Fracture – An Audio Unit

I have an occasional interest in digital audio programming, and followed up an idea I had on the train the other day for an audio effect. I’d not written a plugin for a while but Xcode has a nice template project for an Audio Unit plugin and Apple has a good tutorial on the web so it didn’t take long to try out my idea.

Introducing Fracture

Fracture breaks the incoming sound into granules and then delays each granule relative to its volume. As you can imagine this sounds like quite a mess, the sound fractures in time and place like a skype call going through three separate satellites.

There are controls for wet/dry mix, granule size, the ratio of how volume effects the delay and the ability to add a fixed delay to the dry signal to help things line up. I’m not sure if there are many useful settings in there but it does create a wide variety of effects depending on the source material.

Its a little raw but please give it a go.

To use this audio unit, download the zip file at this link. Unzip it and place the component file in your home folder under Library/Audio/Plug-Ins/Components

It works under Garageband or any Mac audio software that supports Audio Unit plugins.

H.FBK

h.fbk is an original digital instrument I made. It attempts to recreate the sounds of harmonic feedback with some custom distortion to give a rich sound.

It has 15 touch triggers and responds to multi touch positions and movement. If you hold your fingers `just so` and then move them `just so`, you can get that nice, fading out, guitar feedback where it drifts to different frequencies. Well at least thats what I’m aiming for.

Free on iTunes – try it

1 2 3 Sheep!

This is the first app-titude educational iPod app. This is a whole range of apps we’re developing for use in schools, with an online system for teachers to track students progress.

There’s a lot of love gone into this app, featuring graphics and animation by Julian Frost and programming and music by me!

There are three activities, and a lot of thought and attention has gone into feedback, progress and adaptive difficulty. So far kids seem to love it and respond really well to it.

I’m really proud of this game and looking forward to seeing more of the app-titude series take shape.

iTunes Link – its not free, but its worth it
