Question regarding Sample level timing.
by Mike McGonagle 06 Feb '06

06 Feb '06

Hello all, I wrote this test this morning, and something seems amiss here with timing. Or am I understanding this wrong? /* The following code doesn't seem to work properly, as there appears to be a 2 sample delay from when the impulse is triggered from what is expected. as the 'doit' function is started at time 0.0, I would think that each and every impulse would be generated at 100::ms intervals, starting at 0.0, and not 2.0 The code generates the output below... */ impulse i => blackhole; fun void doit() { while(true) { 1.0 => i.next; 100::ms => now; } } now + 1::second => time later; spork ~ doit(); while(now < later) { i.last() => float val; if (val != 0.0) { <<< now, i.last() >>>; } 1::samp => now; } /* 2.000000 1.000000 4412.000000 1.000000 8822.000000 1.000000 13232.000000 1.000000 17642.000000 1.000000 22052.000000 1.000000 26462.000000 1.000000 30872.000000 1.000000 35282.000000 1.000000 39692.000000 1.000000 */ Thanks, Mike

Release schedule for 1.2.0.5

Hello Ge, Thanks for looking into the impulse bug so quickly. I was wondering if the development team has a regular schedule under which you are working? I was just curious at how often there will be updated releases for ChucK are being made. Thanks, Mike

redirecting console output
by eduard 28 Jan '06

28 Jan '06

Hello all, Is there a way to redirect the std output to a text file? I'd like to use chuck to annotate songs, i.e. when I hear a kick a press a midi keyboard and I tell chuck to output the elapsed time to the console. I'd like to write this output to a text file, but I haven't succeed. Could some one give me a hint? and if that hint is unix or c/c++ it'd be better. thanks in advance, Eduard

sndbuf questions, etc.

Hi all. Is there a way to make a table lookup oscillator with ChucK? I'm trying to load in soundfiles to be used as waveforms so that I can index them directly. I've worked through allocating an array and loading it with the samples of a file, but there doesn't seem to be a way that you can actually put them out to the dac again. Then I tried to do some other tests where I just read the file into an array outside of a function (since that seemed a bit more chuckian), then sporked a bunch of shreds, but it seems that when you change the position of the buffer from inside a function, it seems to affect the position in the other shreds. The last test I did, I had the file read in inside of the function and that seemed to work well, but quickly seemed to slow everything down. Any input is appreciated. Regards, Eric

Re: [chuck-users] winxp ChucK setup

My system path reads as: %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\ATI Technologies\ATI Control Panel;C:\Program Files\QuickTime\QTSystem\ This includes %\System32, so Chuck should be in the system path, I believe. My Chuck folder with bin, examples, and doc are all located in D:\Chuck. I use the start -> run -> cmd shell. When I enter "chuck --help" it loads all the chuck info, so I believe it's running fine. When I prompt to D:\Chuck\examples and enter "chuck otf_07.ck" or "chuck otf_07" though, it gives me "[otf_07(or.ck)]: no such file or directory." This happens when I attempt to load any file in this way. All the example files register in "Dir D:\Chuck\examples", so I'm stumped.

If I prompt to D:\Chuck\examples\, theoretically > I should be able to enter "chuck otf_01.ck" and have it launch, right? That's correct. What are steps you took to do this? - which shell are you using? via start->run... then 'cmd'? - what error message are you seeing? > I'm running Windows XP, and using the win32.exe ChucK (which I put in > System32). That's correct also. This should put chuck into your system path. After which you should be able to invoke chuck from any directory, using the command line interface. It may be that chuck.exe is still not in your PATH, it is inconceivable that c:\windows\system32\ is not in PATH, but still possible. Can you check which directories are in your path? You can do this right click on my computer (I think) and select properties, and under one of the tabs should be the default path - all the directories listed will be searched when invoking a program globally. Let's get this resolved! Let me know how things go. Ge! > I'm just trying out ChucK for the first time, and I'm not able to get > chuck to load a file.

A Bug? or is it a Feature?
by Mike McGonagle 24 Jan '06

24 Jan '06

Hello all, I was playing with some ChucK code that I wrote, and in copying some of the code to another file, I inadvertantly copied a global variable definition so that it was after a function that referenced that global variable. When I ran the code, I didn't get a message from ChucK that the variable was not defined when the code was compiled, and when the program ran, it would hang at the location where the global was referenced. (I don't have access at the moment to a running "ChucK", so I can only give an simple example.) fun void mySporkedFunction(float p1, float p2) { <<< p1, p2 >>>; globalVariable * 2 => float myLocalVariable; // do some sort of time function here } // define the global here 10.0 => float globalVariable; spork ~ mySporkedFunction(0.0, 1.0); When I ran my actual code, Chuck would hang up at the point where the globalVariable was referenced, in this example, that would be the second line off mySporkedFunction. The previous "print" statement would not output anything, until I hit Control-C to stop everything. Needless to say, I moved the global defintion to before the function, but I would think that there should be some sort of error message generated, or this should work as expected. Thanks, Mike

Question about Networking
by Mike McGonagle 23 Jan '06

23 Jan '06

I was working on some code in ChucK, and was thinking that it would be nice to be able to use an interface that I already have created using Pure Data. But, in order to do this, there would have to be something available that would be similar to either a MIDI event, or the like. Am I correct in understand that the "netin" and "netout" Unit Generators are specifically for transfering audio over the network? Are there any plans to create such an Event class? I would think something like this couldn't be written in ChucK, as there would need to be some sort of networking primitive to handle the connections and data transfer. How does Audicle connect up to ChucK? Is that purely through a commandline, with Audicle sending other commandline messages to a running "ChucK"? Thanks, Mike -- Help the Environment, Plant a Bush back in Texas!

about "dac/adc" to control input/out??
by Lewis Liu 23 Jan '06

23 Jan '06

Dear Sir, In my PC, there are two audio interface. One is the default in motehr board (SoundMax). Another is USB dungo. I can use --dacx and --adcx to force the audio input and ouput in SoundMax. But I can not use --dacx or --adcx to force the input in USB dungo. I do not know what is wrong. The codes are as follows: adc => gain g => blackhole; float x; while( true ) { g.last() => x; if( std.fabs(x) >= .05 ){ <<< x, "hello" >>>; } 1::samp => now; } Best Regards Lewis

I have re-posted the stereoChord EGG routine back up on the wiki. I now know that there is a system malfunction that prevents the text from showing: I thought it was my breath.

Is there any "Community" repositories yet?
by Mike McGonagle 20 Jan '06

20 Jan '06

Hello all, I spent this last weekend working on a piece using ChucK, and quite frankly, it was something that I had implemented using PD, but was never really able to get one part to work successfully (probably more due to a design flaw or something). But, I was very happy to say that, using ChucK, I not only got the basic parts to work, but I also got the part that I was having trouble with in PD. I am very impressed with ChucK. So, basically, I would like to start posting some of these things to get some feedback from others, as well as some critiques of both the programming as well as the resulting music/sound construction. Is there a part of the WIKI that can be accessed by regular users to post some things? Or should I just post something to the list here (as an attachment)? Thanks, Mike
