One chain.
From input to output.

Edit without losing the original.: Changes live in an edit list. Undo them, copy them, or apply them to another recording.
Add only what you need.: Extend your chain with effects, analysis, and codecs from the @audio packages.
Let an agent run it.: AI agents drive the same chain through the CLI. Add npx -y audio --mcp as an MCP server, or give coding agents the skill: npx skills add audiojs/audio.

Use them together, or on their own.

Audio files in. PCM samples out.

Web Audio graphs in Node.js and CI.

Effects, analysis, synthesis, and codecs.
