How to Use This Calculator
  1. Enter Original Frequency, Pitch Shift, and Original BPM.
  2. Set Link Pitch and Tempo.
  3. Review New Frequency (Hz) and Resulting BPM.
  4. Use Frequency Ratio and Cents Change (cents) to inform your decision.

What each input means

Original Frequency
The original frequency of the note or sound in Hz. A4 = 440 Hz.
Pitch Shift
Number of semitones to shift. Positive = up, negative = down. 12 semitones = 1 octave.
Original BPM
The original tempo of the track in beats per minute.
Link Pitch and Tempo
When enabled, tempo changes with pitch (like speeding up vinyl). When disabled, tempo stays constant (modern time-stretching).

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Original Frequency = 440, Pitch Shift = 7, Original BPM = 120, Link Pitch and Tempo = 0 = 4 input(s) provided
  2. Calculate New Frequency
    New Frequency
    659.26 = 659.26
  3. Calculate Resulting BPM
    Resulting BPM
    120 = 120
  4. Calculate Frequency Ratio
    Frequency Ratio
    1.4983 = 1.4983
  5. Calculate Cents Change
    Cents Change
    700 = 700
