How It Works

1Select an audio file by clicking the upload zone or dragging and dropping it, or switch to the "Record Audio" tab to capture audio from your microphone.
2Wait a moment while the audio is decoded and reversed entirely in your browser — your file is never sent to a server.
3Use the Original and Reversed players to compare both versions side by side. Adjust the playback speed or seek through the audio.
4Click "Download Reversed WAV" to save the result as a lossless 32-bit float PCM WAV file.

Encode and decode Base64 strings

Inspect and edit binary files in your browser with hex view, decoded text, and a data interpreter panel

Select a precise start and end point in any audio file or recording and download the cut segment as WAV — fully in-browser, no uploads.
