granular music recommendations?
by AlgoMantra 23 Jul '24

23 Jul '24

Yo All....I'm trying to download and study some of the best music out there which features granular synthesis. I haven't heard much yet beyond Iannis Xenakis, but I'd love to know what your favorites are. Perhaps it would be worthwhile putting up a torrent of the same. If possible, kindly provide links to mp3 files or any other type of free downloads. (What do you think of Jaron Lanier's music?) http://www.jaronlanier.com/musicdownload.html cheers! ------- -.- 1/f ))) --. ------- ... http://www.algomantra.com

Scale & diatonic
by Hans Aberg 12 Oct '11

12 Oct '11

I have made a program, scale.ck, that admits one to work with scales, including tuning stretch, céleste tremulant, retune them, and then save to a file, with a line of code that can be pasted back into the source, available at next program startup. Scale tunings can be put into tuning banks, and otherwise defined by your favorite method. Details in the file. I have also updated my program for diatonic tuning systems, diatonic.ck. Just a few changes: adding some common tunings, fixing typos. The files are available here: http://www.math.su.se/~haberg/tuning_systems/ Hans

Granular synthesizer - Chuck language
by Wolfgang Gil 27 Oct '10

27 Oct '10

Hello, I'm working on a granular synthesizer using the language of Chuck (using miniAudicle). I would like to share the code with the desire to receive feedback from you. Please take a look at it if you like and feel free to modify it, use it, etc. .. I am also looking for an open-source pulse synthesizer and other microsound-based instruments. Thanks, open to collaborate. -- Wolfgang Gil http://www.wolfganggil.com -- Wolfgang Gil http://www.wolfganggil.com

LiSa "delay" in terminal ChucK vs. miniAudicle
by Christopher Jacoby 25 Oct '10

25 Oct '10

Hi, I've written a short test script (mostly taken from LiSa examples) using LiSa to create a simple delay. Can anyone explain to me why this works just fine when I run it through miniAudicle (version 0.2.0, ChucK v: 1.2.1.3), but when I run it from the terminal, I get basically the adc fed directly to the dac, with no delay. My chuck version is 1.2.1.4-dev-1. I'm assuming that something has changed in between those revisions that modified, but I can't seem to find a document online like this one<http://chuck.cs.princeton.edu/release/VERSIONS> that goes up through 1.2.1.4-dev-1. Any suggestions / recommendations for how I could get that working in the terminal? Here is my test code: adc => LiSa saveme => dac; > > > 1::second => dur len; > > len => saveme.duration; > > > 1 => saveme.loop; > > 1 => saveme.loopRec; > > len => saveme.loopEndRec; > > > 1 => saveme.record; > > 1 => saveme.play; > > > while (true) > > 1::second => now; > > > 0 => saveme.record; > > 0 => saveme.play; > Many thanks, Chris

Conversion from ASCII number to string letter
by Andrew C. Smith 16 Oct '10

16 Oct '10

Hey list, Is there a way to convert from a number to a string letter? Here's what I want: 97 => int number; <<< Std.SOMETHING(number) >>>; // console reads: "a" I know that I could create some function in chuck that just returns the ascii string value for all 128 possible numbers...but I don't especially want to. As some background, I'm hacking chuck to get the string.ch(int) method to work, in order to read in some form of notation that's not hard-wired into the code. Let me know if there's an easy way to make this work. Thanks. -Andrew

Frequency analysis using ChucK
by Sindhuri Kuppasad 16 Oct '10

16 Oct '10

I am an engineering (Computer Science) student and want to develop a *guitar tuning software*. The basic idea is to play a guitar string, read the sound through a microphone, *determine the frequency of the note that was played* and accordingly prompt the user to tune the string up or down. I wanted to know what capabilities ChucK provides to *analyse frequency* of the analog sound input and how it could be used in implementing the guitar tuning application. Also, are there any alternate approaches to obtain the frequency using ChucK? Regards, Sindhuri KN

Re: [chuck-users] Windows, drives, and Machine.add
by Rebecca Fiebrink 16 Oct '10

16 Oct '10

Thanks, but this doesn't work: ChucK parses this OK but then fails to find the file. Machine.add("/Users/rebecca/tmp.ck") works fine. Machine.add("C\\:/Users/rebecca/tmp.ck") produces [tmp.ck] no such file or directory (And re: previous posts, thanks, but Windows does handle forward-slash-style path names fine, without any need for escape characters. Hence the forward slashes in my strings. Escaped "\\" produces same results. Should've mentioned that before.) Has anyone actually gotten this to work in practice? The source code in chuck-1.2.1.3 that processes the argument to Machine.add is expecting to parse a filename and optional arguments using colons to separate the filename and arguments, but it also looks like it's trying to allow \: to escape a colon.

Try Machine.add("C\\:/Users/rebecca/tmp.ck") that will let the escape sequence parse parse \\ into \, and then the argument parser will see \: and leave your filename alone. -- rec --

Windows, drives, and Machine.add
by Rebecca Fiebrink 15 Oct '10

15 Oct '10

Have any ChucK windows users figured out how to accomplish Machine.add with a fully-qualified path name that includes the drive letter? Machine.add("C:/Users/rebecca/tmp.ck") results in error "[C]: no such file or directory" and Machine.add("C\:/Users/rebecca/tmp.ck") results in error [tmp2.ck]:line(2): unrecognized escape sequence '\:' I know you can leave off the C: entirely and it will work, but my concern is the situation where different files to be added live on different drives. Thoughts? Thanks! Rebecca
