AudioTool runs entirely in your browser. When you open a tool and choose a file, the audio is processed on your own device, so nothing is sent to a server and nothing is stored.

Use the tools to trim a song into a ringtone, join voice clips, make quiet recordings louder, change the speed or pitch of a track, convert between formats, or pull the audio out of a video.
