time goes backwards (and I don't like that)
by Robert Poor 15 Mar '09

15 Mar '09

I can make time go backwards. Here's the file: ========================= Event _e; time _t; spork ~ beatProcess(); while (true) { now + 1.00001::second => _t; _e => now; <<< "returned from _e => now at", now >>>; } fun void beatProcess() { while (true) { _t => now; <<< "broadcasting at", now >>>; _e.broadcast(); me.yield(); } } ========================= And here's the output: ========================= bash-3.2$ chuck foo.ck broadcasting at 44100.441000 returned from _e => now at 44100.000000 broadcasting at 88200.441000 returned from _e => now at 88200.000000 broadcasting at 132300.441000 returned from _e => now at 132300.000000 ========================= The "while(true)" shred sets _t to the time at which it wants to be woken up. Note that (intentionally) the increment is slightly over a second. It then blocks on event _e. Meanwhile, the beatProcess() shred blocks until the time in _t, then triggers event _e to resume execution of the while(true) shred. What happens: - the beatProcess shred triggers _e at time 44100.441000 - the while() shred returns from its wait at time 44100.0000 One might think that the while(true) shred woke up *before* _e got triggered, but Apple isn't yet building computers with tachyon technology. Can someone tell me what's really going on??? Failing that, know any doctors who will prescribe a selective serotonin reuptake inhibitor to keep me from tearing my hair out? Thanks. - Rob

problem with osc over network
by Bozelos Dimitris 14 Mar '09

14 Mar '09

Hi all, I'm working on a group project and I chose to use chuck not having "chucked" at all before. So we need to send / receive osc messages over the network with the other groups members and i've run into some problems, I don't receive the messages other people send me. I can send messages with chuck succesfully and receive successfully with supercollider. So there is no problem with the network / firewall. Here is my code for receiving: OscRecv recv; 6449 => recv.port; recv.listen(); recv.event( "/address, f" ) @=> OscEvent @ oeFloat; float k; while( true ) { oeFloat => now; while( oeFloat.nextMsg() ) { oeFloat.getFloat() => k; <<<k>>>; } 1000::ms => now; } Is there anything that I miss? This code works fine at localhost (from a chuck shred to another). The other people are sending messages with Max/MSP and SuperCollider, can this cause problems? Can there be a mismatch of the type of the incoming message with what is expected? Although I was sure while testing that the message from Max/MSP was sent as a float, can this be a problem somehow? Any thoughts would be appreciated, Dimitris ___________________________________________________________ Χρησιμοποιείτε Yahoo!; Βαρεθήκατε τα ενοχλητικά μηνύματα (spam); Το Yahoo!

cross-referenced classes?
by Robert Poor 13 Mar '09

13 Mar '09

Assume I have the following: ===== file: scratch.ck ===== public class Scratch { Sniff _sniff; } ===== EOF ===== ===== file: sniff.ck ===== public class Sniff { Scratch @ _scratch; } ===== EOF ===== How does one compile cross-referenced classes? Neither "chuck scratch.ck sniff.ck" nor "chuck sniff.ck scratch.ck" bring joy. (There's a similar question for any class that has a reference to itself as a member, such as a linked list. But I'll save that question for the next time I need to flaunt my ignorance.) - Rob

Bad return signature in pre-constructor leads to null instance
by Robert Poor 12 Mar '09

12 Mar '09

Got a bug for the team. Don't ask me how long it took me to track it down. Consider this code and the effect of running it: ============== public class Foo { bad_pre_constructor(); fun float bad_pre_constructor() { <<< "bad_pre_constructor, this =", this >>>; } } Foo bad_foo; <<< bad_foo =", bad_foo>>> ============== % chuck foo.ck bad_pre_constructor, this = 0x634720 bad_foo = 0x0 ============== Note that the instance of bad_foo is null. Now consider this code: ============== public class Foo { good_pre_constructor(); fun void good_pre_constructor() { <<< "good_pre_constructor, this =", this >>>; } } Foo good_foo; <<< good_foo =", good_foo>>> ============== % chuck foo.ck good_pre_constructor, this = 0x634720 good_foo = 0x634720 ============== Note that the instance of good_foo is a reasonable non-null value. Did you spot the difference? "bad_pre_constructor" is declared (improperly) to return a float, but it doesn't, and an instantiation of Foo silently returns a null. "good_pre_constructor" is properly declared with a void return, and an instantiation of Foo returns a good value. So yes, this was operator error -- it's an error not to return a value when you claim you're going to. But ChucK fails silently, at least until you get hit with a NullPointerException some time later in the execution. This is not friendly behavior. - Rob P.S.: Uh, is this the right forum for reporting bugs like this?

