hopefully Nick or some other developer will fill in the gaps to create an even more useful and creative instrument.
Incredible cryptic noise device!
If the subject line doesn't appeal to you, then stay away. If it does, then leap right into this. Continual discovery and some fun, harsh, noisy results. Thanks so much for creating this!
this thing is wonderful
if you're looking for a traditional instrument sound, you should look elsewhere. if you like noises and something that is easy to use, get this and spend hours deciding where to place your fingers.
