MUIC & ACOUTIC – AUDIO IGNAL PROCEING & DP CALCULATOR
Pitch Shift Semitones
A precise tool.
What is the Pitch Shift Semitones & How does it work?
The pitch shift is a process used in audio signal processing to change the pitch of an audio signal without affecting its duration. This is often achieved by altering the frequency of the sound waves.
A semitone is a unit of musical interval, equal to one-twelfth of an octave. In terms of frequency, each semitone represents a 12th root of two ((2^{1/12})) ratio increase or decrease in pitch.
f’ = f times 2^{n/12}
f’ = new frequency, f = original frequency, n = number of semitones

Frequently Asked Questions
How do I calculate the new frequency after a pitch shift?
Use the formula f’ = f imes 2^{n/12}, where f is the original frequency and n is the number of semitones.
What does one semitone represent in terms of frequency?
One semitone represents a 12th root of two ratio increase or decrease in pitch.
Can you explain how to use this calculator for a pitch shift?
Input the original frequency and the number of semitones to shift, then calculate the new frequency.
What is the difference between a semitone and an octave?
An octave is 12 semitones. Each semitone is one-twelfth of an octave.
How does pitch shifting affect audio duration?
Pitch shifting does not affect the duration of the audio; it only changes the pitch.
Can this calculator handle negative semitones for lowering pitch?
Yes, you can use negative values for n to lower the pitch.
What is the formula used in this calculator?
The formula used is f’ = f imes 2^{n/12}, where f’ is the new frequency, f is the original frequency, and n is the number of semitones.
