[chuck-users] WAV playback gets louder with each iteration

[Brian Robison]

Hi, ChucK users!  I'm having a problem that seems like it should have a
simple solution, but I can't figure it out.

Here's a program which plays a WAV (which is about 1.5 seconds long) every
two seconds, several times:

SndBuf buf;
"d3-fa.wav" => buf.read;
0.2 => buf.gain;

2000 => int notelen;

for (0 => int i; i < 20; i++) {
    0 => buf.pos;
    buf => dac;
    notelen::ms => now;
}

Each time (using ChucK 1.4), it gets louder, and I can't figure out why.
What am I getting wrong?

Thanks!
Brian

PS. you can find my d3-fa.wav here:
