About Pitch Analyzer
A pitch is detected by analyzing input sound and displayed in real time.
This app can help you to tune a musical instruments or practice a singing.
--------------------------------------------------------------------------------------------------------
A pitch detection was an octave off until ver 2.0.0 ( A4 was displayed at A3 )
I corrected the bug in ver 2.0.1
I am terribly sorry to have troubled you so much.
--------------------------------------------------------------------------------------------------------
On the graph area:
* Move a scale display area by dragging
* Zoom in and out by pinching (or push the buttons on the bottom of the graph)
Display area of a volume graph and pitch detection sensitivity is adjustable using the bars
on the bottom of the screen.
Purchase this app:
* Release function restrictions on a setting screen
* Remove ads
Setting items:
* Graph [Log, Liner]
* Scale [Equal temperament, Frequency [Hz]]
*Window function [None, Hanning window]
(Window function can improve accuracy of a pitch detection, but you would hardly feel the difference)
Technical info:
* A pitch is calculated by a autocorrelation function (using FFT, IFFT, for fast computation)
* Sampling frequency is 8000 Hz
* The frequency at A4 is 440 Hz

Will not recognize A0. Indicates an A2 when a Bb0 is produced. Indicates D4 when a D5 is produced, etc. Galaxy S4.

Thanks to the Dev, who listened to my comments! The app's coming along nicely. My next suggestion would to simplify using this as a tuning tool :-)

This app works nice with instruments and voice, more of a toy or curiosity at this stage, it seems the app is in active development, I paid to support the author. Some more effort needed but this is the only app of it's kind I've found on market to date, and this kind of analysis ain't easy, so we should encourage further updates! My first suggestions would be label up the sliders, current pitch display, ave. mean pitch display etc. :-)
