pitchGraf

Concept:

The app is a pitch monitoring tool and works as standalone or AUv3 plugin. It will analyze an incoming audio signal using FFT and display its spectral graph in real-time (unit: musical pitch not hertz). The user can watch and study in detail the pitch distribution of audio source.

Usage:

There are five sliders.

1. Resolution: determines the analysis resolution. (higher resolution - worse time response) vice versa
2. Pan: works as panner, only if input source is stereo.
3. Magnify: magnifies the screen horizontally.
4. Slide: slides the screen horizontally.
5. Out: determines the audio output to be turned on or off (default: Off).

In the app the pitches are represented as follows:

C -> C
Cis -> 1
D -> D
Es -> 3
E -> E
F -> F
Fis -> 6
G -> G
As -> 8
A -> A
B -> B
H -> H


Specifications:

Compatible with the following sampling rate (from 44.1kz to 96khz)
