fun int[] discreteHaarWaveletTransform( int input[]){
int sum, difference,length,i;
int output[input.cap()];
for ( (input.cap() >> 1) => length ; true ; (length >> 1) => length) {
for (0 => i; i < length; ++i) {

input[i * 2] - input[i * 2 + 1] => difference;
sum => output[i] ;
difference => output[length + i];

if (length == 1) {
return output;
}
//Swap arrays to do next iteration
for (0=>i; i < (length<<1); i++){
output[i] => input[i];
}
}
}
For this reason I need the int input [] array relating to adc input
samples. I need to extract the "raw" values of the input (without
FFT). I have test with something like that:
adc.chan(0) => UGen inputMic;
Thanks for the help!

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