[chuck-users] playing SndBuf backward

12 Feb 2020

      Sorry PRC it doesn't work: When i set "buf.rate" to 1.0 and  "buf.pos"  to 0,  it does but not the other way around....

me.sourceDir() + "aeiou.wav" => string filename;
if( me.args() ) me.arg(0) => filename;

SndBuf buf => dac;

filename => buf.read;

buf.length() => dur totalelengte;
buf.samples() => int samples;

samples => buf.pos;
-1.0 => buf.rate;

samples::ms => now;

You can set the .pos to wherever you like, and set the .rate to a negative number.  The sample will happily play backward to zero and stick there (unless you have .loop set).

Thanks again Mario,
I have another question:
Can you recommend a procedure to address individual samples of a wave-file you read into the SndBuf.
I discovered a way to play a part of a wave file starting at a certain point using ".pos".
I also wonder if there's a way to play it backwards (reverse).
Cheers,
herman
