Tips for Merging Audio
Arrange files in the correct order before merging. Use drag-and-drop to reorder tracks in the desired sequence.
Normalize volume levels across all clips before joining so the output has consistent loudness throughout.
Add brief silence (0.5–1 second) between tracks for natural breathing room, especially for spoken content.
If combining files with different sample rates, the tool resamples automatically, but matching rates ensures the best quality.
All audio merging is performed entirely in your browser. No audio data is uploaded to any server. Your files remain private on your device.
