What’s a Pitch Changer or Shifter? How Does It Work?

A pitch changer or a pitch shifter is a tool that lets you change the pitch of any audio file without messing up the tempo. 

Here’s what you can use a pitch shifter for:

  • Singing karaoke in your own key
  • Speeding up music
  • Slowing down a fast melody
  • Creating harmonies by adding layers of your voice at different pitches for a fuller sound

How Does a Pitch Changer Work?

We all know that higher-pitch sounds have shorter, faster waves, while lower-pitch sounds have longer, slower waves. To raise the pitch, a music pitch changer shortens the waves by removing some parts. To lower the pitch, it lengthens the waves by adding in extra bits.

While stretching or shrinking the MP3 file to change its pitch, the pitch changer MP3 tries to make the transitions as smooth as possible. It does this by filling in any gaps or avoiding creating any weird robotic sounds.
