Merge audio files into one track
This free audio joiner combines multiple voice recordings, music clips, podcast segments, lessons, sound effects, or meeting notes in a chosen order. It accepts common formats your browser can decode, normalizes them to one project sample rate, and exports a single WAV file.
Files stay inside the current browser tab instead of being intentionally uploaded. Because audio decoding and merging use device memory, shorter projects are more reliable on mobile phones. Save the final result before closing or refreshing the page.
How to combine MP3, WAV, and audio clips
- Select two or more audio files from your device.
- Preview each clip and arrange the timeline with the order controls.
- Choose whether to insert silence between consecutive clips.
- Merge the timeline, preview the result, and download the combined WAV.
Tips for a smoother audio merge
Use clips with similar loudness and remove unwanted silence first with the Audio Trimmer. A short gap improves separation between spoken chapters, while no gap works for continuous recordings. This joiner does not apply loudness normalization or copyright-clearing.
