Error in Console
by Daniel Cooper 13 Aug '20

13 Aug '20

Hi everyone, This might seem like a very basic question, though I’m getting an error in the Console that makes it impossible for me to use MiniAudicle: “[chuck]: (DirectSound) error (Generic error) creating input buffer (Default Device)! [chuck]:(2:SYSTEM): | | | cannot initialize audio device (use --silent/-s for non-realtime)” I’ve tried everything I could find online, and it seems my audio drivers are working. The program worked just fine on my old computer, but I have no idea how to get around this on my new computer. Has anyone come across this before? I’m using version 1.4.0.1, Windows 10. Any help would be greatly appreciated! Cheers, Daniel

chuck.exe is infected!
by maria p cruz 09 Aug '20

09 Aug '20

Dear Ge Wang! Because this mail is "only for Ge Wang" nobody else must answer it! My Windows 10 legal copy was infected with your ChucK server download of the chuck.exe, can you please dear Ge Wang explain to me and to everybody else who uses Windows 10 why your chuck.exe download file contains malware (a troyan perhaps?)). PS: the screenshots "with the infection proof"are not attached, they are sent to Ge Wang CCRMA e-mail inbox. I hope Ge, You can solve this error because I cannot use ChucK on Windows 10 now. Maria

GameTrak velocity
by Curtis Ullerich 08 Aug '20

08 Aug '20

Hi all, I'm experimenting with velocity patterns of GameTrak joysticks as event triggers. I'm curious if there's any prior art here. I'm working on a GameTrak class in ChucK that tracks the hand movement in space to add velocity and acceleration updates alongside the usual xyz position. In general, I've been surprised to not find much in the way of a GameTrak class/lib for ChucK, though I did find this one <https://github.com/rdpoor/chuck_performance_setup/blob/master/lib/game_trak…> .

10 times more expensive than what Spencer suggested, but I think worth checking this out anyway https://www.blokas.io/pisound/ I've been using it on my RaspPi 3 with ChucK in the last 3 months, and is great. I'm using they're Patchbox OS, and that is great as well.

This option is a quick way to easily get better audio quality from the Pi- in my experience the built-in sound card is unacceptably noisy for most musical purposes.

AutoCorr behavior
by Curtis Ullerich 27 Jul '20

27 Jul '20

As a preamble, I'll note that I posted a question on chuck-dev about AutoCorr/XCorr always crashing for me. This patch <https://github.com/ccrma/chuck/pull/150> seems to fix that. That said, I don't understand the results I get from AutoCorr. For periodic inputs, I expect to see periodicity in the output. For small FFT sample sizes, I see the expected peak at 0, and at large sample sizes I see a second peak at the end of the window. See example plots at 128 <https://i.ibb.co/BBZXgBB/autocorr-128.png> and 4096 <https://i.ibb.co/Mn5fty5/autocorr-4096.png>. That second peak is correlated with the window size, not the input frequency. Thanks to Mario for his gnuplot wrapper <https://github.com/mariobuoninfante/ChucK_various> that captured those plots. Here's the plotting code if anyone would like to repro: SinOsc s => FFT fft =^ AutoCorr c => blackhole; 4400 => s.freq; 128 => fft.size; 300::ms => now; c.upchuck(); Plot plot; "autocorrelation of 4400 hz, 128 samples" => plot.title; plot.plot(c.fvals()); 200::ms => now; Should I be using AutoCorr differently? Am I looking at the power spectrum or something, and not the correlation vector like I think I am? My current understanding comes from reading uana_extract.cpp many times with references like this <http://paulbourke.net/miscellaneous/correlate/>. Thanks, Curtis

Spencer Thanks a lot for your suggestions. Yes, I'm definitely considering OSC between peer-peer connect Raspberry Pi's. Still in testing mode with web chuck for now, and will see if it is the right setup for a low latency AV installation. Ideally I'd love to be able to load .ck files within javascript, driving visualisations via javascript libraries (I'm still looking into what's possible - have looked at p5.js and d3.js so far). Really useful that you raised the point on UDP. Would an OSC javascript library give the best of both worlds, webchuck to allow chuck drive the javascript visualisations, with OSC maintaining low latency syncronisation? I haven't tried yet, but this looks promising... https://github.com/colinbdclark/osc.js/ Another consideration I should perhaps point out, is this... I primarily am designing the AV installation for people to experience in person in a gallery space - hence the peer to peer set up as a priority. However since the first showing is in October, a second wave lockdown could mean zero footfall. As a backup, I'm looking to be able to run the whole installation on my webserver, so that for example a group of 4 friends could experience the installation on 4 laptops set up in a configuration of their choice in one of their homes. Amazing to think that this is not so far fetched, latency issues aside... I've run ChucK on a single raspberry pi 3 before, using the linux-jack or linux-alsa compilation option. I definitely have LOTS to learn about getting the most out this setup, so I'll be glad of any pointers you may have, and will keep you and Jack posted! warmest wishes micheal From: Spencer Salazar <spencer.salazar(a)gmail.com> To: ChucK Users Mailing List <chuck-users(a)lists.cs.princeton.edu> Cc: Bcc: Date: Mon, 20 Jul 2020 16:54:30 -0700 Subject: Re: [chuck-users] web integration Hey Micheal, As an alternative, if you intend for the sound to be coming from the Raspberry Pis and not a separate computer loading the webpages, you can run ChucK locally on the Raspberry Pi and communicate over OSC, though you may need to route OSC through Node as Im not certain that standard web browsers can send OSC over UDP natively.

