I didn't think it was really a digital notch / bandpass filter but thought it's only a couple quid. LOL it is and works realtime not on a recorded file! Put the bandpass to a slot at minimum Herts with a 100 Hz width and put it on your chest where your heart is. Mesmerizing listening to heart with no other sound. Use it now to keep an eye on unusual noises from my marine diesel. Thanks man I owe u more than £2
Works well This little app actually worked quite well.. I laid it on top of a k2 with all filters turned off. However through my headphones I was able to go very narrow to effectively filter out adjacent cw signals with the dsp app. Great!
Excellent at what it does, but what it does not do is stay running as a background service when my screen goes to sleep or when I switch to other apps. It's still a pretty cheap investment for experimenting with sound filtering to see if purpose specific hardware would be right for your application.
Works exactly as advertised Used it to try a cancel a buzzing noise on a specific frequency, works great.
Does what it says A good app that allows you to filter sound from MIC and listen it with a minimal delay. Missing only customization of waterfall, the rest is very good.
Average Hi, Had to reinstall after Marshmallow upgrade. Thanks. God bless. Aaron
