Frequently Asked Questions
How do I speed up an audio file?
Upload your audio and choose a speed above 1x — 1.5x or 2x are popular for podcasts and lectures. Preview the result and export when it sounds right.
Can I slow down music to practice along with it?
Yes. Choose a speed below 1x, such as 0.75x or 0.5x, to slow a song down so you can hear every note while you practice.
Does changing speed distort the sound?
Moderate speed changes stay clear and natural. Extreme settings will naturally sound more processed, so preview before exporting.
Is the audio speed changer free?
Yes, completely free with no registration required, for files up to 500MB.
