chuck

Chuck is a masculine given name or a nickname for Charles or Charlie. It may refer to:

ChucK is a concurrent, strongly timed audio programming language for real-time synthesis, composition, and performance, which runs on Linux, Mac OS X, Microsoft Windows, and iOS. It is designed to favor readability and flexibility for the programmer over other considerations such as raw performance. It natively supports deterministic concurrency and multiple, simultaneous, dynamic control rates. Another key feature is the ability to live code; adding, removing, and modifying code on the fly, while the program is running, without stopping or restarting. It has a highly precise timing/concurrency model, allowing for arbitrarily fine granularity. It offers composers and researchers a powerful and flexible programming tool for building and experimenting with complex audio synthesis programs, and real-time interactive control. ChucK was created and chiefly designed by Ge Wang as a graduate student working with Perry R. Cook. ChucK is distributed freely under the terms of the GNU General Public License on Mac OS X, Linux and Microsoft Windows. On iPhone and iPad, ChiP (ChucK for iPhone) is distributed under a limited, closed source license, and is not currently licensed to the public. However, the core team has stated that it would like to explore "ways to open ChiP by creating a beneficial environment for everyone". The ChucK Operator (=>) that can be used in several ways to "chuck" any ordered flow of data from left to right. ChucK standard libraries provide: MIDI input and output. Open Sound Control support. HID connectivity. Unit generators (UGens) - ie oscillators, envelopes, synthesis toolkit ugens, filters, etc. Unit analyzers (UAnae) - blocks that perform analysis functions on audio signals and/or metadata input, and produce metadata analysis results as output - ie FFT/IFFT, Spectral Flux/Centroid, RMS, etc. Serial IO capabilities - ie Arduino. File IO capabilities. // signal graph (patch) SinOsc s => JCRev r => dac; .2 => s.gain; // dry/wet mix (for reverb) .1 => r.mix; // an array of pitch classes (semitones) [ 0, 2, 4, 7, 9, 11 ] @=> int hi[]; // do forever: while ( true ) { // choose a note, shift registers, convert to frequency Std.mtof( 45 + Std.rand2(0,3) * 12 + hi[Std.rand2(0,hi.cap()-1)] ) => s.freq; // advance time 120:: ms => now ; } Graham Morrison, (2009) Generate choons with Chuck. Tired of the same old music in the charts, we create our own music from a series of pseudo random numbers.
