PitchChanger

Pitch Changer

Raise or lower the key of any song without changing its speed, then save it as MP3 or WAV.

Common key changes

Four settings people reach for most. Load one into the pitch changer, then open your song to hear it.

  • Too high to sing

    G major→F major

    • −2 semitones
    • Same speed and length

    Lower a whole step when the chorus strains your voice, and one more if it still feels high.

  • A male voice on a female song

    A major→E major

    • −5 semitones
    • Same speed and length

    Men singing a song by a woman often go down 3 to 5 semitones. Raise it for the reverse.

  • Play along in standard tuning

    E♭→E

    • +1 semitone
    • Same speed and length

    Many rock records are tuned half a step down. Raise the track one semitone and play along.

  • Practice slowly

    100 BPM→75 BPM

    • 0.75x speed
    • Same key
    • Length ×1.33

    Learn a hard passage slowly while the song stays in its original key.

How to change the pitch of a song

Three steps, all on this page.

  1. Open your song

    Choose or drop an MP3, WAV, M4A, FLAC or OGG file, or a video. Its key and BPM show up on their own.

  2. Set pitch and speed

    Drag Pitch while the song plays. Turn on Semitones for whole steps and watch the new key appear.

  3. Save the new version

    Pick MP3 or WAV and press Save. The saved file keeps your song’s name.

Why use this pitch changer

A key changer that keeps everything else about your song intact.

  • Tempo and length stay put

    Changing the pitch leaves the speed alone. A 3:30 song is still 3:30 in its new key.

  • Key and BPM detected

    See the original key and tempo next to what they become as you move the sliders.

  • Processed on your device

    Your song is opened, changed and saved in your browser. It is never uploaded.

  • MP3 320 kbps or WAV

    Save at the sample rate of your file, as a small MP3 or a full quality WAV.

  • Works with video files

    Open an MP4, MOV or WebM and get its soundtrack back in the new key.

  • Free, no sign-up

    Every feature is free. Open the page and start, with no account to create.

How many semitones to transpose

Each semitone moves every note by one piano key. Find the key change you want, then check it by ear.

Counting semitones

  • Count every key from one note to the next, black keys included.
  • Twelve semitones make an octave, so 6 up or 6 down reaches every key.
  • Lower is minus, higher is plus: G major to F major is −2.
  • A capo on fret 2 raises open chords 2 semitones. Lower the track by 2 to play the same shapes without it.
Semitone shifts and the keys they lead to, starting from C major

Who uses a pitch changer

Anyone who needs a song in a different key or at a practice tempo.

  • Singers and karaoke

    Move a song or backing track into a key that fits your voice, then take the MP3 to rehearsal or karaoke night.

  • Instrument practice and transcription

    Match a recording to your tuning or capo, slow tricky parts to 0.75x, or fine-tune an older recording in hundredths.

  • Video creators

    Shift music a semitone or two to sit under a voice-over. At 1.00x the length stays the same, so your edit stays in sync.
