Questions fréquentes

Quick answers.

Will changing the pitch affect the tempo?

No. This tool uses time-stretching algorithms to ensure the duration and speed of the track remain identical while the pitch shifts.

What is a semitone?

A semitone is the smallest interval used in Western music, equal to one twelfth of an octave or one key on a piano. Shifting by 12 semitones moves the audio up or down exactly one octave.

Which file formats are supported?

The tool supports common web-standard audio formats including `MP3`, `WAV`, `OGG`, and `AAC`. The output is typically provided as a high-quality `WAV` or `MP3` file.

Is my audio privacy protected?

Yes. The pitch-shifting logic runs entirely via the Web Audio API in your browser, so your files stay on your computer throughout the process.
