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!
