Audio Merger

Join multiple local audio files in a chosen order, add optional gaps or crossfades, and export one combined track.

Use the tool

Your audio stays on this device. Processing happens in your browser.

How it works

This tool uses browser audio features to process or inspect local sound. Results depend on the codecs and hardware available in your browser. Keep this tab open while processing.

Compatibility

For the most reliable results, use a current browser and WAV, MP3, AAC, Ogg, or FLAC audio it can decode. Exports use uncompressed WAV unless the tool provides an image or text sidecar.
