ADVERT
Audio Joiner
Join multiple audio files into one merged MP3 or WAV output in your browser. Upload tracks, reorder externally, and export quickly.
How to use this tool
- Upload two or more audio files in the order you want merged.
- Select output format and adjust MP3 bitrate if required.
- Merge tracks, preview the joined output, and download the final file.
Typical workflows
- Combine podcast segments into one final delivery file.
- Join chapter recordings for handoff or review playback.
- Merge short voice clips into a single timeline export.
Before merging
- Normalize loudness in source files to reduce level jumps.
- Double-check file order since concatenation follows list sequence.
- Choose WAV for archival quality and MP3 for lightweight distribution.
FAQ
- Can I add crossfades between tracks?
- Not currently. This tool concatenates files directly without transition effects.
- Do sample rates need to match?
- No. Source buffers are resampled as needed so they can be merged.
- Is merging done in-browser?
- Yes. Decoding and merge operations run locally in your browser.
