What does it mean to reverse audio?

Reversing audio flips a file front-to-back, so the last sample plays first and the first sample plays last - every note, word and drum hit runs in the opposite order. This tool decodes your file, reverses every audio channel, and lets you play back and download the result. It runs entirely in your browser: your file never uploads to a server.

How to reverse an audio file

Turning a track backwards takes three steps:

  1. Drop your file - drag it onto the upload area or click to browse. Up to 100 MB.
  2. Wait a few seconds - the tool decodes the audio and reverses it locally.
  3. Preview, pick a format, download - listen to the reversed result right on the page, choose MP3 or WAV, and save it.

Does reversing audio lose quality?

No. Reversing only reorders the samples that are already in the file - it doesn't remove, resample, or recompress anything. Download as WAV and the reversed audio is bit-for-bit as lossless as your source. Download as MP3 and you get the same quality tradeoffs as any MP3 export, unrelated to the reversal itself.

What formats can I reverse?

Input accepts WAV, MP3, M4A, FLAC, OGG, AAC and Opus files up to 100 MB. Output is MP3 at 128-320 kbps or uncompressed WAV.

Note: OGG and Opus input may not decode in Safari - use Chrome or Firefox for those formats.

Why reverse a track?

Reverse audio vs. other edits

Reversing is a full-file flip - different from trimming a section (use the MP3 cutter) or smoothing a transition with a fade in or out (use the audio fade tool). Combine all three for a full reversed-swell effect: cut the section you want, reverse it, then fade it in.

Frequently asked questions

How do I reverse an audio file?

Drop your audio file onto the tool. It decodes the file, flips every channel back-to-front, and plays back the reversed result instantly. Pick MP3 or WAV and download.

Does reversing audio lose quality?

No. Reversing just reorders the existing samples - it does not remove or recompress any audio data. Downloading as WAV keeps the result lossless; downloading as MP3 applies the same encoding tradeoffs as any MP3 export.

What formats can I reverse?

WAV, MP3, M4A, FLAC, OGG, AAC and Opus input. Output is MP3 (128-320 kbps) or WAV.

Is my audio uploaded to a server?

No. Decoding and reversing happen entirely in your browser using the Web Audio API. Your file never leaves your device.

What's the maximum file size?

100 MB per file.

Why would I reverse a track?

Reversed audio is a common production technique - reversed cymbal swells and vocal snippets are staple transition effects, and reversing a full track is also a quick way to check a mix for backmasked content or just for a novelty listen.
