Day of the Triffords from Andrew Sorensen on Vimeo.
I've been messing around with various methods for presenting FFT information recently and this screencast is based on some of these ideas. This particular screencast uses impromptu's analysis audiounit to retrieve fft data which is then loaded into an image. The image is then blurred using a gaussian filter. The image data is then pulled from the image and converted for use in vertex and colour arrays in OpenGL such that rgba is xyzw and rbga. The result is surprisingly organic
Transmissions in Sound from Andrew Sorensen on Vimeo.
A video recording (camera audio quality) of a live coding performance at the Transmissions in Sound night at ANU in Canberra (Sept 2008). This ended up being a pretty mellow performance - a little to mellow - but them's the breaks.

This section contains real-time performances by Andrew Sorensen. All audio and visuals (including the programming code) are recorded direct to disk using Impromptu's start-movie-capture command. They are presented without any post editing, processing or modification (aside from compression). If you don't have quicktime you should be able to play back using VLC
UMDT
An eclectic mix of sampling goodness for your listening pleasure. Including spoken dialogue (spoken by yours truly) from Under Milkwood (Dylan Thomas), traditional chinese sounds and a mix of western jazz and orchestral sources.

An Orchestral Study
Largely as a technical exercise I set myself the task of live-coding for full orchestra. This is proving to be quite a challenge!! The musical result is a little weak but as a compositional exercise I think it's interesting.

A Study in Pärt
A study in simplicity - a study in Pärt.
Because sometimes less is more!

Just For Fun
No craft or finesse here! Noise, nurbs and general madness abound. That classic love tale - OpenGL meets Sound Synthesis. What can I say, it was all just for fun :)

Antiphony
"Antiphony" explores the development of an antiphonal sound mass with four trumpets and four trombones playing in surround. The work uses Apple's Head Related Transfer Function (HRTF) implementation to provide a pseudo surround experience and is best experienced using headphones.

Stained
"Stained" is a combined audio and visual live coding performance. Along with the programming code itself, the work's primary visual content is a photograph, taken by the author, of a stained glass panel in Bath Abbey Somerset UK. A brass choir is used to present an increasingly aggressive chant reflecting and effecting the stained image.

Strange Places
"Strange Places" doesn't really know what it wants to be - a grungy noise piece or 70's electro pop whale song? In the end neither of either! An improvisation by Andrew Sorensen. Untuned sounds from NI's Battery all other sounds from Urs's ZebraII.

A Study In Keith
"A Study In Keith" is a work for solo piano (NI's Akoustik Piano) by Andrew Sorensen inspired by Keith Jarrett's Sun Bear concerts. Note that there is no sound for the first 2 minutes of the performance while initial structures are built.
Not quite Keith, but inspired by Keith :)
Enjoy!
