How many files can I merge?

You can merge several audio files at once; each file can be up to 100 MB.

What is a crossfade?

A crossfade smoothly blends the end of one clip into the start of the next so there is no hard cut between them.

Every tool here is also available to AI assistants and developers via our MCP server and REST API.
