Four steps

How to combine audio files

  1. 01

    Choose your audio tracks

    Choose WAV, MP3, M4A, or another format your browser can decode. Files stay on your device.

  2. 02

    Set the track order

    Move each clip up or down until the list matches the order you want in the final recording.

  3. 03

    Choose a gap and output format

    Join clips directly or insert a short pause. Export a lossless WAV master or a smaller MP3.

  4. 04

    Combine, listen back, and download

    The browser renders one continuous audio file that you can listen to before downloading.

FAQ

Frequently asked questions

01

How do I combine audio files online for free?

Add at least two audio files, arrange their order, choose the gap and output format, then click Join Audio Files. The browser combines the clips locally and creates one downloadable file.
02

Can I join MP3 files and WAV files together?

Yes, provided your browser can decode each source. The joiner decodes the files to a common audio timeline and exports the result as WAV or MP3.
03

Are my recordings uploaded?

No. Decoding, arranging, and exporting happen in your browser. This makes the tool suitable for unpublished voice-overs, interviews, lessons, and personal recordings.
04

Can I add silence between audio clips?

Yes. Choose no gap or insert 0.25, 0.5, or 1 second between clips. Short gaps are useful when joining chapters or separate text-to-speech generations.
05

Should I export the joined audio as WAV or MP3?

Pick WAV if you plan to edit or archive the combined audio. Go for MP3 when you need a smaller file for sharing, podcasting, or mobile playback.
06

Will the audio joiner alter pitch or speed?

No. Clips retain their original pitch and playback speed. Files with different sample rates are resampled to a common rate so they fit on one continuous timeline.
07

How many clips can I combine?

The tool accepts up to 20 files, totalling 300 MB. Actual capacity depends on your device memory, so long uncompressed recordings are easier to process on a desktop.