benchmarking UGens
by Atte André Jensen 12 Mar '09

12 Mar '09

Hi We all know that chuck is not the fastest audio software out there. But I guess like me you've all found ways to work around that. I often found myself wondering "how much can I save by disconnecting this UGen" or "exactly how expensive is another NRev". For this purpose I started to do some benchmarking in the form of a bunch of .ck files and a bash script. My initial results are here: http://atte.dk/chuck/results.txt The first line is "chuck --loop", so the wm alone. "nb" is the number of files, "cpu" is the cpu usage as reported by htop on my laptop (2Ghz Intel dualcore), and "cpu normalized" is cpu-usage (simple multiplication) at nb=100. Of course this doesn't make sense without seeing the .ck files, so I've put them here: http://atte.dk/chuck/performance_tests.tgz I'm quite aware of that this approach is very un-scientific, so any input on how to improve it is more than welcome. Esp. I'm wondering how 10 * PRCRev = 7% and 50 * PRCRev = 46% (should have been 35%). I'm gonna continue my tests, but you're all welcome to supply files for testing. Maybe this should all end up on the wiki? NB: This is in no way a critique of the developers. Sure I would love to see a faster chuck, but we still love it and use it. -- Atte http://atte.dk http://modlys.dk

negative zero
by Robert Poor 01 Mar '09

01 Mar '09

I'm troubled by ChucK's handling of negative zero. A variable set to -0.0 is indistinguishable from a variable set to 0.0, except in printing. This is not a problem in everyday practice, but it seems likely that it will cause trouble when you pass to an external program. [Why would you set a variable to -0.0 in the first place? Try this: (-3.0 % 1.0) => float bar;] Comments? ==================== 0.0 => float foo; -0.0 => float bar; // even though foo and bar print differently... <<< "foo = ", foo, " bar = ", bar >>>; // in ChucK's eyes, they are both considered to be zero... <<< "sgn(foo) = ", Std.sgn(foo), " sgn(bar) = ", Std.sgn(bar) >>>; // and they are equal... if (foo == bar) { <<< "equal" >>>; } ==================== produces ==================== % chuck test.ck foo = 0.000000 bar = -0.000000 sgn(foo) = 0.000000 sgn(bar) = 0.000000 "equal" : (string) ====================

converting from dur to float
by Robert Poor 28 Feb '09

28 Feb '09

Is there truly no way to cast from a dur to a float? I'm writing a sketch of a TapTempo object. It measures the duration between events to estimate a tempo (in my case, expressed in Hz), which of necessity means *somewhere* I need to convert from a dur to a float. But I haven't figured out how to do that. Suggestions? - r

small note on LiSa.feedback()

26 Feb '09

Dear Dan, readme_LiSa2.ck lists; // mylisa.feedback(float); set feedback amount [0,1] for recording As far as I can tell it takes numbers larger than this as well as negative ones; -------8<-------------- LiSa l => dac; -5.0 => l.feedback; <<<l.feedback()>>>; -------------8<-------------- Amounts with a magnitude of over 1 may be unpractical/dangerous but since we will potentially be dealing with a especially perverted (and interesting!) form of Karplus Strong here I feel the option to use negative number here is rather relevant.

Re: [chuck-users] Introducing the KNoW Wave Generator
by Les Hall 24 Feb '09

24 Feb '09

Sounds very interesting, especially the beginning. After a while my own pattern recognition kicks in and it becomes a bit predictable. I wonder if you could use your boolean walker to generate more dynamics in the storyline, to make it more expressive, or to have more distinction between rhythmic parts and freeform. I must say I never heard of No Wave before, so perhaps this makes no sense in this genre. Arthur Hi Arthur, Yes, its all in how you code the logic matrix of the boolean sequencer. What I'm doing is drawing a diagonal line in the matrix with a decreasing probability of ones as you move away from the line. It looks like this: 0 0 0 0 1 1 1 1 0 1 0 1 1 1 1 1 1 1 1 0 0 1 1 1 1 1 0 1 0 0 1 1 0 1 1 0 1 0 0 0 1 0 1 1 1 1 0 1 1 0 1 0 1 1 1 1 0 1 1 0 0 0 0 1 0 1 1 1 0 1 0 0 0 0 1 1 1 1 0 0 0 1 0 0 1 1 1 0 1 0 1 0 0 1 0 0 0 1 0 1 1 0 0 1 0 0 1 1 0 1 1 1 1 0 0 1 1 0 0 0 1 1 1 0 0 1 0 0 0 0 1 0 1 1 0 0 1 1 1 1 0 0 1 0 If you stare at that matrix a little while you'll see the diagonal line from lower left to upper right of greater ones density, plus plenty of random bits strewn about. I suppose that much randomness is what makes it seem predictable. It's predictably unpredictable. But I can write code that makes other kinds of boolean sequencer logic matrices. In the past, in my soft synthesizer that has one of these as an array of MAUI buttons, I have had good results drawing circles, lines, and triangles. I was able to make some good rock guitar riffs that way. Actually the randomness is intentional for No Wave, which is supposed to be composed of a mix of wandering notes and hard driving rhythms. But for something else you wouldn't want so many bits strewn about in the logic matrix. So yes, coding the matrix in different ways will give completely different results. Les (Inventor)

