Technical Guide
How Audio Merging Works
Our audio merger concatenates multiple audio files into a single output file using FFmpeg WebAssembly.
Seamless Joining
The merger joins files end-to-end without introducing gaps or clicks between tracks. The transition is seamless.
Format Handling
When merging files of different formats, all files are decoded and re-encoded to your chosen output format. For best quality, use files with similar sample rates.
File Order
Drag files up or down to set the playback order. The first file in the list plays first in the merged output.
Tips for Best Results
- Use consistent formats - Files with the same sample rate and codec merge most cleanly
- Preview the order - Listen to each track to verify the correct sequence
- Consider transitions - If you need crossfades between tracks, use a full DAW
