Free Online Audio Pitch Shifter

Audio pitch shifting is the process of changing the pitch of an audio file without affecting its tempo or duration. This allows you to raise or lower the musical key of a song, making it higher or lower while maintaining the same playback speed.

Our free audio pitch shifter supports the most common audio formats including MP3, WAV, OGG, and M4A files. You can upload files up to 50MB in size for processing.

You can adjust the pitch by up to 12 semitones (one full octave) in either direction. This means you can raise the pitch by +12 semitones or lower it by -12 semitones, giving you a full two-octave range of adjustment.

Processing time depends on the length and size of your audio file. Most files are processed within 30-60 seconds. Larger files may take a bit longer, but you will see a progress indicator while your audio is being processed.

Pitch-shifted audio is perfect for creating karaoke tracks in different keys, matching vocals to instrumental backing tracks, music production and remixing, voice modification for creative projects, and making songs easier to sing for different vocal ranges.

Our advanced pitch shifting algorithm preserves audio quality as much as possible. The output is provided in high-quality WAV format. Small pitch adjustments (±3 semitones) typically have minimal quality impact, while larger shifts may introduce slight artifacts.
