Concept:

The app “vocalScriba” will transcribe incoming singing intonations to visual pitch graph in real-time. It works as standalone or AUv3 plugin.

Usage:

There are eight 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).
8. Time Response: it has better time response with larger value.
9. Draw mode: determines whether the curve is smoothed or not. (Default: no)

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

Notes:

The app is made exclusively for vocal or monophonic instruments.
