DSP Audio Filter for Android
Hi, Had to reinstall after Marshmallow upgrade. Thanks. God bless. Aaron
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.
Any chance for a refund? This isn't the tool I was looking for.
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.
Used it to try a cancel a buzzing noise on a specific frequency, works great.
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.
This is great app. During our induction motor testing I could filter bearing noise from electrical noise. Well. You have such a large scale. If you could zoom into couple khz instead of 20k, we could identify each sound on scale. But again, this is great app for my HTC vivid. Please improve this app.
I will experiment to see if the filter can have positive results with Tinnitus. Mine occurs 24/7 around 5800 Hz sometimes bearable otherwise unbearable!
I find this app very useful in listening to my beehives to find out about their health. Very nice functionality. The developer responds quickly and effectively if there are any questions.
This app is NOT compatible with my Archos 43it. Locks up each time I start it.
This is the tool I wish I had when I was stuck on a ten hour flight with a whine in the audio system. Note: to apply this tool, having a background in frequency analysis helps.
Does not work on Android Samsung Galaxy.
All this is, is a software based variable Bandpass/Notch filter which is great for filtering out QRM on the edges of the signal you're trying to hear, but does nothing for QRN. If it does I haven't heard a noticeable difference. Still this can cut out a lot of the noise which makes it useful for older radios that lack any kind of filtering. Currently doesn't work correctly on my EVO Shift, but works great on my old G1. 4 stars if it starts working right on the Shift or adds QRN filtering. 5 for both.
LG Optimus 2X dual core phones are powerful but audio quality sucks. you have great potential to develop a good filter to control sensitive microphone
Sory,i dont hear nobody from headset! ZTE V9 Android 2.1 skakai4@ gmail com

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
