Die Grundfrequenz des Tons in Hertz. Höhere Werte bedeuten einen höheren Ton.
Pitch MIDI Notes
0 - 127 (Im Sichtbereich: ca. 36 - 96)
Die Übersetzung der Frequenz in den standardisierten MIDI-Standard.
Jede Ganzzahl entspricht einer Taste auf einem Klavier (z. B. 60
= das eingestrichene C / C4).
Pitch Names
C-1 bis G8 (Im Sichtbereich: C2 bis C7)
Der traditionelle musikalische Notenname inklusive der Oktave
(z. B. "A4" für den Kammerton bei 440 Hz). Ein "#" steht für
ein Kreuz, ein "b" für ein Be-Vorzeichen.
Pitch Deviation (Cents)
-50 bis +50 Cents
Die Intonationsabweichung von der exakten Tonhöhe der Note.
100 Cents entsprechen einem Halbton. 0 bedeutet perfekt gestimmt;
positive Werte sind zu hoch, negative zu tief.
The fundamental frequency of the sound in Hertz (cycles per second). Higher values represent a higher musical pitch.
Pitch MIDI Notes
0 - 127 (In view range: approx. 36 - 96)
The conversion of the frequency into the standardized MIDI note numbers. Each integer represents a piano key (e.g., 60 = Middle C / C4).
Pitch Names
C-1 to G8 (In view range: C2 to C7)
The traditional musical note name and its octave (e.g., "A4" for the concert pitch at 440 Hz). "sharp" (#) or "flat" (b) indicate accidental pitches.
Pitch Deviation (Cents)
-50 to +50 Cents
The microtonal deviation from the perfect pitch of the detected note. 100 cents equal one semitone. 0 means perfectly in tune; positive is sharp, negative is flat.
Note for Batch Analysis:
Unlike standard mathematical offline analysis, the AI pitch model (CREPE)
requires real-time stream processing.
The tool will play through all files silently in the background.
The analysis will take exactly as long as the total audio duration.
