It's not bad but it needs a few additions to make it usable; Add a peak hold, or at least a stop so you can see what as going on. The display jitters so much that you cannot read frequencies being displayed - there just isn't time. Add an averaging function. This will also allow a human to read it. Allow larger fonts!
Brilliant spectrum analyser. The waterfall display reveals so much about the audio with harmonic distortion being plain to see on frequency sweeps. It would be great if this data could be output as a CSV file.
Very neat, well designed and implemented app. The zoom features work exactly as I'd expect, and the settings give me a lot of control over how audio is captured and analyzed. Surprised and delighted at the quality!
Great app with a few musing missing features like recording lengths of audio input, exporting the spectrum as... a picture maybe, pausing the flow, a switch to the internal audio. Then this would be a 6 star review.
Awesome! The most fully featured, performant android app for spectrum analysis I've yet used yet😎 And I've tried a ton.. In contrast to what another review said, this does have a lot of customisation. Includes features like: - peak hold - smoothing jitters (trade-off for responsiveness) - tweaking the detection algorithm (bins, method, etc) I challenge anyone to find a better app than this!
Very good and responsive spectrum analyzer. A useful missing feature would be to have an option to display musical note name along with the frequency.
- Added DC subtraction to remove bad readings around 0 Hz.
- Fixed a few small bugs.
