Re: [chuck-users] Get audio samples of adc

You can use adc.last() or adc.chan(0).last() to access the most recent sample. Put that in a single-sample loop that writes to your input[] vector. -Julian On 2013-06-07, at 1:19 PM, chuck-users-request(a)lists.cs.princeton.edu wrote: > Re: Get audio samples of adc (fernando alonso)

Hey, You can collect the values from the ADC by calling it's .last() method. so for example: float values[32]; int i; for (int i;i<values.size;i++) { adc.last() => values[i]; samp => now; } I think what is confusing you is that chuck ugens works sample by sample and not by sending a vector like other languages. Does this help ?

I want to call a chuck server from my own client. To do so I need to know in what way the contents of the chuck file and the arguments are transferred. Are there any defined Result codes?

Using Wavelet Transform
by fernando alonso 14 May '13

14 May '13

Hi guys, I have implemented the Wavelet Transform in Chuck (to work with it moreover of FFT, etc). The code is: 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] => sum; 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]; } } } The only one problem is that I don't know how get from adc the values of the microphone input signal. I don't want to use FFT or similar. My implementation of Haar Wavelet Transform need this values. Anybody knows how get its? Thanks so much. -- Fernando Alonso Martín Lualobus(a)gmail.com http://roboticnaturalinteraction.com<http://www.roboticNaturalInteraction.com/famartin.html>

UAna autoCorr, xCorr and ZeroX

dynamic linking chuck howto?
by vilbjørg broch 29 Apr '13

29 Apr '13

hi there is there anywhere some sort of description of how to do the dynamic linking to other libraries? Eg. specifically I would very much like to work with the c++ library "Eigen" within a chuck file, is this possible?, if yes are there any hints about how to do this. Already for a while `I read on this page http://chuck.cs.princeton.edu/doc/program/stdlib.html that the documentation is coming, so maybe there is a drawer to pull it out of.?? Greetings Vilbjørg

midi ports
by Philipp Kroos 24 Apr '13

24 Apr '13

Hi! I'm new to this list (and again to ChucK), so hello first ;) Is there a way to keep midiports 'open'? I can specify the number of audio io's when starting chuck --loop, can I do the same with midi io? I'm using LASH on linux. My objective is to start ChucK and connect a midikeyboard to it. In previous versions (used dracula before) a midi-port came up in LASH when I started a .ck-file that used a MidiIn-object, and stayed open. In the current version, the ports disappear once the program finishes. Thanks for any hints! - Philipp
