minor bug when saving an example with "save as"
by Steve Morris 08 Oct '13

08 Oct '13

Hi. I'm new to ChucK and love it but I would like to report what I think is a minor bug. I'm on a Mac running OSX 10.8.5. miniAudicle "about" reports: version 1.3.0 (gidora) Copyright (c) Spencer Salazar ChucK: version 1.3.2.0 (chimera) 64-bit Copyright (c) Ge Wang and Perry Cook http://chuck.cs.princeton.edu/ Bug report: Note: this is clearly low priority and minor, more in the category of an annoyance. I opened an example then saved it with "save as." Then I edited it then tried to save the changes. A dialog reported the file was read only. I checked the file with info and the file has Read & Write permission. I can overwrite it with "Save As" but Save refuses to save. I suspect that the example was read only and it kept that attribute in some file state variable. If true this is wrong in two ways, first it should have updated the local state to match what it wrote and second it should not depend on historical information. Even if the file was read-only when opened that may have changed. This is a multitasking system and some other task (me in finder for example) might have changed the permissions since the file was opened. I believe the correct behavior would have been to attempt to write the file and check the error status of the write. Best regards and thanks for a wonderful tool. -Steve Morris aka zencuke

Wah-Wah "pedal"
by Perry Cook 08 Oct '13

08 Oct '13

Hey all, There was some recent discussion over on the STK users list, about implementing a Wah-Wah pedal. I hacked together a simple one based on experiments and data that Julius O. Smith did using his own personal CryBaby Pedal. For more on that: > https://ccrma.stanford.edu/realsimple/faust_strings/faust_strings.pdf Here's my quick version in ChucK, using just his three data points, interpolating between. Enjoy!! I'm going to hook it up to a MIDI pedal shortly.

WvOut2 bit depths
by Dan Trueman 06 Oct '13

06 Oct '13

hey, i'm wanting to use WvOut2 to write 24bit or higher sound files, but am not finding a way to do it, though the documentation says it is possible. well, it seems to write Matlab files to high bit depths, so if anyone knows how to convert those to wav or air, that would also get me where i need to be. any ideas? thanks! dan

05 Oct '13

Howdy, chuck 1.3.2.0 + miniAudicle 1.3.0 have been released: http://chuck.stanford.edu/release/ Our first release in a year is an exciting one. In anticipation of a number of ChucK-based computer music education initiatives (the forthcoming book "Programming for Musicians and Digital Artists" and Coursera course of the same name), we have added a number of conspicuously absent features and libraries, alongside cleaning up a large number of The most significant change is to formally release chuck as an installer package on Mac OS X and Windows platforms. These installer packages include chuck, miniAudicle, related example files, and the standard set of chugins. (Separate installation of these components is possible but discouraged and not necessarily supported.) Linux, for the time being, is still released as separate source distributions. SerialIO will allow ChucK programmers to easily interact with serial-based hardware devices such as Arduino. A number of string processing utilities have been added. Furthermore, the clear.vm command will enable more dynamic on-the-fly development with public classes. In miniAudicle, the underlying application core on Windows/Linux has been completely rewritten in Qt, greatly improving stability and overall experience.

ChucK on a Beaglebone Black
by meino.cramer＠gmx.de 01 Oct '13

01 Oct '13

Hi, I managed to compile chuck on a beaglebone black (using Gentoo). Most of the example files play well, but there are some files, which produce a somehow interrupted sound. If this would be due to too less processing power of the CPU (ARMv7 Processor rev 2 (v7l) at 1GHz) -- how can I verify it? What else could produce this problem? Best regards, mcc

This release looks very interesting. I'm intrigued by the Serial stuff, wonder if I can connect to my monome? I ran the installer, and a chuck program appeared under /usr/bin, however I wonder where the examples end up? I can't find serial examples on the ChucK site... downloading the source bundle to see if I can find some examples there. Cheers! /Stefan

Binaural Processing in ChucK - requires headphones - really works!
by Rich Caloggero 06 Aug '13

06 Aug '13

http://www.mit.edu/~rjc/binaural/ Goto the above and download “chuck-sources.zip”. Unzip and look at the readme.html file; should get you running. The program requires a file called “music.wav” in the directory from which it is run (forgot this in the docs). If given a stereo file, only the left channel is processed. Anyone have any ideas on how to implement crosstalk cancelation? I’ve tried to read the relevant papers but cannot understand the mathematics. I’ve got something in here (which is turned off by default) based on simple feedback network of inverter and delay, but it doesn’t really work. Perhaps adding filtering will help, but haven’t tried this yet. Ping me with questions; I’ll try and answer the best I can. -- Rich

OSC pattern matching
by dparson 26 Jul '13

26 Jul '13

It's been a while, so apologies in advance if this topic has come up lately. Last time that I wrote an OSC receiver in ChucK, the code had to match the incoming address pattern verbatim. There was no way to apply pattern matching, e.g., a regular expression, to match the incoming string. Also, I don't think that there was a way to match a prefix of the incoming string, after which one could in theory write one's own pattern matcher on the remainder of the incoming string. Little time for that, anyway. Is it (still) necessary to match the incoming OSC pattern string, literally, in its entirety? My solution last time was to spork a separate shred to match each incoming literal string in its entirety. That approach does not fully solve the problem at hand. Thanks. Dale (Acoustic Interloper)

