Semitones & Pitch Intervals
Convert pitch ratios to semitones and cents, and calculate frequency intervals.
Interval to Frequency Ratio
- Interval to Ratio: $Ratio = 2^((Semitones + Cents/100)/12)$
- 1 Octave always equates to a 2.0 ratio. A Perfect Fifth represents approx 1.498 ratio in equal temperament, and exactly 1.5 in pure Pythagorean tuning.
