Simon Burton: SuperCollider and HyperSense

We use custom built USB sensor devices to control SC synthdefs over an ethernet connection. The demo would show one (or more) of these devices working and generating audio events in real time. (Pictures). For this demo we may need to host the USB devices on a Mac, but SC would be +running on a linux box.

Simon will be assisted by Alistair Riddell (ANU Centre for New+Media Arts).

Peter Chubb: Taming your old LPs

I have around 1000 LPs in various condition, having been collecting key recordings for 30 years or so. LPs are delicate, bulky, and inconvenient. So what to do?

In this talk I'll describe how I transfer audio from LP onto digital media, fixing the worst problems of the old LP on the way. I'll mention tools such as gramofile, gwc, lame, and cdrecord. I'll also discuss what to look for at the input end --- the turntable, tone arm and preamplifier; and ask for help with sound card technology.

Dave Robillard: Om, OSC, and the "LAD Philosophy"

Om is a modular synthesizer, built to address some limitations of currently available modular synths: subpatching, polyphony, multiple patches, realtime correctness, etc. A major design goal of Om was to avoid duplication of effort as much as possible, using standard LADSPA and DSSI plugins for all DSP and controlling the engine exclusively through the OSC (Open Sound Control) protocol.

The OSC controlled engine design means it can be used in many different configurations, with or without a UI:

Demos of Om used as a normal graphical modular synth, as well as some of these more interesting use cases will be performed.

The talk will focus on the advantages of this type of design strategy and interoperability between GNU/Linux audio applications, extending the modular ideas of Jack and the Alsa Sequencer into the realm of OSC. 2005
