Simulating environmental audio
by Jeff Smith 22 May '08

22 May '08

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

I like alias-noise and 8bit
by Atte André Jensen 22 May '08

22 May '08

Hi I'd like to resample a 44100 signal to something like 10K *and* hear the alias noise. Also I'd like to resample to lower bitdepth, something like 8 or 6 bit. 1) How it that most efficiently done with chuck? 2) I event thought it might be possible for me to implement this as a real UGen. My plan would be to start from one of the simple UGens (gain), and expand/modify from there, but before even looking into the chuck source, is there any documentation about doing this? Should I expect this to be more effective in implenenting in chuck-code, and if so about how much? Also. supposed I actually succed in making something that works, could it be included in future chuck-releases? -- peace, love & harmony Atte http://atte.dk | http://myspace.com/attejensen http://anagrammer.dk | http://modlys.dk

ChucK linux requirements issue
by Kassen 22 May '08

22 May '08

Dear list (and devs/ admins), The ChucK download page ( http://chuck.cs.princeton.edu/release/ ) doesn't mention that on Linux ChucK requires a 32 bit system (and not 64, right now). I strongly suspect this to be the cause of confusion/segfaulting here; http://electro-music.com/forum/viewtopic.php?t=26414 (though I may be wrong) I would recommend putting this "on the packaging" so we can go on to new and innovative ways of seg-faulting and being confused. In case I'm wrong; do we have a Fedora-expert who might be able to help Flies there? Yours, Kas.

more minor Mini stuff (Linux)

When [ctrl]+[n]-ing¹ up a new file under Linux (windows is fine) the cursor isn't placed in the new file's window. In the interest of speedy keyboard-based workflow I'd like it to be. Yours, Kas. ¹ok, that's probably the limit to what can be verbed...

hello Ive been working on triggering Osc by the use of the keyboard and im still a having trouble I read the kb.ck file in the hid folder to figure out how it triggered and output the keys so i came up with the below syntax. // setting up the keyboard to trigger Osc // this should trigger a middle c tone when A key is pressed { if (msg.is ButtonDown()) and if (msg.my_keynumber = 65 then SinOsc s => Dac; 261 => s.freq; 1::second => now } it still giving me errors ? even when i running the kb.ck file in chuck any help would be great thanks Gabriel --------------------------------- Be a better pen pal.

Mini font resize bug (minor issue)
by Kassen 18 May '08

18 May '08

Dear fellow ChucKists (particularly Spencer), Some time ago I set the font of the Mini (latest version, ALSA, Linux, in this case) to have a huge size so I could easily demo something to a friend of mine. Now, I had to set it back and while the font got smaller immediately the cursor was still at the old (huge) height and so was the space between the lines. Re-starting the Mini fixed this issue. I'm not sure what the current best place to archive such bugs in the Mini is so sending it here. Yours, Kas.