Extending the software ??
by maria p cruz 23 Jul '20

23 Jul '20

Hello, I am Maria, I have been studying for some time at the University of Systems Engineering, and I have programmed some java and common lisp, in addition to C. I understand that SuperCollider and ChucK are open source environments, so I can extend mathematical algorithms, to compose algorithmically, but according to this: Which programming language is best suited to SuperCollider? Which programming language is most suitable for ChucK? ,Maria.

web integration

hi I'm developing an audiovisual installation to tour a number of arts centres in Ireland. I want to use ChucK to drive the audio elements, linking raspberry pi devices (up to 4) connected via hdmi to screens. The visuals I want to use browsers - probably firefox run off the RPi's. Each screen then displaying a different page from a javascript application run from one of the RPi's. I've done some initial check online of running ChucK wrapped in javascript, and this github page is the latest activity I can find https://github.com/aknuds1/chuck. I thought it best to check with the user community if 1) there are further developments on running ChucK in the browser 2) if the av setup I'm considering has been done before so I could perhaps link in and learn from others 3) if there are better setups that I should be following... Thanks and kind wishes micheal michealocathain.com

Hi Curtis Few months ago I was wondering the same and ended up with a temporary solution, a library that uses gnuplot to visualize waveforms. https://github.com/mariobuoninfante/ChucK_various Then it seems that with the latest version of ChucK is now possible again to have Chugins that deal with UIs, but I still have to find the time to look into it. I also mentioned sndpeek not too long ago, and I still thing that should be relatively easy to turn it into a Chugin.

Greetings Chuckists, Looking for validation on this before I change many, many lines of code: I'm noticing clicks and pops in running audio when I do something like this: Machine.add("thingOne.ck"); Machine.add("thingTwo.ck"); Machine.add("thingThree.ck"); Machine.add("thingFour.ck"); and also with Machine.remove(idNum); four times in a row. Question: Is this: Machine.add("thingOne.ck"); Machine.add("thingTwo.ck"); Machine.add("thingThree.ck"); Machine.add("thingFour.ck"); me.yield(); significantly different than this: Machine.add("thingOne.ck"); me.yield(); Machine.add("thingTwo.ck"); me.yield(); Machine.add("thingThree.ck"); me.yield(); Machine.add("thingFour.ck"); me.yield(); ??? The same for sporking shreds four in a row. Warmly, Mike -- Michael Clemow Artist/Composer/Sound Designer http://michaelclemow.com (he/him)

Depending on how HUGE the SndBuf files are, I have often loaded all of the files sequentially at the beginning, before I make any sound at all, into a single SndBuf, not to play them, but to get them into the cache. Then when the time comes to truly load them, they can be zero-disk loads. If they’re too big, this won’t work of course because you’ll exhaust your cache.

Hi Mario and thanks for your response! Is it possible for a shred to receive an float argument, from Command Line, that is the Gain of the shred and so gradually and manually faing the shred?

Shreds fade out
by Claudio Donaggio 31 May '20

31 May '20

Hi all! I was wondering if there is a way to smoothly fade out a shred. Example: from command line you add a shred with chuck + shred.ck and remove it with chuck - 1. But when you remove the shred or replace it gets cut off instantly. I am sure there is a way to dinamically scale the gain from 1 to 0 smoothly before remove the shred, but I do not have a clue on how to go about it... Thanks!

what does chuck —probe print out? Maybe you’re connecting to the wrong dac?? For reference, here’s an invocation script I used last time I did a multichannel performance: chuck -c8 -bufsize2048 -in2 --dac1 --adc0 INIT.ck That would have been an older version of chuck, but it worked then.

Command line multichannel weirdness (multiple versions!)
by mike clemow 14 May '20

14 May '20

Hi folks, Been a while, hope everyone is safe. I'm experiencing something very strange and feel I must be doing something wrong. (MacOS 10.14.6) Running chuck on command line like this: $ chuck --dac7 --out7 --channels4 --srate48000 --verbose --loop Then I run this file to test outputs: SinOsc s0 => dac.chan(0); SinOsc s1 => dac.chan(1); SinOsc s2 => dac.chan(2); SinOsc s3 => dac.chan(3); 1::second => now; Yields this error: [chuck](VM): NullPointerException: (UGen link) on line[3] in shred[id=1: speaker_tester.ck] Note: "line[3]"... it only thinks there are two dac channels. Indeed, I can only get sound out of dac.chan(0) and dac.chan(1). I get the same behavior in chuck versions 1.4.0.1, 1.4.0.0, & 1.3.6.0 I get the same behavior in different sound cards with 4+ channels out. BUT... the code works with 4 channels in miniAudicle! What is going on? What am I doing wrong? All best, Mike -- Michael Clemow Artist/Composer/Sound Designer http://michaelclemow.com (he/him)

Re: [chuck-users] chuck-1.4.0.1 (numchucks) released!

Hi, I second what Michael said, the streaming was really cool and interesting! About the new features and "libchuck", I am more than happy to help out as much as I can. I am not a C/C++ programmer, but I'm currently studying it. Recently I have done few little things in ChucK (mainly Chugins and easy bug fixes documented on github) and am getting more and more familiar with ChucK's source code, that is always useful. I suppose I could be of some help in some way. What I can do for sure though, is support with testing, mainly on Linux but also MacOS and Windows. Also, about the github repo, it seems like there are still old issues open even if they have been fixed. In case it can be useful I'd be happy to double check them so that we can then maybe close the cases.

Hey, thanks for the information. I'm currently learning DSP and the JUCE framework, so it sounds like I'd be able to incorporate ChucK there as well with the chuck.cpp file. Are there tutorials for that specifically? Or is it roughly the same as the Chunity implementation and I should be able to figure it out by looking at that?