by Ge Wang 21 Feb '09

21 Feb '09

Dear all, Perry and I will be teaching a 1-week intensive summer course on Sound Synthesis and Digital Signal Processing in ChucK, to take place from July 6th - July 10th, at CCRMA, Stanford University. The course fee is $650 and includes the course textbook "Real Sound Synthesis for Interactive Applications" by Perry (see below for more information). Should be fun! We sincerely hope you can join us! All the best, Perry and Ge! --- Here is more information: http://ccrma.stanford.edu/workshops/2009/ July 6-10 Sound Synthesis and Digital Signal Processing in ChucK Perry Cook, Ge Wang Description: This 1-week course will introduce basic concepts in sound synthesis, digital signal processing, and programming in the ChucK language. This workshop is intended for: If you know programming (C, Java, C++ Objective C, etc.) then you'll know ChucK thoroughly by the end of this course. If you don't, then you'll know some programming and some ChucK. If you have math background, then you'll know quite a lot of DSP by the end of this course. If not, then you'll have an intuitive grip on many of the concepts. If you know DSP but not physical modeling or other sound synthesis techniques, then you'll know those by the end of the course. Workshop structure: Morning lectures will cover time and frequency domains, additive, subtractive, FM, and physical modeling synthesis, and basics of ChucK programming. Afternoon labs will reinforce course topics through hands-on exercises and individual work based on participant interests. Text: Real Sound Synthesis for Interactive Applications (included in course fee).

idiom for requiring a class file?
by Robert Poor 18 Feb '09

18 Feb '09

More questions: What's the proper ChucK idiom for automagically loading a class file from a file that uses that class? I can manually add MyClass.ck to the VM before loading the calling file, but that doesn't seem particularly scalable. Is there an idiom that is equivalent to "include" or "require" in other languages? - Rob

recording audio input under ChucK control
by Robert Poor 18 Feb '09

18 Feb '09

fellow chukka's: I have not yet found an obvious way to record audio input under ChucK control. The SndBuf.write() method is documented as "not yet implemented", and test code appears to confirm that it isn't implemented. I want to use ChucK to record snippets during a live performance using MIDI input to control when the recording starts, then use ChucK to play back processed snippets. I *really* don't want to be switching apps (more specifically -- I don't want to be fiddling on a Mac keyboard), so I need Chuck to control it all. So my gambit -- yet to be tested -- is to use ChucK to spawn a command line function to do the recording, such as: def void recordSnippet(string toFilename) { system ("sndrecord " + toFilename); } ... where sndrecord is a command-line recorder (such as /Developer/ Examples/CoreAudio/Services/AudioFileTools/afrecord). Questions, always questions: - Given my constrains (real-time recording must be controlled from a MIDI device, not from a Mac keyboard) is this a sensible approach? How have other people managed this? - in the ChucK system() call, is there a way to attach to stdin / stdout of a spawned process? In this particular case, I would like to send it a string to stdin of the spawned process to tell it when to stop recording. - Aside from the afrecord utility in Mac OS /Developer, are there other command-line recording apps that people use and like? Thanks. - Rob

dur frame?
by Kassen 18 Feb '09

18 Feb '09

Fellow ChucKists, suppose we have a stream of data coming in over HID (or MIDI or whatever). Suppose we wish to have something done based on the data that came in over the last frame and we want to make sure this gets done before the next frame starts and hence before any new data could come in. This would be useful to create smooth transitions based on HID data at the expense of lagging one frame. How would we go about this? I don't think we can without introducing "magic numbers" based on our settings. I'd like to propose the introduction of a duration named "frame" of a length of a "n::samp" where n is the size of a single frame in samples. Yours, Kas.

