About the Audio Joiner
Joining audio files is handy for making a continuous mix, combining parts of a recording that were saved separately, stitching voice notes together or building a podcast from segments.
Files in different formats and sample rates can be mixed freely; SoundBench converts them to a common format before joining. Everything happens on your device.
How to use the Audio Joiner
- Drop two or more audio files onto the joiner.
- Use the arrows to set the order, then choose a crossfade or a gap if you want one.
- Listen to the preview and click Export to download the joined file.
Frequently asked questions
How do I merge MP3 files into one?
Drop the MP3 files onto this page, arrange them in order and click Export with MP3 selected. The result is a single MP3 file.
What does crossfade do?
A crossfade fades the end of one track out while the next fades in, so songs blend smoothly like a DJ mix instead of stopping and starting.
Can I join files of different formats?
Yes. You can mix MP3, WAV, M4A, FLAC, OGG and others. They are converted to the sample rate of the first file before joining.
