Is there plans for something like "include"
by Mike McGonagle 05 Jan '06

05 Jan '06

Hello everyone, I was wondering if there were plans to implement a method for "including" a file in another? Something on the order of C's include, or Java's import? Also, if this is not in the plans, then is there anyone who is using something like either "m4" or C's preprocessor to merge file prior to "feeding" ChucK? Is there a way to "pipe" the preprocessed files into ChucK without having to write that stuff to another file? Basically, I have some objects, that I would like to work with accross several files. and rather than having to explicitly put the code into each file. Thanks, Mike

How to read large data files
by Mike McGonagle 05 Jan '06

05 Jan '06

Hello all, I recently found ChucK, and have started to work with it in putting together some music. I am trying to use fractal data as a control for various parameters. I rewrote my fractal program in ChucK, but because of how the floats are of limited percision, I am getting different results than the same program written in C. I had thought about two (three?) different approaches to solving the problem, the first would be to use my C program to generate the fractal data, and write it to a file. My program can write this data to an audio file, which would then be imported into ChucK. BUT, it would appear that it is not possible to access the underlying sample data from a 'sndbuf' object. I had looked to see if there was a generic function to read raw data from a disk file, but could not find anything. Also, would this be practical to read, as these datafile can have as many as 20,000 samples per file, these into an Array? How much overhead is there in using an array of floating point values on the order of 20,000 elements? The last idea would be to write a UGEN object in C++, and then recompile ChucK to include this new object. Is there a limitation to how many outputs a UGEN can produce in a single iteration? Several of the fractals that I am working with output more than one value per iteration (each output values represents a different variable in the fractal algorithm). Any suggestions would be appreciated. Thanks.

question about input detector from adc (MIC)
by 劉建志 03 Jan '06

03 Jan '06

Dear all, I would like to detect "sound" input from MIC (adc). It means that if any sound occure, one event or anything should be done. My thought is that: adc => gain g => blackhole; 1 => g.gain; g.last() => float x; while( true ) { if ( std.fabs(x) == 1. ) <<<x>>>; } But the x is always 0. So how to do it?? Thanks a lot!! Lewis

fun dur GetT() rises to invalid type
by eduard 18 Dec '05

Hi there, I have a osc meta-instrument wich has a function to get the unit_time to advance. Something like: public class oscInstrument { // some members here // .... fun dur GetT(){ return T_}; } It compiles fine, but when used in the following manner: oscInstrument myInstrument; while(true) { //do_something //... noteDuration::myInstrument.GetT() => now } it rises the following error: invalid type 'oscInstrument' in postfix of dur expression... (must be of type 'dur') . However if I do the following: dur T; while(true) { //do_something myInstrument.GetT() => T; noteDuration::T=> now } everything works fine. Any ideas? Thanks, Eduard

sinosc and phase_offset
by michael breitenbach 18 Dec '05

18 Dec '05

hi, this code: 60 => std.mtof => float freq; sinosc m1 => sinosc c1 => dac; freq => m1.sfreq; freq => c1.sfreq; while (1) { m1.last() => c1.phase_offset; 1::samp => now; } causes this error: operation failed (sorry)...(reason: line(10): class 'sinosc' has no member 'phase_offset') why??? - in the doc is a input for phase_offset in sinosc micha

performance under linux
by Atte André Jensen 18 Dec '05

18 Dec '05

Hi I retested my midi setup stuff (http://www.atte.dk/midi.tgz) with the latest/greatest under linux, and there seems to be a quite large latency. About maybe 100ms at least way too large to be playable. However it seems that cpu usage is more relazed. Am I wrong in expecting improvements in the new release under linux, or am I missing something? Looking forward to any response... -- peace, love & harmony Atte http://www.atte.dk

sporking member functions
by Atte André Jensen 18 Dec '05

18 Dec '05

Hi I tried the attached old (in other aspects not-working) code in the latest/greatest, but it seems that sporking a member function is still causing an exception. Am I right? Any plans on changing this? -- peace, love & harmony Atte http://www.atte.dk
