Hi Dan,

Thanks for the response, but it seems like burst tagger would not work
in this case because I am working with audio. What I want is when
power squelch is triggered demod a NFM signal and then save it to a
wav file with the time power squelch was triggered.

You can try keeping power squelch's gate to false (so that you will get zero samples) and then use it as a trigger for "burst_tagger" after doing some math manipulations. This along with a "tagged_file_sink" should work.

Please look into "gnuradio/examples/tags" for examples.

Thanks
