About Audio Merger
Audio Merger joins multiple audio files into one track for podcasts, voicemails, and simple compilations.
Add your files, run merge, and download the combined result. Keep similar formats and levels when possible for smoother joins.
This is a sequential join, not a mixer with per-track effects. For complex crossfades, use a dedicated editor after export.
Example workflow
Select clips in the sequence you want and join them into one WAV download. For example, combine an introduction, interview and closing clip.
Output checks and limits
Processing uses your browser and available device memory. This is a sequential join, not a multi-track mixer; differing recording levels are not automatically normalised.
Benefits of Audio Merger
Frequently asked questions
Can I merge MP3 files online?
Yes - add the files, merge, and download the combined audio.
Will volumes match automatically?
Simple merges may not normalise loudness. Adjust levels beforehand if segments differ a lot.