Online Manual
by Rich Caloggero 08 Jul '13

08 Jul '13

http://booki.flossmanuals.net/chuck/_full/ Is this manual current / being actively updated? If so, then there is a problem throughout with how characters are represented. It seems that perhaps the text may have been extracted from some graphical design program because some character combinations "(the characters “f” followed by “i” in this example) are replaced by a single weird character. When seen visually this may look like the two-character sequence “fi”, but to a screen reader or to anything else that processes text, this looks like a weird unpronouncible mess. My screen reader reads the word “file” in this example as: [character 64257[le The stuff in brackets is what the screen reader says when it encounters the weird character. Hope this can be fixed. Reading the manual in its current state is much less fun than it could be. Thanx for a great language and community. -- Rich %>chuck moe.ckIn this case, ChucK will run whatever is in moe.ck. You can replace moe.ck with the name of another ChucK ﬁle. If this script is a just a loop that never ends then we need to stop ChucK eventually. Simply press CTRL-C (hold control and press c). This is the ”kill process” hotkey in the terminal. Some ﬁrst things to try is to test the concurrency (running multiple ChucK ﬁles in parallel) are moe, larry, and curly.

EspGrid 0.42
by David Ogborn 10 Jun '13

10 Jun '13

Dear friends, I am pleased to announce the official release of version 0.42 of the EspGrid software - the synchronization and sharing software for laptop ensembles I have developed around the Cybernetic Orchestra at McMaster, during the project "Scalable, Collective Traditions of Electronic Sound Performance" (supported by Canada's Social Sciences and Humanities Research Council, SSHRC). The software and some additional helpful files (code/patches) can be downloaded here: http://esp.mcmaster.ca/EspGrid-0.42-OSX-10.7.zip Over the course of the past year, earlier versions of the software have been presented at the Toronto Electroacoustic Symposium, the Audio Engineering Society Convention in San Francisco, and most recently, the live.code.festival in Karlsruhe, Germany. This 0.42 release is a "clean-up release" - with better stability and synchronization. EspGrid has been developed around the ideas of neutrality and hybridity with respect to the languages and environments employed by laptop and live coding performers. The EspGrid application "sits in the background" and takes care of clock synchronization, to a large degree independent of the diverse and multiple "foreground" environments in which performers/creators work. Another participant in the live.code.festival session (chair Alex McLean, if I recall correctly) provided a perfect example of the intent of the EspGrid software: three electronic musicians find themselves on a train together; despite all using different languages/tools to make their music, they each fire up EspGrid and instantly share a tight common clock and a metronome that anyone can control. Jamming ensues... The EspGrid software is being made available to community as free and open source software (GNU public license version 3). The code base of the software includes a large and growing number of unit tests, and development should proceed according to the principles of test-driven development. The rudiments of a help/documentation system are in place. Binary executables exist only for Mac OS X at the present moment but the Windows and Linux ports of the software are the highest, immediate priority following this release. Windows and Linux users in mixed laptop ensembles don't need to wait for these ports however: there is a "side chain" mechanism that allows users/machines without a running grid to piggyback on a user/machine that is running the grid. To get/browse the source code, visit the software's Google code site at: http://code.google.com/p/espgrid Enjoy - and feel free to get in touch for help/issues with the software. I hope that some of you will find this useful, and look forward to working with you on the (gradual) evolution of this tool!

Re: [chuck-users] Get audio samples of adc (fernando alonso)
by Perry Cook 09 Jun '13

09 Jun '13

Either is fine, in fact the samples would be identical in this example. However, if you wanted to apply a gain scaling to the samples coming from adc (as part of a more elaborate patch, for example), then the gain labeled "input" would be the place to do it (I'll tell you why soon). In the example I gave, we could set input.gain to 32768.0 then do the cast of input.last() to int, saving the multiply. For that, you'd need to connect adc through the Gain UG and to blackhole, because it doesn't update/compute without that. Why wouldn't we just change the gain of adc? Well, as a matter of best practices, that is a very bad idea. Turns out that since adc is a persistent and unique UG (like dac and blackhole), as long as the VM runs, the gain change on adc is permanent and global! Imagine how surprised another shred might be if it used adc and found the samples ranging from -32767 to 32768. Bad idea, so I make my students always connect adc to a Gain UG, just avoid the temptation of operating on adc directly. Also, if you connect adc => blackhole (or adc => dac), that connection is also global and permanent, even though the shred that did it might end. So again, operating on adc directly is not good practice. adc.last() is perfectly fine at all times, but I just make my students avoid all use of adc directly. Hope this helps, PRC

Re: [chuck-users] Get audio samples of adc

You can use adc.last() or adc.chan(0).last() to access the most recent sample. Put that in a single-sample loop that writes to your input[] vector. -Julian On 2013-06-07, at 1:19 PM, chuck-users-request(a)lists.cs.princeton.edu wrote: > Re: Get audio samples of adc (fernando alonso)

Hey, You can collect the values from the ADC by calling it's .last() method. so for example: float values[32]; int i; for (int i;i<values.size;i++) { adc.last() => values[i]; samp => now; } I think what is confusing you is that chuck ugens works sample by sample and not by sending a vector like other languages. Does this help ?