Timing with ChucK
by rkramer 18 Feb '09

18 Feb '09

Being a relative non-programmer, I'm not quite sure if this is even possible... My goal is a quick and dirty program that will measure the time between two large audio events (in the input sound buffer, live recording.) Essentially what I want to do is use ChucK for practical demonstrations of simple physics... IE demonstrating average velocity of a falling object (that generates a sufficiently loud event when it is released and when it hits the floor.) Any tips where to start on this project? Ryan

ChubbY (ChucK in Ruby)?
by Robert Poor 14 Feb '09

14 Feb '09

Has anyone considered of implementing all the wonderful functionality of ChucK in Ruby? I'm not trying to start a fight or ruffle feathers -- it's an honest question. I love ChucK for all of its functionality -- it has a full house of great unit generators and signal processing objects coupled with an easy-to-use thread / scheduling mechanism. But for all that, I find ChucK the language lacking. For example, when I really push on defining classes, I can't do all the things I'm used to. Might not a marriage of ChucK's rich functionality with Ruby's rich language be nearly ideal? At the very least, we'd get Mr. Bowkett to -- in Yoda's words -- TFSU. - Rob

Re: [chuck-users] determining the type of an Object in code
by mike clemow 12 Feb '09

12 Feb '09

Hello, fellow Chuckers! I keep finding myself returning to this issue of trying to determine the class of an object instance at runtime. We talked about it here: https://lists.cs.princeton.edu/pipermail/chuck-users/2008-September/003242.… I recently pulled from CVS and started fooling around and discovered a remarkably simple hack. There's a method in Object, toString(), which returns a string containing the class of the object as well as the reference ID. Like this (supposing a class called "Test"): "Test:11ceff0" There's also a stub in chuck_lang.cpp for a method getType(), which isn't implemented (yet). So, I copied the implementation of toString(), minus the printing of the reference ID, and placed it where the implementation of getType() should be. Now all objects (not UGens yet, although that would be sweet) respond to getType(). Example: class Test { 5 => int i; fun void sayHi() { <<< "hi" >>>; } } Test test; test @=> Object o; // Object still knows it's a Test! <<< o.toString() >>>; <<< o.getType() >>>; // Object can't sayHi() //o.sayHi(); // but this is now possible if( o.getType() == "Test" ) { (o $ Test).sayHi(); } The above code will print this: "Test:11cf160" : (string) "Test" : (string) "hi" : (string) This makes me very happy and opens up many doors, although I have no idea what getType() was originally intended to do--I assume a similar purpose. I'm sure that this will work as a mod to the current release as well, although I made my changes in the CVS version (I'm excited for FileIO). This ought to make implementing things like ArrayList a lot easier. ;-) I consider this a feature request (for this or something like it). I think this would be super helpful for UGens and primitives also. Primitives, however, don't support the dot notation... Oh well. I'll take what I can get. -Mike -- http://michaelclemow.com http://semiotech.org

cheap parallel ChucKing
by Graham Percival 11 Feb '09

11 Feb '09

Hi all, We're using ChucK as a cheap synthesizer for a bunch of new electronic instruments. To make best use of the dual-core CPU, we're launching ChucK in two separate threads: $ chuck first-server.ck & $ chuck second-server.ck This works great (it almost maxes out both cores on a mac mini), although the second instance of chuck complains that it can't bind to port 8888. Are there any potential pitfalls to this method? I know that we can't (easily[1]) get any communication between these two chuck instances, but in this case we don't need it -- each instrument's synthesis is completely independant of the other one. In CS terms, this problem is "embarrasingly parallel". :) [1] we could add code to our OSC servers to send messages back and forth via loopback, which isn't precisely "hard", but it's not as easy as everything else we do in ChucK -- this language is awesome. :) Cheers, - Graham Percival

How can a non-programmer start to make use of Chuck?
by Mark Knecht 09 Feb '09

09 Feb '09

Hi all, I've been thinking for a while that I'd like to try out a tool like Chuck. I'm on an AMD64 Gentoo platform it seems that Chuck is my best bet. I've started scanning the chuck-users list to get familiar with what sort of discussions happen here - and they are interesting - but as I am more of musician than a programmer I'm wondering how I might attempt to get to know Chuck better? To start exploring I've built Chuck-1.2.1.2 from portage and am building miniaudicle now. Neither has yet made a sound. I *think* (but am not sure) that I'd like my first exploration to be in the area of using Chuck to create rythmic patterns of sort of a break-beat nature using noise generators and filters as the sound source. This is not something I'm set up to do with any of my other tools in Linux or Windows so if I was successful it would add another tool to my tool box. I'm wondering whether more experienced folks: 1) Think this is a reasonable goal? and 2) Might have suggestions about how I'd get started? Thanks in advance for any comments and ideas. Cheers, Mark
