Hi,
I tried to follow Carl's suggestion to record a wav file but it didn't work
for me. The first time I change the check box the wav file sink will stop
working forever. File sinks works fine. Will Martin's suggestion work for
wav files or does anyone have another suggestion to record wav files only
when the checkbox is enabled?
I've attached my flowgraph.
Cheers,
Murray

</div></div>Write a small Python block that takes a setter, then input a button<br>
state through a QT selector. This block will only allow samples flowing<br>
through when you input a certain state.<br>
