Thanks for the fast reply. I have write this code: 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]; } } } 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! 2013/6/7 Aurélien Bondis :

Hi, I don't know what a wavelet transform is, but can't 'adc =>' work ? or 'LiSa' do what you need? (http://chuck.cs.princeton.edu/doc/program/ugen_full.html#LiSa) Sorry if I did not understand the question... Aurélien.

Hi,

I want to program de Wavelet Transform, and for it I need to get the audio samples. Do you know some way to get the audio samples?

Thanks.
