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

Quick tips:
* Show or hide the dB and Max dB values.
* Go to settings and add the Strobe Lights, or a decibel, wave, or spectrogram scope.

Display Settings:
* Select color schemes.
* Solid bars or line graphs.

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

Strobe Lights Settings:
* 3 lights (Bass, Mid, Treble) or 4 lights (Bass, Mid, Treble, High Treble).
* Full screen mode.

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

Ratings and reviews

This app has added more impressive performance by adding audio internal aside from mic source thank you for your understanding God bless you and your family 🎁

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.
