Each sound is played backwards, from its end to its start.
Each sound is changed whole in your browser's memory, up to 20 minutes long. MP3, M4A and OGG are written at 192, 192 and 128 kbps; WAV and FLAC lose nothing. WMA and AIFF aren't read.
How to reverse an audio file
- Drop your sound files on the page or choose them; videos give their sound.
- Pick the format to save as.
- Each file is reversed as soon as it's added; download it, or all of them in a ZIP.
