The screenshots show some of the dynamic zooming capabilities, and the linear vs logarithmic modes. The first screenshot shows the analyser in linear mode, while the next shows logarithmic. The screenshots show the mic on the OG Droid phone capturing a test tone at 21kHz, in addition to other frequencies. Nice real-time analyzer!
The last two screenshots show a zoomed in signal at the lower frequency range - same signal sample (paused again), with two different windows applied.
I am honoured and humbled by each and every purchase made; thank you!

Fix for Toshiba Thrive, and Dell Streak mic input issue.
Fix for Samsung Captivate (Galaxy S SGH)! Thanks for the report Red Baron - if this update fixes your problem, I would appreciate an update to your review.
Contains workaround for the Atrix phone hardware microphone issue. UPDATE: Fix confirmed! Thank you Motorola engineering for the workaround.
My goal is to make a useful spectrum / spectral analyser tool for audio professionals, engineers, installers, etc. Signal processing is useful in many fields, from microphone analysis to RTA, to engineering / technical fields. Let me know how you use it! I find it fascinating the different uses.
Here are the permissions the app requests, and why:
* android.permission.RECORD_AUDIO To capture audio from the Microphone to display
* android.permission.WRITE_EXTERNAL_STORAGE Save the graph to an image, and send it via email.

Great Spectrum Analyzer and excellent support. Ability to capture/share plots is really handy.
★★★★★
Outstanding spectrum analyzer. Provides an accurate view of any sound wave captured by the phone's microphone. The display is easy to read and incorporates a lot of information essential in understanding the complexity of sound waves. It is an excellent tool for measurement and adjusting the acoustics of a home theater system. I am very pleased with it.
★★★★★
I love the app but would love to be able to use the 3.5mm jack on my phone as an audio input. If that could be added this app would be perfect.
★★★★★
Was great but now is broken. The settings menu is not accessible.
★★☆☆☆
Used to be the best analyzer on Android! Very sluggish, to the point of being unusable following an update in early 2016. The refresh rate seems to only update the graph twice a second. If you are looking at complex signals or using it in a live performance environment, it just isn't fat enough. At one point this was my absolute favorite analyzer on Android. Now it is worthless.
★★☆☆☆
NOT WORKING ANYMORE! No updates? Project dead? Update: Not working anymore :-(( Probably Android 6 that killed it. Old review: The app itself is very basic, but ok. But with the high resolution screen on Note 4, it's impossible to see the axis scales. Sadly, it has no calibration file support, so that not even the calibrated IMM-6 microphone can give accurate results. No updates for a couple of years? Not good - and very sad.
★★☆☆☆
Used to love this app then with an update it's all choppy. Very unhappy because this was my favorite spectrum analyzer app.
★★☆☆☆
It's great unless you have greater than kitkat. Lollipop and marshmallow: analyzation lags significantly. Under kitkat it was seamless. It's great unless you have kitkat. Lollipop and marshmallow: analyzation lags significantly. Under kitkat it was seamless.
★★☆☆☆
Slow because screen resolution to is set too high - unreadable db and freq values - developer ignoring mail queries , which is even worse , very disappointed , tested on new galaxy s6 edge , money wasted.
