miniAudicle console monitor on OSX El Capitan
by Anthony Becker 09 Jun '16

09 Jun '16

Hi everyone, When I upgraded my MacBook to El Capitan last fall, I found some problems with running miniAudicle. Well, no worries, I found Spencer's Git repository and downloaded the ChucK 1.3.5.2 beta, and everything works again... ...well, everything except for one minor detail. If I try to resize my Console Monitor window, the window itself resizes, but the content remains at the original size of the window, and won't take advantage of the larger window area. I have since upgraded to the final version of ChucK 1.3.5.2 fromhttp://chuck.cs.princeton.edu/release/, but I still have the same issue with the console monitor. Is there a configuration option or some other way for me to fix this? Or will I just have to wait for a new version of ChucK to come out? Thanks! Anthony

ChucK with RESTful APIs
by David MacDonald 06 Jun '16

06 Jun '16

Hi all, I'm new to ChucK and looking for a little advice. I'm currently working on a "podcast" bot which will generate new sounds/episodes nightly. I currently have a Ruby script organizing everything and handling the logistics of uploading the MP3 and updating the RSS feed. It runs asynchronously on a Raspberry Pi (Cron > Ruby > Chuck). Anyhow, I'd eventually like this little guy to be able to reach out on the web and have its sounds influenced by data it finds. So I was wondering if you all had any suggestions pulling things in from REST APIs like Twitter or news feeds or whatever. Is there a function for this in ChucK? Or would it be better to handle this stuff in Ruby and pass it to ChucK via a temporary text file or runtime arguments or something? Thanks, Dave

Chuck Newbie Advice - please assist
by Stephi LaReine 31 May '16

Hi guys, As a newbie I desperately need some accurate advice on a project I have set up. I am currently using an idea I found on the Instructables forum called Illumaphone by Bonniee. see link > http://www.instructables.com/id/Illumaphone-Light-based-Electronic-Musical-… I wish to use two 'illumaphones' individually controlled by two arduinos so I can vary sounds. I am also using Magic Music Visuals and OBS which is linked to a microphone to allow speech to be converted into text in real time. The idea is that the illumaphones outputs will be sent from the main line output of a macbook but I don't need the speech to make a sound just to trigger words. I am concerned that I won't be able to merge the arduinos sonic output together and whether I will be able to run Magic Music Visuals at the same time. I am using a usb microphone. I am also looking for ways to change the waveforms envelopes and filters in the code and I would be very grateful for any assistance in this so it doesn't muck up the code Many thanks, hope you can help :) Stephi *Stephi LaReine // Fashion & Lifestyle Blogger * StephiLaReine.com // Twitter: @StephiLaReine <http://Twitter.com/stephilareine> Instagram: @StephiLaReine <http://instagram.com/stephilareine> // Bloglovin <https://www.bloglovin.com/blogs/stephi-lareine-12421965>

Set adc sampling rate
by Guille Elias Alonso 15 May '16

15 May '16

Hi guys! I'm trying to make some analysis of the micro input and to do so I have to take my micro input with a sampling rate of 8000 Hz. I've checked my micro supports that (with chuck --probe) but in the doc I haven't found how to set the sampling rate of adc. Does someone know how to do that? Or does someone know where I can find some kind of API doc where everything is listed? In the ChucK language specification or in the Unit Generators Reference I cannot find much info about it. Thanks!Guille

In miniAudicle, it’s in the Preferences window. In terminal, the --srate switch sets sample rate: > chuck --srate8000 MyChucK.ck But both ADC and DAC must run at same rate. AND there has to be supporting hardware there to run at that sample rate. So native Mac coreaudio won’t allow for 8k. You could use the —silent switch, but then you lose the real timebase because ChucK then just runs as fast as it possibly can. You could plug in an iMic or other USB audio device that does support 8k, then it would all work. Use > chuck --probe to find out what sample rates are available.

