Order is explicit
Add files in the order you want to hear them and review the list before rendering.

Audio merger facts at a glance
A focused joiner for assembling source clips, not a multitrack DAW or a lossy online converter.
- Input
- Two or more browser-decodable audio files
- Edit
- File order and up to 5 seconds of crossfade
- Output
- One locally rendered 16-bit WAV file
- Privacy

Join clips without a server round trip
The first version keeps the core merge path small and inspectable.
Crossfade when needed
Use a short overlap to soften a hard transition between two adjacent clips.
Predictable WAV output
The merged result is a standard uncompressed WAV for another editor or video project.
How to merge audio files
Add the sources, check the sequence, then render one local artifact.
- 01
Add two or more files
Choose the audio clips you want to combine. Common browser-supported formats can be decoded locally.
- 02
Set the transition
Leave crossfade at zero for a hard join or add a short overlap for a smoother handoff.
- 03
Merge and download
Render the sequence in the browser and download the resulting WAV file for the next production step.
Where an audio merger helps
A simple sequence tool is useful when opening a full editor would slow down a small task.
Podcast segments
Assemble an intro, interview segment, and outro into one working file.
Music sketches
Put demos, hooks, or arrangement ideas into one reference for review.
Video handoff
Combine short music and voice assets before importing them into a video timeline.
Check the source sequence before export
A merge changes the container and timeline, so a quick review prevents avoidable rework.
Match the intended order
The list order is the final playback order. Add files again if you need a different sequence.
Keep crossfades short
A long overlap can hide transients or remove the end of a clip from the final timeline.
Listen to the WAV
Check the transition and level in the destination editor because the tool does not master the combined mix.
