[this is the looch!]
iLooch is an
application designed to generate evolving ambient sounds.
The music is not "sampled"; it is instead created by generative
rule-sets coupled with various synthesis techniques.
They'll go on forever and ever! (well, at least for
a few hours...) Because the music is being
constructed on-the-fly, each time it plays it will be slightly
different. Such is life.
I used a synthesis and signal-processing code library
to realize the audio (yes, Apple, it is compiled
entirely using XCode Tools), including many physical-model
algorithms to produce the snazzy sounds. For those interested
in such things, the iPhone/RTcmix code is
It was like the proverbial Trip Down Memory Lane to code
this app using the Interface Builder and Objective-C,
as I did the first "Looching" to
learn the [then new] NeXT MusicKit many years
ago (see below for a link to the
history and various looching programs).
Although all of the iLooch musical algorithms were
built for this app, I did base a few of them on code from
previous looching programs, listed in that link below.
[note: iLooch will also run on an iPad, but I have a more
extensive version under development for the iPad.]

Why am I charging $0.99 for iLooch? --
This is the first program I've written and distributed for which I am
charging money. Mainly this is an experiment, or at least that's what
I tell myself in a misguided attempt to retain a sense of communitarian
virtue. I'm basically a public-domain kinda guy, but I read
some silly article somewhere saying that if I charge a nominal fee
people will take the app seriously! And iLooch is
one serious app. Seriously. I'm actually hoping to recoup
the annoying $100.00 I had to send to Apple to join the iPhone Developers
Program. If I wind up making BILLIONS more, I'll probably donate a bunch

Here are a few examples of output from the iLooch app:
How does it go?
- the blue squares -- select or turn on/off different
looch-musics. The blue-colors shift,
watch the virtual grass grow... isn't that fun?
- the volume slider -- relative volume (overall iPhone/iPod
volume set by the hardware controls)
- the info button -- this will get you to the 'back' screen:
- the "done" button -- touch this to get back to the 'front' screen
- the looch -- this is, in fact, a picture of Loocher howling.
- the web page info button -- touch this and it gets you here to
this very page you are reading now!

There are other apps to be had, too.

I hope you enjoy this stuff!
