delay times of STK delays seem to be 1 sample off?
by volker böhm 03 Mar '08

03 Mar '08

hi, i was running some simple tests to hear the difference between allpass vs linear interpolating delay lines when i noticed that there is obviously a little bug in how the delay time is calculated in the delay UGens from STK. the following example feeds an impulse into a DelayA with high feedback and compares the tuning to a TriOsc. can't i trust my ears or is the tuning only correct if i add 1 to deltime before calculating the frequency for TriOsc? thanks, volker. Impulse imp => Gain out => dac; out => DelayA delay => out; TriOsc tri => dac; // test oscillator 44100.0 => float sr; // sampling rate // delay time in samples 150.5 => float deltime; deltime::samp => delay.delay; // calc tri freq from delay time // have to add 1 to deltime to get correct tuning sr / (deltime) => tri.freq; // set feedback level 0.999 => delay.gain; 0.3 => tri.gain; while(true) { 1 => imp.next; 6::second => now; }

Re: [chuck-users] is there a way to bundle mini audicle with different version of chuck?

According to http://audicle.cs.princeton.edu/mini/release/README.linux It would indeed be possible to compile miniAudicle with a different source for ChucK. quote: Tips ---- miniAudicle binds directly to the ChucK source code to provide an internal ChucK compiler and virtual machine. Thus, to compile the miniAudicle requires a copy of the ChucK source code distribution. miniAudicle includes the latest stable release of the ChucK source code in its own distribution, and provides a symlink to this ChucK source called 'chuck'. To bind to a different version of the ChucK source (version 1.2.0.5 or greater), unlink 'chuck' and recreate it, linking to the root directory of the desired source distribution (i. e., the directory enclosing src/, not src/ itself). >----Alkuperäinen viesti---- >Lähettäjä: vboehm(a)gmx.ch >Päivämäärä: 01.03.2008 19:08 >Vastaanottaja: "ChucK Users Mailing List"<chuck-users(a)lists.cs. princeton.edu> >Aihe: [chuck-users] is there a way to bundle mini audicle with different version of chuck? > >sorry if this has come up before, but a quick search didn't reveal >anything useful. >mini audicle comes with a pre built version of chuck. >right now i am playing around with chuck's source code and compiling >different versions. >is there an easy way to tell mini audicle what version of chuck to >use instead of the one which is included? > >thanks, >volker. > >_______________________________________________ >chuck-users mailing list >chuck-users(a)lists.cs.princeton.edu >https://lists.cs.princeton.edu/mailman/listinfo/chuck-users >

is there a way to bundle mini audicle with different version of chuck?
by volker böhm 01 Mar '08

sorry if this has come up before, but a quick search didn't reveal anything useful. mini audicle comes with a pre built version of chuck. right now i am playing around with chuck's source code and compiling different versions. is there an easy way to tell mini audicle what version of chuck to use instead of the one which is included? thanks, volker.

Scite script for Chuck
by AlgoMantra 26 Feb '08

26 Feb '08

Hi there - another question which will show you how little I know about linux (or any kind of) machines. I use Scite as my script editor on Ubuntu Gutsy (Linux/Debian), and I need a syntax highlighter for Chuck stuff. The wiki suggests that I use this python script as my IDE: http://wiki.cs.princeton.edu/index.php/Smallest_ChucK_IDE_Ever Now my question is...which directory do I put this .py script in to run? I mean, i've noticed that Chuck files can only be thrown in the VM from a terminal which is in that directory that contains the .ck file being chucked? And I often need to switch directories to access different files. Or can this .py run in some kind of global manner? -- ------- -.- 1/f ))) --. ------- ... http://www.algomantra.com

windows and under privileged users
by Jeremy Hunt 20 Feb '08

20 Feb '08

Hi All, I am trying to use ChucK to teach a digital audio synthesis class. The class is taught in a PC lab with winxp (I have little experience with winxp). My question, is it possible to run chuck --loop from under privileged accounts? My tests end up crashing chuck (same with miniAudicle) when I chuck + foo.ck to a looped chuck. What protocol does chuck use to communicate from one terminal to the next when using --loop? Any help on steps to get this running would be much appreciated. -jrmy

assignment of integers?
by Kassen 19 Feb '08

19 Feb '08

Fellow ChucKists, consider; ---------------------------- int foo @=> int bar; //yields semi-random high number <<<bar>>>; ----------------------- and; ----------------------- 1 => int foo @=> int bar; //yields "1" <<<bar>>>; 2 => foo; //yields "1" <<<bar>>>; ------------------------------ Integers seem to be in some sort of state of doubt between being assignable and not being assignable (maybe also in doubt about being a object? the poor things!). This becomes somewhat important if bar is a member of a class that -for it's member functions- would benefit from knowing what happens around it. I can still turn both foo and bar into length 1 arrays or keep passing foo as a argument to such functions but that's not as pretty. Yours, Kas. PS for those who hadn't seen this yet; length 1 arrays to trick integers into becoming full objects was cooked up by Frostburn here; http://electro-music.com/forum/viewtopic.php?t=23628 Maybe inspired by this strategy to turn functions into objects (in a roundabout way); http://electro-music.com/forum/viewtopic.php?t=23546 Tricky but useful.

chuck and jack fedora linux
by francis keyes 19 Feb '08

19 Feb '08

Hi All, When i first installed chuck a few months ago it worked right away without any problems. Now I have it installed on a new fedora Linux system and I can't get it to work. I want to use it with Jack so first I start Jack with qjackctl. Then I try to run the example foo.ck program and I get one of these two messages: JACK tmpdir identified as [/dev/shm] [chuck]: (via rtaudio): no devices found for compiled audio APIs! [chuck]: cannot initialize audio device (try using --silent/-s) Or sometimes just: JACK tmpdir identified as [/dev/shm] Aborted I've tried using it without Jack too with no success. Can anyone tel me how to troubleshoot this? Thanks!

Hi! I have been looking at Lisa a bit the last few days and cant really figure out how to load wave file samples into her. One way would be to chuck a SndBuf to her and let time pass, but it seems stupid because it is inefficiend in both code length, memmory useage and startup time. Is there any good way to load wave files to Lisas wave table? Regards, Johan Nilsson _________________________________________________________________ Mörkt och kallt?

Re: [chuck-users] ChucK + Summer Workshops
by Matthew Calhoun 12 Feb '08

I did one of CNMAT's Max/MSP workshops a few years ago; it was wonderful. The focus was more on learning Max and DSP/synthesis concepts than on composition. They don't seem to have any info up on 2008 workshops yet: http://cnmat.berkeley.edu/education/workshops.
