vocalScriba (AUv3 plugin)

 Concept:


The app “vocalScriba” will transcribe incoming singing intonations to visual pitch graph.

Usage:


There are six sliders & one button.

1. Clear: clears the drawn graph.
2. Thresh: means input threshold, in other words input sensitivity.
3. Magnify: magnifies the screen horizontally.
4. Slide: slides the screen horizontally.
5. Out: determines whether the audio output to be turned on or off (default: Off).
6. “Voiciness”: it becomes less responsive to consonants with higher value.
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
