5. Why Procedural?
• Samples take lots of time to make, adapt
and integrate
• Pre-recorded music gets repetitive, fixed
sound palette
• Audio takes lots of space (esp. for smart
phone games)
• Audio experience is not as interactive and
adaptive as the rest of the game experience

6. Inspiration
Live Coding - programming audio as performance art
shows some of the possibilities.
The BBC explains.
Digital music toys, such as Otomata

7. Supercollider
• Programming language and environment designed
for real time audio
• Started in 1996 by James McCartney, now an open
source project
• Smalltalk object structure, C style syntax,
functional properties (1st class functions, and
more)
• Download it from supercollider.sourceforge.net

language interfaces on the client side
