Output quality and format
Reversal rearranges decoded samples. Output is 16-bit PCM WAV, without another lossy MP3 encode. Decoding may resample, and 16-bit export quantizes samples. This is not a bit-exact copy of the source and cannot restore lost detail.

Choose audio from Files or Downloads. Preview the result, then download WAV. Your browser may save directly to its downloads list; on iPhone open the download and save it to Files. Keep the page in front while processing. Longer recordings need more memory.
Audio reverser questions
Can I reverse just part of an audio file?
Yes. Choose Selected region, drag the handles or enter start and end times, then create and compare previews. The downloaded WAV contains only that reversed clip, not the surrounding recording.
Can I play audio backwards on my phone?
Choose a local file in your mobile browser. MP3 and WAV are recommended. Keep this tab in front while processing, preview the result, then save the WAV from your browser downloads.
Does reversing an MP3 also export MP3?
No. This tool decodes supported audio, including MP3, and exports 16-bit PCM WAV. MP3 export is not offered. The source stays unchanged, and the WAV will usually be larger than a compressed file.
