Audio Pitch Shifter
Shift the pitch and change the speed of any audio file directly in your browser. The giga.tools audio pitch shifter lets you transpose audio up or down in semitones and adjust playback speed - all without uploading your file to a server. Everything runs locally and privately.
How do I shift the pitch of an audio file online?
Upload your audio file to the giga.tools pitch shifter, adjust the pitch slider to transpose your audio in semitones (up to 12 semitones in either direction), and optionally change the speed. Click download to save the result as a WAV or MP3 file. The entire process happens in your browser with no sign-up required.
What is audio pitch shifting?
Pitch shifting is the process of raising or lowering the perceived pitch of an audio signal without changing its fundamental character. One semitone corresponds to the smallest interval in Western music - twelve semitones make up one octave. Shifting pitch up by 12 semitones doubles the frequency, while shifting down by 12 semitones halves it. This is useful for transposing songs to a different key, adjusting vocal recordings, or creating creative audio effects.
How does speed adjustment affect audio?
Changing the playback speed of audio makes it play faster or slower. At higher speeds the audio sounds higher in pitch, and at lower speeds it sounds lower in pitch. The speed slider on this tool lets you set a multiplier from 0.25x to 4.0x, giving you fine-grained control over how fast or slow the output plays. Combined with the pitch slider, you can achieve a wide range of audio transformations.
What audio file formats are supported?
The pitch shifter accepts all common audio formats including MP3, WAV, OGG, FLAC, and AAC. You can also upload video files - the tool will automatically extract and process the audio track. Output can be downloaded as WAV (lossless, default) or MP3 (compressed, smaller file size) using the download dropdown.
Is my audio data private?
Absolutely. All audio processing happens entirely in your browser using client-side technology. Your audio files are never uploaded to any server. Once you close the tab, the processed data is gone. If you're working with sensitive audio like voice memos or unreleased music, your files remain completely private. For other audio editing needs, check out the audio volume changer or the reverse audio tool.
