Frequently asked questions
Is my audio uploaded to a server?
No — the Change Audio Speed processes audio locally using your browser's built-in audio APIs; files aren't sent anywhere.
Is there a maximum recording or file length?
No artificial cap is imposed by the tool itself; very long files simply take more processing time and browser memory.
Does the microphone recording require a permission prompt?
Yes — your browser will ask for microphone access the first time; this is a standard browser permission, not something the tool can bypass.
Does it work on mobile?
Yes, the Change Audio Speed works in mobile browsers as well as desktop.
