Frequently Asked Questions
What is a semitone?
A semitone is the smallest musical interval in Western music. 12 semitones equal one octave. Our pitch shifter allows you to adjust pitch by ±12 semitones, giving you a full octave range in either direction.
Will pitch shifting affect audio quality?
There may be minimal quality loss when using pitch shifting, but our high-quality algorithms minimize artifacts. For best results, use lossless formats like WAV or FLAC as input, and choose appropriate quality settings for MP3 output.
Can I preserve the original tempo?
Yes! Enable 'Preserve Tempo' to keep the original speed while changing pitch. This is useful when you want to change the key of a song without making it faster or slower. When disabled, both pitch and tempo will change together.
What's the maximum pitch shift range?
You can shift pitch by ±12 semitones (one octave in either direction). +12 semitones raises the pitch by one octave, while -12 semitones lowers it by one octave. You can make precise adjustments in single semitone increments.
What audio formats are supported?
Input formats: MP3, WAV, FLAC, AAC, M4A, OGG, WMA, AIFF and more. Output formats: MP3, WAV, FLAC. For best quality, use lossless formats (WAV, FLAC) when possible, especially for professional applications.
Can I process multiple files at once?
Yes! Our tool supports batch processing. You can upload multiple audio files and apply the same pitch settings to all of them. Each file will be processed individually with your chosen settings.
Is this tool really free and private?
Yes, completely free with no hidden costs, subscriptions, or usage limits. All processing happens locally in your browser using WebAssembly. Your audio files never leave your device and are not uploaded to any server.
When should I use pitch shifting?
Common uses include: changing the key of a song for different vocal ranges, adapting music for instruments in different tunings, creating harmonies, correcting pitch in recordings, and creative audio effects in music production.
