Question 1

How do I reverse an audio file?

Accepted Answer

Drop or upload an audio file (MP3, WAV, OGG, M4A, FLAC), then click Reverse. The reversed audio appears with a built-in player and a Download WAV button.

Question 2

What audio formats are supported?

Accepted Answer

Any format your browser can decode through the Web Audio API, typically MP3, WAV, OGG/Vorbis, M4A/AAC and FLAC. The reversed output is always high-quality 16-bit WAV.

Question 3

Is my audio uploaded to a server?

Accepted Answer

No. Decoding, reversing and encoding all happen locally in your browser. Your audio never leaves your device.

Question 4

Why is the output WAV instead of MP3?

Accepted Answer

WAV encoding is lossless and built into the browser, preserving full quality with zero dependencies. WAV files are larger but bit-perfect. You can re-encode to MP3 with any converter if needed.
