Hi guys Using ChucK on OS X, is there some easy way to re-direct its audio output to a file (for analysis)? Thanks, Arve

Running scripts sequentially
by Gonzalo 06 May '14

06 May '14

Hi, I'm trying to run multiple .ck files sequentially. Specifically I have a 'master' file that loads all the 'child' files via Machine.add. But then of course they run concurrently. For now I'm just advancing time in the master file before every Machine.add statement (ugly...). Is there a way to accomplish this nicely? Thanks! Gonzalo PS: This is my first message to this list. I'm working on a project with Chuck that raises *a lot* of questions, so I'll probably be coming back here often. :)

chuck vm options
by Al Matthews 29 Apr '14

29 Apr '14

Hello list. 1) Catching up a bit, it occurs to me that shell%> chuck --start `while(true) 1::second +=> now;` has been superseded by shell%> chuck --loop ; correct? Does ChucK any longer accept subprocesses or so, from the shell? 2) Also if anyone cares to distinguish or give an example for --callback Utilizes a callback for buffering (default). --blocking Utilizes blocking for buffering. then I'm much obliged as this is unfamiliar in some respects to me.

Re: [chuck-users] curious about chuck
by Perry R Cook 18 Apr '14

Oscillators of type (XXXOsc) do accept direct input from other UGs for Phase or Frequency. You just have to set the .op mode for those. In general, UGs don't accept sample-rate ChucK connection for arbitrary parameters, as very often one doesn't really want or need those to run at the sample rate. Control rate is arbitrary in ChucK, so to update the .freq of something non-Osc type, you would make a shred that does it at your sub-sample rate. You could even do it at the sample rate, of course. Here's an example: Flute f => dac; 880.0 => float freq => f.freq; spork ~myMod(); 1 => f.noteOn; 1*second => now; 660.0 => freq => f.freq; 1*second => now; 440.0 => freq => f.freq; 1*second => now; fun void myMod() { SinOsc s => blackhole; 6.0 => s.freq; while (true) { freq * (1.0 + 0.05*s.last()) => f.freq; 10 :: ms => now; // whatever rate you like here } } // Cheers!!!

curious about chuck -- very basic question
by Aaron Bohannon 17 Apr '14

17 Apr '14

After reading through the relevant parts of the language specification, I am unable to determine whether it is valid to use the chuck between a unit generator and a variable/property, like this: SinOsc s => dac; SinOsc lfo => s.freq; Obviously, anyone who's used hardware synths is going to want to do that sort of thing. I'm sure this has been discussed and debated a hundred times on this list before, so feel free to send me a link to someone else's answer. I just couldn't find any search terms that would pinpoint the issue. Thanks, Aaron

workshopping (atlanta)
by Al Matthews 04 Apr '14

Hello again. I am undertaking as of next month a series of livecode workshops in Atlanta, in which I expect to teach or demo a fair amount of ChucK. I'd very much appreciate hearing what your teaching | learning experiences in ChucK may have been. I've mined a lot of existing ChucK material, but I certainly appreciate examples as well. Naturally I will give full authorship credit insofar as I receive it, to any borrowed examples. Thank you. Al Matthews - http://fatmilktv.com Atlanta, GA, US +1 337 214 4688

Float assignment totally unexpected
by alfredo 26 Mar '14

Hello everybody! I'm running miniaudicle for ubuntu 13.10. everything compiles and even sound works. i'm just facing an unexpected behaviors with floats. <<< 12.2 >>> prints 12.000000 : (float) <<< 1.2 * 2.2 >>> prints 2.00000 : (float) 2.3 => float a; <<< a >>> prints 2.000000 : (float) i really want to solve this out as soon as possible. any advices? is a gcc/g++ issue? is chuck language issue?

Eternal chuckation
by Stuart McDonald 15 Mar '14

15 Mar '14

I'm trying to get a continuous ambient mix 'app', where once a SndBuf finishes playback, another will be instantiated. There should always be two SndBufs playing at all times. I can get this scenario working easily enough but the memory used by earlier playback isn't being freed up. It seems that as long as a parent shred (required to instantiate and monitor the sndbufs) is while-ing away eternally, the sndbuf remains in resident memory. This is a problem because as more sound files are selected and played the computer will eventually run out of memory. Switching to the command line I find I can chuck + simple sndbuf playing files and once playback is complete, memory use goes back to what it was. I already have a perl script running to take care of environment and execution of the program on boot, so I can modify that to periodically add new chucks. The problem now shifts to knowing when to identify that the current file has completed playback, and a new file should be added. OSC seems a good way of getting information from Chuck to the script. There's a Perl library for running an OSC server, so it seems like this could well work. But before I go down this slightly Rube Goldberg route, I wanted to check: is this really the Best Way(TM)? Thanks, Stuart

sending an array from ChucK via OSC
by dparson 09 Mar '14

09 Mar '14

Does ChucK support sending an array as such? I am already using a loop to create a OSC foprmat string "iif[BUNCH OF fS]", so I suppose I can just forget the "[]" in the format string and send a bunch of scalar floats instead of an array. the array size is fixed. But, I thought I'd ask. I can't find any docs to suggest it, and I don't have time to dig into the implementation. I need to get ready for this: https://www.facebook.com/events/194651817409105/ Thanks. Dale (Acoustic Interloper) http://faculty.kutztown.edu/parson
