Re: [chuck-users] chuck-users Digest, Vol 161, Issue 8

hey Casper thanks! I think the issue may also be in the statement if (i%iMax > jCount ) 0.0 =>s.gain; which is not the same as if (now%iMax > jCount ) 0.0 =>s.gain; because I don't think "now" increments at the same rate as i (I wonder if now increments one sample at a time, rather than .1 ms at a time, then they become equivalent, thus your fix.). Anyway, not sure--haveto try this at home. Cheers, Charlie On Thu, Jan 31, 2019 at 12:00 PM wrote:

I think I found it: .1::ms is not the same as 1::samp You do in both scripts .1 ::ms => now, but in the second variant, this means now will have increased by 4.1 samples, instead of 1 unit (depending on your samplerate). I could get the same sound from both scripts by changing .1::ms => now to samp => now;

Best, Casper

Hey folks, I'm puzzled why these two shreds don't make the same sound. I created a simple bit crusher using an integer as an index and then using time as an index; I thought these were equivalent but they aren't. I wonder if this is because the integer increments at a different rate than the sampling rate? Any guidance on this gratefully received! Thanks,

Charlie

First shred: //---------------------------------------------

SinOsc s => dac;

110 => s.freq;

0 => int i; 250 => int iMax; 0 => int jCount;

while (true) { i++;

// if (i%130 == 0 || i%201 ==0 || i% 737 == 0) 0 =>s.gain; if (i%iMax > jCount ) 0.0 =>s.gain; jCount++; if (jCount > iMax) 0 => jCount; // 1::samp => now; .1::ms => now; 1 => s.gain;

}

//---------------------------------------------

second shred:

//---------------------------------------------

SinOsc s => dac;

110 => s.freq;

0::samp => dur jMin; 250::samp => dur iMax; 0::samp => dur jCount; 1::samp => dur jDelta;

while (true) {

if (now%iMax > jCount ) 0.0 =>s.gain; jCount+jDelta => jCount; if (jCount > iMax) jMin => jCount; .1::ms => now; 1 => s.gain;

}
