Hi, It seems like SndBuf deals in a different way with audio files which have different sample rate. I tried this simple program where the 2 audio files samples are compared (perc.wav and perc2.wav which are the same file one 44100 and the other 48000 Hz sample rate), so that I can check if they are different. it looks like for SndBuf they are different. am I missing something? does SndBuf convert in some way the audio files? cheers, Mario SndBuf sample => blackhole; SndBuf sample2 => blackhole; sample.read("perc.wav"); sample2.read("perc2.wav"); <<< sample.length(), sample2.length() >>>; 0 => int err; for(0 => int c; c c){     if((sample.valueAt(c) - sample2.valueAt(c)) != 0){         1 +=> err;     } } <<< err >>>;
