I have a research project for which I need a variety of environmental audio streams, but for a number of reasons, I want to use purely synthesized sounds rather than just using pre-recorded tracks and sample-based simulation. I'm wondering if anybody in the ChucK community has any convincing environmental patches that they'd be willing to share. Almost any environments will do, so long as they're evocative of a place. Wind, rain, leaves in the trees, crickets chirping, waterfalls, waves on a beach - those are all fairly obvious examples of natural environments. I'm also interested in urban settings as well: traffic, stadium crowds, murmuring theater audiences, applause, industrial machinery... In addition to complete environments, good simulated sound effects that can be used as elements in an environment would also be useful: a car horn, closing door, breaking glass. I'm hoping that such synthetic effects will have parameters that can be adjusted to modify the character of the synthesized signal. For example, I have a "footsteps in the hallway" patch I've been playing with that can be adjusted to sound like footsteps in gravel or footsteps in grass, on sand, etc. (Mine isn't very good yet, so if you happen to have a good footsteps simulation, I'd love to compare yours with mine.) There are lots of environmental sounds that I haven't even mentioned, too, so if you have something you'd be willing to share, I'd love to hear from you. And maybe, if there's interest, I'll put together an archive of them to share with anyone else who's interested. Thanks -- Jeff Smith Computer Science Dept. University of Saskatchewan
