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. Specifications: Available range: C2 - C6 Compatible with the following sampling rate (from 44.1khz to 96khz) System Requirements: AUv3 host (in case of using the app as AUv3 plugin)
