How it helps

Use reverse audio on the go

Reverse audio is useful for creative sound effects, transitions, audio experiments, and checking how clips sound when played backwards.

The tool reverses the decoded PCM samples locally, then exports a downloadable MP3 or WAV output.

Processing runs in your browser after the file is decoded. Browser support depends on the file format, codec, device memory, CPU, and current browser features. For sensitive or confidential audio, review privacy practices carefully before using any online tool.

How to use

How to use this tool

Open the tool page. Choose the audio tool you need from the tools menu or related tools section.
Add your audio. Upload a supported audio file, choose multiple files for the joiner, or record from your microphone on the voice recorder page.
Adjust settings. Use the simple controls for fade, speed, normalization, silence removal, or compression.
Preview first. Listen to the processed preview before creating the final output.
Download manually. Create the output file, then click Download yourself. The page does not auto-download files.

Formats

Browser-supported audio input

The upload field accepts common audio extensions, but the browser must be able to decode the actual file. MP3 and WAV are the safest choices. OGG, OPUS, M4A, AAC, M4R, FLAC, and AIFF vary by browser and operating system.
