Description from Developer

Editor Review

You are Downloading Speedy Spectrum Analyzer Latest APK 3.06. Last Updated: Nov 23, 2016.

Speedy Spectrum Analyzer developed by Electron Chaos is listed under category Music & Audio 4.5/5 average rating on Google Play by 1556 users).

Speedy Spectrum Analyzer's main feature is Audio FFT / Spectrum Analyzer from your devices internal or external microphones.

Speedy Spectrum Analyzer apk was fetched from play store which means it is unmodified and original.

* Peak Hold Overlay option * Peak Hold long-press enable * 48 kHz audio sample rate option (device dependent; will fall back to 44.1kHz if your device does not support 48kHz) * Select between 'Default' and 'Front' mic (device dependent) * Fix for Toshiba Thrive & Dell Streak mic issue


It's a real-time audio spectrum analyzer.

Leaps above the previous app I was using.

I have been playing with this app for a few days.

Software is easy to use and it runs very smoothly on my SGS2.

I wish more apps were this well done.

I used it to capture a troublesome harmonic on a servo motor.

Great tool for analyzing audio.

Best RTA on the market for sound reinforcement.

I use it in my work as a live audio engineer.

Useful - especially when tracking down high pitch whines / noises.

Regular updates and enhancements from dev.

The developer really listens to your input and the new update.

Fast Update and Accurate.

This one is made for professionals.

This tool helped me adjust crossover frequencies and levels precicely.

Best of breed.

Clear and simple.

I bought this based on prior reviews.


Since i am looking for an intermittent noise issue.

9khz Android background noise issue.

Wish there was a desktop version fot mac or pc.

Although it would be nice to have an SPL meter.

needs larger fonts and manual for 5 star rating.

Doesn't justify cost.

Needs more tutorial or help guides.

No response from dev to email.

but otherwise a very useful tool.

but shows fine on email capture.

I see nothing in Settings that allows enlarging it.

Ability to access menus or set preferences disappeared.

Could be awesome if you could use an external mic via usb.

positively needs a logarithmic frequency scale.

Being forced to rate this before I am ready.

A couple tweaks would make even better.

If it had a white and pink noise generator it would be.

Can't be a protool without response and level.

would be nice if an external Mic could be selected.

Can't wait to be able to calibrate the SPL read out.

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!
