Pitch Analyzer APPLICATION description
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
