    WAV output settings

    Add at least two clips. Blank sample rate uses the first clip's rate. Keep input channels requires every clip to have the same channel count; choose Mono or Stereo to normalize mixed clips. Export is 16-bit PCM WAV with hard cuts between clips, without fades or silence removal.

    Preparing the tool…

    Before you start

    Join at least two WAV or browser-decodable MP3 clips into one continuous PCM WAV. Preview a source, move clips up or down, and check the exact join order before downloading. Processing stays in this browser.

    How to use this tool

    1. Add at least two local WAV or MP3 clips. Listen to any source and use the arrows to set top-to-bottom playback order.
    2. Leave sample rate blank to use the first clip's rate. For clips with different channel counts, choose Mono or Stereo before merging.
    3. Check the joined time ranges, listen to the merged WAV, then download it.

    Supported inputs and limits

    2–20 WAV or browser-decodable MP3 clips; 30 MiB input in total and 80 MiB decoded source samples. PCM16 WAV output; 8–192 kHz and up to 8 input channels. Clips join at hard cuts without fades.

    Worked example

    Example input

    tone.wav
tone.wav
    Example options
    {}

    Example output

    merged.wav — 4 seconds, 48,000 Hz, mono, 16-bit PCM

    When something does not work

    Use at least two supported clips within the file and decoded-memory limits. If channel counts differ, select Mono or Stereo. The output is PCM WAV rather than MP3; listen around each join and check clipping warnings.

    Frequently asked questions

    Are my files uploaded?

    No. Files and tool input are processed in your browser. Moving around the site can keep a temporary workspace in the same tab. Refreshing or closing the tab clears it, so download results you want to keep.

    Will this preserve MP3 quality or add fades?

    Output is 16-bit PCM WAV. Decoding MP3 cannot restore quality already lost. Downsampling attenuates frequencies above the new usable range before interpolation. Clips are placed end to end with hard cuts; this tool does not add fades or remove silence. Check the join points by listening before downloading.
