Granular Synthesis On Your iPhone, For 1 American Dollar

Curtis granular synth demo two from Lucas Kuzma on Vimeo.

This is a demo of Curtis (App Store link), a $1 granular synthesizer application for the iPhone.

Description:

Granular synthesis works by combining many tiny grains of sound from
an existing recording, generally creating new sounds with the textural
properties of the recording. Granular synthesis allows you to
regenerate the recording, playing it forward or backward at any speed,
to skip around the recording playing tiny slices of it at random, or to
loop a small portion with a varying loop size.

1] Touch the screen with two fingers and rotate a quarter circle to activate recording mode.

2] Use your phone’s microphone to record any sound. Try your voice, music from the radio, an instrument, your dog, anything!

3] Touch the screen with two fingers again to stop recording.

4] Touch or drag one finger anywhere on the screen to control grain
synthesis. The long axis of the phone controls your read position; use
this to select the portion of the recording you wish to read from. The
short axis of the phone controls the grain size; use this to sample
tiny slices or bigger chunks.

5] Double tap to disable or enable position slew. With slew enabled,
the read position slowly moves to where you tapped. With slew disabled,
you can jump directly to new positions in the recording.

SC3 on IDevise

Recently I was working on compiling SC3 for iphone. (I have an ipod touch 3g)

and finally I succeeded to install the SC application!!

I used xCode 3.2.4, and iphone SDK 4.1. I tried first the new version of xCode (4.0) but for me who is not really experienced with coding on xCode, it was like a hell. So I downgrade, and tried to followed the instruction.

You can download the source codes and xCode project for SC application via git. (http://supercollider.sourceforge.net/wiki/index.php/Developer_cheatsheet_for_git)

and I followed instruction from this post : http://new-supercollider-mailing-lists-forums-use-these.2681727.n2.nabble.com/Trying-to-build-SC-iPhone-td5883719.html#a5917860

There were several issues. Especially on frameworks/choosing the right version/getting familiar with the setup on xCode.

I don’t know how useful it will be. but now I can code a bit on train, and on bed without the laptop on my belly, and we’ll see what can come out.

well, yes I am also worried about my eyes too.
