Squelch in Audio mode

Fantastic software!

Documentation page shows squelch option, but it is not visible in latest download of MNM4SDR.

I understand there is a version of rtl_fm that will pad output with 0's when no audio present, so it should be possible to stream audio with squelch option. Is this something that can be enabled or am I doing it wrong in 1.0.0.8?

Also are you accepting donations for your work? I'd like to contribute.

Thanks,
You are right, I've removed squelch in the last version because it is not possible to retain audio stream if there wasn't input from rtl_fm. So having squelch option in MNM4SDR seems pointless. Zeroing doesn't do the trick, it would be better to have white noise on the rtl_fm output whenever squelch cutoff original audio. As workaround I would try to set equalizer of audio player in order to suppress audio noise. MNM4SDR is free software and I haven't thought about donations so far. I am glad to hear you are enjoying in MNM4SDR and please feel free to report any problem, bug or suggestion you have.
