Audio Pitch Changer
Free online audio pitch shifter. Change pitch up or down by semitones without affecting speed or duration. Perfect for musicians, vocalists, and audio editors.
How does pitch shifting work?
Pitch shifting changes the frequency of audio by adjusting the sample rate, then resampling back to the original rate to maintain the same duration. This shifts the pitch without changing speed.
What is the difference between semitones and cents?
A semitone is the smallest interval in Western music (e.g., the distance between adjacent piano keys). A cent is 1/100th of a semitone, used for fine-tuning pitch adjustments.
