I was told that in order to smoothen my slow-rated sample playback i should use .interp. In the script i added it but I don't hear any difference. Help!

me.sourceDir() + "sound.wav" => string filename;

if( me.args() ) me.arg(0) => filename;

SndBuf buf => dac;

filename => buf.read;

2 => buf.interp;

.2 => buf.rate;

buf.length() => now; // play him

1::ms => now; // wait a bit

1 => buf.loop; // loop homer now

buf.length() => now; // for 2 seconds

.1 => buf.rate;
