good until loop
by Timothy Leonido 28 Sep '10

28 Sep '10

Would anyone mind sending a good example for loop "until" ? I simply want a shred to stop automatically after a 10 seconds. Here is what I wrote: do{ Std.rand2f(200,50.0) + Math.sin(v*100.0)*20.0 => v2 => f.pfreq; Std.rand2f(5000.0, 60) + Math.sin(v*30.0)*80.0 => f3.pfreq; Std.rand2f(1500, 80.0) + Math.sin(v*200.0)*50.0 => f2.pfreq; std.rand2f(.551,.549)=>buf.rate; .0+(.9*maybe)=>buf.gain; 0=>buf.pos; .1:: T =>now; } until (5::second); thanks so much! -tim

random seed

if we use a random seed, f.e. Std.srand(120); will this affect all the random function inside the sketch? and if so, how can we turn it off? thanks

How to get better-sounding instruments?
by Tambet 11 Sep '10

11 Sep '10

Got such question: there is a set of instruments included from STK, also there are some reverbs etc., but I cant make them together do very natural sounds; I also don't want to use wav as I can't cange it's params. I do not have natural instruments to play in nor will to do so. Questions are: - Are there some good ways to connect ChucK with additional synthesizers in such way that I could get sample-by-sample output and slow down the generation of wav (with -s flag). - Are there more synthesizers built-in to ChucK. - Are there add-on modules with more instruments. - Are there examples about how to build natural sounds with those built-in oscillators and effects. As I try to get something, what would not sound too electronic or too flat. Tambet

operators
by Lars Ullrich 09 Sep '10

09 Sep '10

Dear list, Is there a way to do this operator functions in chuck? ">>" Shift all bits to the right ( has the effect of dividing a number by a power of two, but is less expensive in computer time.) "&" Bitwise intersection of two numbers. The & object performs a bit- by-bit "and" of two numbers (expressed in binary for the task). It is similar to the operator found in the C programming language. Any help will be much aprecciated!

Chuck garbage collection needs a manual
by Tambet 07 Sep '10

07 Sep '10

Hi again! As Chuck lacks garbage collection, it's probably The language, which needs a manual about garbage collection - I mean, a manual about lack of it. Googling "chuck programming garbage collection" gives these pages: - The Ultimate Top 25 Chuck Norris “The Programmer” Jokes - Chuck Esterbrook: Geek of the Week - Java Programming - Hump Day OT It would be good to know, how much memory things take, how to keep memory from growing full etc. For example - if I close something, will it release memory?

Writing wav results in empty file
by Tambet 07 Sep '10

07 Sep '10

Writing wav will result in file with correct length, but silence. BTW. how to make it so that if it is too slow to play it realtime, wav is still correct with no noises? Could you give exact command line for that? I'm using debian lenny with xfce and alsa+oss. Chuck is compiled for alsa support (I might want to change it already). Tambet

ChucK is too short.
by Tambet 06 Sep '10

06 Sep '10

The name "ChucK" needs some kind of prefix or suffix to give some method of good Google searches. "ChucK music" gives ChucK berry; just "ChucK" gives a movie; "ChucK videos" is useless. If Google did understand the last capital letter, it would be all fine. Google's own language is Go (or "Google Go"). They have another way to write it - "Go-lang". Go-lang gives all necessary things. "Go programming" does the same, but for general searches, this is not good - you might search for Go examples (and this sight might have no hint about programming) or Go users. You could search for Go libraries (not "Go programming libraries") or e-mail applications written in Go (no "e-mail applications written by programming in Go"). Just having some convention - for example that "ChucK" is abbreviation of "Chuck K..." and then having this "Chuck K..." in title or first occurrence of language's name in each good page talking about ChucK. Otherwise it's just too much work to search :) So ..ChucK name conquest? With this <http://www.dasher.org.uk/> powerful application I found a few days ago it took half of minute to find my own suggestion - "Chuck Kit". It could be also "Chuck sound Kit" or "Chuck soundKit" (to keep the case convention). I would be happy if it was *anything* - anything except some very common english name, which gives us all kinds of stars and TV programs when googled for. Tambet

Re: [chuck-users] ChucK is too short (Tambet)

As with much Google, just adding the right word(s) helps a lot. Yes, ChucK alone brings up Chuck Norris (and why wouldn't it?), but adding "Language" or "Unit Generators" or "Live Coding" usually gets the list you want. PRC > 5. ChucK is too short.
