Use the two players to compare your original recording with the processed version. Only one plays at a time. After changing a setting, process again to update the preview and download. Reset removes the file and restores the Slowed preset.
WAV downloads are larger. MP3 is compressed and leaves extra room for loud peaks, so it may sound quieter and add a little silence at the edges. Both use 44.1 kHz audio. Processing needs available memory and may take longer on a phone. Keep this page open and visible until it finishes; files are not saved between visits.
Use audio you own or have permission to edit. This tool changes playback speed and reverb; it does not generate a new song or identify BPM or key.
