    1. Choose two or more audio files.
    2. Reorder them and set a crossfade or gap.
    3. Press “Join audio” and download the merged file.

    Questions people ask

    Can I mix different formats?

    Yes. MP3, WAV, M4A and OGG files can be joined together. They are converted to one sample rate and saved as a single file.

    How does crossfade work?

    The end of each file fades out while the next fades in over the time you set. The total length gets shorter by the crossfade time at each join.

    Is there a limit on files?

    No fixed limit. All audio is held in memory, so about one hour in total works well on most devices.
