Control track order
Arrange clips before export because the displayed sequence becomes the playback sequence in the joined file.

Audio Joiner
Arrange and combine browser-decodable audio tracks into one WAV file.
Ordered WAV merge
Audio Joiner
Media is decoded, transformed, and encoded locally. Nothing is uploaded to any server.
Add audio files to set their join order.
The practical guide
Join audio in a chosen order with a common output format.
Each source is decoded, converted to a compatible channel and sample-rate representation, then placed sequentially in a new WAV buffer.
Decode and normalize
Different source codecs, channels, or sample rates must be decoded and normalized before their samples can be combined.
WAV output and gaps
The result is an uncompressed WAV with clips placed back to back. It does not add crossfades, mixing, or compressed MP3 output.
Privacy by architecture
Your sensitive tool inputs stay on your device.
Tool inputs, settings, and outputs are processed locally and are not intentionally sent to an application server.
Questions, answered
Frequently asked questions
Which output format is created?
The joined file is exported as WAV.
Can files use different formats?
Yes when the browser can decode each source; unsupported codecs will be rejected.
Does joining normalize loudness?
No. Technical sample-rate and channel conversion does not guarantee equal perceived loudness.
Can tracks overlap or crossfade?
No. This joiner places tracks sequentially without mixing or transition effects.
