Audio Speed & Pitch Changer — frequently asked questions
Is Audio Speed & Pitch Changer really free?
Yes. The speed and pitch modifier is 100% free with no registration, subscription fees, or audio length limits.
Can I change audio speed without altering the musical pitch?
Yes. When "Preserve Pitch" is enabled, our time-stretching algorithm speeds up or slows down playback (from 0.5× half-speed to 2.5× fast) while keeping the original musical pitch intact.
Can I transpose or pitch-shift audio tracks?
Yes. You can transpose your audio by up to ±12 semitones (one full musical octave up or down), making it ideal for vocal practice, karaoke tuning, and instrument rehearsal.
Does the tool support common audio formats like MP3 and WAV?
Yes. The tool accepts WAV, MP3, OGG, AAC, FLAC, M4A, and MP4 audio tracks, outputting clean, uncompressed WAV audio.
Is my audio file kept private?
Yes. Processing occurs on-device in your web browser. Your recordings, music tracks, and voice notes are never stored or logged on any external server.
