đ Understanding Pitch Detection
What is Pitch? Pitch is how high or low a sound is, measured in Hertz (Hz). Each musical note corresponds to a specific frequency.
Musical Note Scale:
- C4 (Middle C): 261.63 Hz - Reference note on piano
- A4: 440 Hz - Standard tuning reference
- C5: 523.25 Hz - One octave above Middle C
- Octaves: Each octave doubles the frequency
- Semitones: 12 semitones = 1 octave
Tuning Accuracy:
- In Tune: Within Âą5 cents
- Slightly Off: 5-20 cents sharp or flat
- Out of Tune: Beyond 20 cents deviation
- Cents: 100 cents = 1 semitone
Perfect for:
- Tuning instruments (guitar, violin, etc.)
- Vocal training (checking pitch accuracy)
- Music ear training (note recognition)
- Music transcription (identifying notes from audio)
- Audio analysis (frequency content)
