Um. that works.

So does this:

SndBuf s => blackhole;
"/home/forrest/chuck/examples/basic/om.wav" => s.read;
float samples;
0 => int i;
while (s.pos() < s.samples()) {
<<< s.last() >>>;
s.pos() => i;
(s.valueAt(i)) => samples;
<<< samples >>>;
samp => now;

}

I was having trouble trying to read a sndBuf like an array, or put its contents into an array.

Maybe I was reading numbers off the end of the file. Declaring

'float samples[]; '

and doing

's.valueAt(i) => samples[i];'

got me a 'Null pointer' error.

Stumbling over syntax, I guess. Thanks for help!

know why it wouldbe broken dependent on the dac, however.

For fun you might try something like this, just to verify that the
valueAt() function is what’s busted.

SndBuf s => blackhole;
“Fred.wav” => s.read;

while (s.pos() < s.samples()) {
<<< s.last() >>>;
samp => now;
}
