About Frequency Spectrum
This is a free frequency spectrum that I have developed for my music app. I used it to test on my keyboard and get very accurate reading. Place your finger on the spectrum to get the respective frequency. It has an accuracy of +/- 5 Hz.
It has an auto peak detection on the graph in red dot and the maximum frequency value to top right.
To be release musical app that uses this spectrum is
1. Power spectrum with Cepstrum to find fundamental frequency. https://play.google.com/store/apps/details?id=com.appspot.harmoncepstrum release on 040215
2. Piano spectrum. Published under app name Polyphonic Pitch Detector.

Problem: Ads cover up the frequency readout, rendering this app useless. I reported the ads as "Ad covers the page", but only time will tell whether this gets fixed. If we can't read the frequency, then this app is pointless because there is no logarithmic grid by which to see what the "center frequency" is.

LG Gvista 2/LG G stylo, Ad covers exact middle of readout. No scale showing frequency on bottom of screen like in dev screenshot. Goes to negative 80 decibels, why? Impossible. Waste of space where ad could of been. No options? At all? Not useful in the least in it's current state.
