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 seven 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).
6. Input: input gain in dB.
7. Tuning: adjusts A4’s reference frequency in the range from 414hz to 467hz (default: 440).

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 44.1khz to 96khz)
