About this app

mr spectra is an fft based audio spectrum analyzer with built-in weighting filters (A-weighting for human hearing, C-weighting for machine sounds and Z-weighting with no filter).

Enjoy mr spectra with your music as a musical mood light.

Quick tips:
* Go to settings and add a decibel, wave or spectrogram scope.
* Swipe screen to zoom in or out on frequency and amplitude scales.
* Display or hide the X and Y axes. Show or hide the dB and Max dB values.
* Reset Max dB.
* Move the dB and Max dB values anywhere on the screen by dragging.
* Pause/ Play the running spectrum.
* Hide menu and play/pause buttons.
* Change spectrum color scheme from the app menu.

Display Settings:
* Select color scheme.
* Solid bars or line graphs.
* Landscape mode to mirror screen on to your TV.
* Show/ hide axes.

Scope Settings:
* Decibel Scope.
* Sound Wave Scope.
* Spectrogram.

Decibel Settings:
* Use A-Weighting, C-Weighting or Z-Weighting filters (dBA, dBC, dBZ).
* Show decibel and Max dB values.
* Set zero dB level.

FFT Options:
* Use Hann or rectangular windowing.

Technical Details:
* Input source: device mic.
* Sound captured: 16-bit PCM mono.
* Sampling rate: 44.1 kHz.
* Audio amplitude range: 1 to 32767.
* FFT latency: 23 ms.
* Decibel calculations: based on rms amplitude, relative to a base level of 1 rms. The base level can be adjusted by user to calibrate dB levels.

Ratings and reviews

Really like this one! Simple to use but not dumbed down. Has more settings than most analyzer apps and option to display ONLY the spectrum with black background. My search is over. There is no other app available that even comes close. Absolutely Perfect!!! Thank you!

limited frequency range: only goes up to 4000Hz, and you can't adjust it. frequency range is also locked to a linear scale when it always makes more sense to display frequency logarithmically.

Sensitive & accurate, but too much lag and mic only input...also needs a full spectrum option (20 - 20Khz without swiping to see it all.)
