Description

SpecScope Spectrum Analyzer 2 is a frequency spectrum analyzer using a FFT to acquire a fast and accurate representation your surroundings. It can be used in many audio and engineering situations to attain a power vs frequency plot.

Features include :
- Advanced and simple touch gestures to scale the viewable area of the graph
- Save and recall previous signals from file
- Logarithmic or Linear frequency scales
- Selectable number of bins for accuracy versus speed
- Controllable averaging algorithm for response smoothing
- Peak hold signal with controllable timeout
- Hold off signal which only triggers when the previous maximum has been surpassed
- Tap to pause and resume measurements (graph is still navigational in this mode)
- Optional measurement markers for ease of reading

Poor resolution at low frequencies due to only having high sample rates. I need sample rates down to 8 kHz, preferably 4 kHz. No readout for peak frequency, particularly one that can can be held long enough to look at it after looking over at something else in the room. Somewhat of a pain to scroll/zoom. Wish there were a way to manually set axis limits and prevent accidental change upon touching the screen.

Great work!

Work in progress but still the best I'll start by saying that the original (free) version was/is the best spectrum analyser there is for Android if you want an engineering tool. This could be a blank screen and I'd have happily paid for it as thanks for the old one. However, at this stage it feels like a beta release (which it may be). The save profile feature is a massive improvement over a screenshot but it's not clear when it saves the waveform (capture button would be nice). I'd like to have windowing but can imagine it's not a priority

Much better Smoother than the old SpecScope. Get it.

Thanks for taking the time to give you suggestions. If you are interested in the peak detection, I would suggested using the peak hold feature and pausing the signal when it is present. You can then use the markers to attain the frequency and amplitude. I will review your other suggestions. Thank you

I've updated the app to 1.2.0, which has some of the features you required. If you would like to discuss any other features I would be happy to listen via nfxdevelopment@gmail.com.
