Questions and practical tips

Does file order matter?

Will merging improve audio quality?

No. The result depends on the original recordings and export settings. Re-encoding with a lossy format may introduce additional quality loss.

Processing and file safety

This tool processes files in your browser. Loading the page, libraries or AI models can still require network connections. Keep a copy of your original files and check the downloaded result before deleting them. Large files may require more memory and processing time than your device can provide.
