What this tool does
Reverses an audio file so it starts at its end and finishes at its beginning.

A practical example
Input
A ten-second audio clip.
Output
The same clip entirely reversed, its end now its beginning.
Limitations
- Reversed speech is inherently unintelligible.
- Reversing requires the whole file in memory, so long files are heavy.
- Only the whole file can be reversed, not a section.
Privacy and processing
Every sample is read and rewritten on your device; the file never leaves it.
Technical notes
- Reversing means reading every sample before writing them back in the opposite order.
