Spectrum Analyzer

Description from store
Speccy is a simple spectrum analyzer app. It's designed specifically for use in Amateur (Ham) Radio, where signals such as Morse Code are found at lower audio frequencies. Therefore, Speccy should display data between zero and around 6 kHz, which is actually still quite useful for other things, such as looking at the audio frequencies in your voice.
The top part of the app window shows the audio spectrum, and the bottom half shows those data over time in a waterfall graph. I wrote it as I use my Chromebook for listening to, and decoding, software defined radio outputs, so it's good to be able to see what the main frequencies are.
Also, if like me you use a variable bandpass filter when decoding signals (I use a SotaBeams module), then this app is very useful for seeing the effects of the filter and tuning the center frequency.

- (2020-03-04) Peter Czerwinski: Useful App. Just run the app, and it displays an audio spectrum (0 - 6 kHz), in a small window. When you're done, close the window. Simple.
- (2019-12-11) Eric Crawford: not the speccy I expected
- (2019-08-22) Andreas Reischle: Very basic audio spectrum analyzer. Handy to have around as a radio enthusiast and ham radio operator.
- (2018-03-14) Mr. Spies: No direction on how to use. No home button.