Re: [chuck-users] Communicate with a C++ programme (Guille Elias Alonso)
by Perry Cook 13 May '16

It’s pretty old-school, but often my solution for this is to pipe text output of ChucK into stdin of the Cxx program in a terminal. You need to be sure to send to chout and not just use the <<< “PRINT THIS” >>>; form, because the latter prints to stderr, not stdout. Here’s a simple ChucK program that writes a random number to stdout every 16 ms. Below that is a very simple C program to read and report. You’d need to have your C++ program read from stdin and use the argument(s) accordingly. You’d invoke the whole thing like this: > chuck MyChucK.ck | myCProgram where myCProgram is your compiled C++ executable. // MyChucK.ck ChucK Program to write random numbers to stdout while (true) { 16::ms => now; chout <= Std.ftoa(Math.random2f(0.0,3.14159),4); // 4 decimal places chout <= "\n"; // newline chout.flush(); // be sure and do this!! } // END OF CHUCK PROGRAM TO WRITE FLOATS // myCProgram.c a C Program to read single floats from Stdin #include <stdlib.h> #include <stdio.h> #include <string.h> int main() { char inString[256]; float inVal; while (1) { fgets(inString,256,stdin); // read standard input inVal = atof(inString); // peel off float value inString[strlen(inString)-1] = 0; // kill the newline printf("Got it!! %s, %f\n", inString, inVal); // report!! } return 1; } // END C PROGRAM TO READ FLOATS > On May 10, 2016, at 2:09 PM, chuck-users-request(a)lists.cs.princeton.edu wrote: > > 1.

Everything about the analysis is written in Chuck. The analysis of the micro signal gives a single number every 16 ms, and this number has to be sent to the C++ programme but I don't know how I can connect the two parts. This application is highly time-sensitive so I need a fast way of communicating. > I had read about these OSC events but it seems it's only for Chuck programmes receiving input from the outside and I want just the opposite. I've also thought about some mechanism of shared memory between the Chuck programme and the C++ programme but I don't see anywhere some way of implementing that with Chuck. Do you have any ideas? > Thanks,Guillermo >

ICLI 2016 - Registration open
by thor 12 May '16

12 May '16

3rd International Conference on Live Interfaces School of Media, Film and Music - University of Sussex, Brighton. Dates: June 28th - July 2nd, 2016. Website: www.liveinterfaces.org Registration is now open for the International Conference on Live Interfaces in Brighton this summer. This biennial conference brings together people working with live interfaces in the performing arts, including music, the visual arts, dance, puppetry, robotics or games. The conference scope is highly interdisciplinary but with a focus on interface technologies of expression in the area of performance. Topics of liveness, immediacy, presence (and tele-presence), mediation, collaboration and timing or flow are engaged with and questioned in order to gain a deeper understanding of the role contemporary media technologies play in human expression. The conference consists of paper presentations, performances, interactive installations, poster demonstrations, a doctoral colloquium and workshops. Works engaging with the principles and assumptions governing interaction design, including perspectives from art, philosophy, product design and engineering are specially invited. Keynotes: - Stuart Nolan (magician) - Kristina Andersen (instrument maker) - Roman Paska (puppeteer) Workshops: - Magnetic Resonator Piano (Andrew McPherson) - The halldorophone (Halldor Ulfarsson) - Sound and Space: Performing Music for Organ and Electronics (Lauren Redhead and Alistair Zaldua) - A Practical and Theoretical Introduction to Chaotic Musical Systems (Tristan Clutterbuck, Tom Mudd and Dario Sanfilippo) - Making High-Performance Embedded Instruments with Bela and Pure Data (Giulio Moro, Astrid Bin, Robert Jack, Christian Heinrichs and Andrew McPherson) - Distributed Agency in Performance (Paul Stapleton, Simon Waters, Owen Green and Nicholas Ward) - Interfacing the Txalaparta Workshop (Enrike Hurtado) The conference, including performances and installations, will take place at the newly renovated Attenborough Centre for the Creative Arts. We will publish final performance, installations and paper programme when closer in time. There is a doctoral colloquium on Wednesday 29th of June and a Brighton Modular Meet on Sunday, 3rd of July. We look forward to welcome you to the University of Sussex for the ICLI conference this summer.
