The ChucK Tutorial

This tutorial was written for the command line version of ChucK (currently the most stable(穩定的) and widely supported). Other methods of running ChucK includes the miniAudicle (now on all major platforms) and the Audicle (in PRe-pre-alpha). The code is the same, but the way to run them differs, depending the ChucK system.

…generate a sine wave and send to the speaker…

…connecting audio processing modules (unit generators) and having them work together to compute the sound.

The above does several things:

In ChucK, when one unit generator is ChucKed to another, we connect them. We can think of this line as setting up a data flow from ‘s’, a signal generator, to ‘dac’, the sound card/speaker. Collectively(集體的), we will call this a ‘patch’.

…we simply have to “allow time to pass” for data to be computed…time and audio data are both inextricably(密不可分) related in ChucK (as in reality), and separated in the way they are manipulated(操縱).

let’s generate our sine wave and hear it by adding one more line:

Let’s now run this (assuming(假設) you saved the file as ‘foo.ck’):

For now, we can just take the second line of code to mean “let time pass for 2 seconds (and let audio compute during that time)”. If you want to play it indefinitely(無限制地), we could write a loop:

In ChucK, this is called a ‘time-loop’ (in fact this is an ‘infinite time loop’). To stop a ongoing ChucK program from the command line, hit (ctrl - c).

Now, let’s try changing the frequency randomly every 100ms:

Two more things to note here.

目前運行的結果是有并不規律的聲音產生，這就是那個時刻變形的聲波

Now let’s write another (slightly longer) program: (these files can be found in the examples/ directory, so you don’t have to type them in)

Name this moe.ck, and run it:

Now, make two copies of moe.ck - larry.ck and curly.ck. Make the following modifications(修改).

Run all three in parallel:

What you hear (if all goes well) should be ‘phasing’ between moe, larry, and curly, with curly emitting(發出) the lower-frequency pulses(脈沖).

ChucK supports sample-synchronous concurrency(并發性), via the ChucK timing mechanism(機制). Given any number of source files that uses the timing mechanism above, the ChucK VM can use the timing information to automatically(自動地) synchronize(合拍) all of them… Note that each process do not need to know about each other - it only has to deal with time locally. The VM will make sure things happen correctly and globally.

A large collection of pre-made examples have been arranged and provided with this distribution in the /doc/examples directory, and are mirrored here
