Pitch Shift Without Tempo Change

Traditional speed playback changes both tempo and pitch simultaneously. Pitch shifting without tempo change only alters the frequency (pitch) while keeping the original duration and rhythm intact β€” for example, making a voice sound higher without talking faster.

πŸ“– Frequently Asked Questions

What does 'pitch shift without tempo change' mean?

Traditional speed playback changes both pitch and speed together (like a tape being sped up). Pitch shifting without tempo change only alters the frequency (pitch) while keeping the original duration and rhythm. For example, shifting a male voice to sound female while maintaining normal speech rate. This tool uses the Web Audio API for processing.

What audio formats are supported?

All major audio formats are supported: MP3, WAV, OGG, AAC, M4A, FLAC, WEBM, and any format your browser can play. Output format defaults to WAV (lossless), with OGG as an alternative (lossy but smaller file size).

Will my audio be uploaded to a server?

No. All audio processing is done locally in your browser using the Web Audio API. Audio data never leaves your device, ensuring complete privacy.

What is the pitch shift range?

This tool supports -12 to +12 semitones (one octave range), with each semitone divided into 100 cents for fine adjustments, totaling -1200 to +1200 cents. You can also directly input the semitone value for precise control.

Why does the processed audio have artifacts or distortion?

Large pitch shifts (more than Β±6 semitones) may cause audio quality degradation or noticeable artifacts ('chipmunk effect'). This is a limitation of the phase vocoder algorithm. For best quality, keep pitch shifts within Β±4 semitones. For larger shifts, consider adjusting in multiple smaller steps.
