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
Meh I used a headphones/mic splitter adaptor and a cable to plug my yaesu ft-817nd directly up to the phone in an attempt to use this app for its intended purpose, I.e. ham radio, and at least on ssb, it does nothing to improve the signal to noise ratio. It does process the sound, and all functions of the program seem to work with my Samsung galaxy s 2 skyrocket, but it simply does not make faint signals any clearer or easier to understand. Admittedly, I have not used it for CW.
