How the audio joiner tool presents input and output.
One continuous timeline
Why use an online audio joiner?
Long narration is often recorded or generated in sections. Keeping every chapter, paragraph, or speaker turn as a separate file makes playback and publishing harder than it needs to be.
An audio merger places those clips in order and creates one continuous track. That is useful for combining text-to-speech generations, podcast segments, interviews, lessons, voice memos, and audiobook chapters.
This tool performs the join locally. You get the convenience of an audio joiner online without transferring private recordings to a remote processing service.
Four steps
How to combine audio files
- 01
Add two or more audio files
Choose WAV, MP3, M4A, or another audio format your browser can decode. Files stay on your device.
- 02
Arrange the playback order
Move each clip up or down until the list matches the order you want in the final recording.
- 03
Choose a gap and output format
Join clips directly or insert a short pause. Export a lossless WAV master or a smaller MP3.
- 04
Join, preview, and download
The browser renders one continuous audio file that you can listen to before downloading.
Common workflows
When joining audio saves time
TTS narration
Combine several character-limited speech generations into one lesson, article, or voice-over.
Podcast production
Place an intro, main segment, advertisement, and closing in the correct playback order.
Audiobook chapters
Merge short narration clips into a chapter and insert a consistent pause between sections.
Voice memos
Arrange several recordings into one briefing, study note, or personal audio journal.
Export decision
Join audio as WAV or MP3?
Choose WAV for editing
WAV is the safer master when you will add music, normalize loudness, remove noise, or make more edits. It is larger because the output is uncompressed PCM.
Choose MP3 for sharing
MP3 is smaller and easier to publish, email, and play on mobile devices. The joiner exports at 192 kbps, a balanced setting for speech mixed with music.

FAQ
Audio Joiner FAQs
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?
Choose WAV if you plan to edit or archive the combined audio. Choose MP3 when you want a smaller file for sharing, podcast publishing, or mobile playback.
06 Will the audio joiner change pitch or speed?
No. The clips keep their original pitch and playback speed. Files with different sample rates are resampled to a common rate so they can be placed on one continuous timeline.
07 How many clips can I combine?
The interface accepts up to 20 files and 300 MB total. Actual capacity depends on your device memory, so long uncompressed recordings are easier to process on a desktop computer.
