ChucK Ubuntu package

Hi, I just noticed that the ChucK Ubuntu package is quite old (v 1.2). Would it be possible to update it? What's the procedure for that? Cheers, Mario

FaucK - issue with 'v' methods
by Mario Buoninfante 19 Mar '19

19 Mar '19

Hi, I'm using the FaucK chugin and I don't know why when I use the 'compile' method to load a Faust script, then I cannot change the parameter in it (ie my_faust.v("param", value) ). The same script, when 'embedded' in the ChucK code using 'eval', works fine. I also tried specifying the entire path of the parameter, but doesn't seem to work (ie "Folder/MyFaust/param"). Does anyone have the same issue? I tried on MacOS Sierra. Cheers, Mario

Hi, Is there any plan to allow the FaucK chugin to deal with more than 1 input and output? Cheers, Mario Sent from my WIKO U PULSE LITE

Re: [chuck-users] Convolution Reverb (Posed by: Julien Saint-Martin)

If the impulse response is short enough, or real-time isn’t important, then the FIR chugin can be used. FFT-based convolution is possible using the FFT/iFFT UANAs, but latency and real-time are issues. To deal with that, It would be possible to factor into a nice systolic topology using shorter FFTs and delay lines to line everything up. I don’t know of a specific chugin or example other than those. Someone should write one :-)) Prc Sent from my iPhone > On Mar 1, 2019, at 9:00 AM, chuck-users-request(a)lists.cs.princeton.edu wrote: > > Send chuck-users mailing list submissions to > chuck-users(a)lists.cs.princeton.edu > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.cs.princeton.edu/mailman/listinfo/chuck-users > or, via email, send a message with subject or body 'help' to > chuck-users-request(a)lists.cs.princeton.edu > > You can reach the person managing the list at > chuck-users-owner(a)lists.cs.princeton.edu > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of chuck-users digest..." > > > Today's Topics: > > 1.

Convolution reverb in ChucK ?
by Julien Saint-Martin 01 Mar '19

Hi, Is there a way to have a convolution reverb running inside ChucK ? I searched inside the chugins (Faust, Ladspa...) but didn't find anything. Happy Chucking! Julien

Gen10 issue with odd harmonics
by mario buoninfante 23 Feb '19

23 Feb '19

further testing shows that it's not about the odd harmonics, from the 5th harmonic (6th partials) onwards, sometimes you get unwanted sidebands with odd harmonics, sometimes with even ones. I'm monitoring the output (DFT) with Baudline and I tried driving Gen10 at different frequencies. -- Electronic Musician, Creative Coder, QA Engineer https://vimeo.com/creativecodingsalerno http://mbuoninfante.tumblr.com/ https://github.com/mariobuoninfante https://bitbucket.org/mariobuoninfante/

Gen10 issue with odd harmonics
by mario buoninfante 23 Feb '19

23 Feb '19

Hi, I found out that Gen10 has an issue with dealing with odd harmonics (not fundamental). It's easy to repro simply taking the example code and using the following coefficients instead: g10.coefs( [0., 0., 0.5] ); - shows the issue g10.coefs( [0., 0.5, 0.] ); - doesn't show the issue Hooking ChucK up to a spectrum analyzer it's easy to see the difference. In case there are odd harmonics, there are a lot of unwanted partials/sidebands, instead of having only the components specified in .coefs(). Gen9 doesn't seem to have this issue.

Re: [chuck-users] Routing SndBuf (Skot)
by Perry Cook 19 Feb '19

19 Feb '19

I don’t remember SndBuf ever being multichannel. In fact, there is a SndBuf2 just for stereo. That UG can be chucked to dac for auto stereo, or allows access to .chan(#) for arbitrary routing. SndBuf mixes everything down to mono, and I fear there is no support for > 2 channels via SndBuf. If my statements above are true, then Someone could do us all a cool favor by making a SndBufN chug.

Hi, I think you should use SndBuf2 instead of SndBuf.

Routing stereo sound file to dac channels
by Scott Smallwood 18 Feb '19

Dear chuckians… This is bizarre… I was sure I have done this in the past, but it isn’t working and now I’m a bit flummoxed…. Any ideas here? PS: I’m trying to route channels 0 and 1 of a stereo .wav file to dac channels 2 and 3. Should be simple. So why doesn’t this work?? I realize that I could just spit it into mono files… but why? I thought SndBuf supported up to 8 channels. — SndBuf sb; //read in stereo sound file "snd/squeakies/bell_4.wav" => sb.read; //works - and routes channel 0 of sb to dac.chan(3) sb.chan(0) => dac.chan(2); //doesn't work - claims NullPointerException sb.chan(1) => dac.chan(3); 1::minute => now; —ss [ - ] Scott Smallwood <http://www.scott-smallwood.com/> - Associate Professor - University of Alberta [ - ]
