This repository hosts the demo application for the Chosen Masters B2B mastering API. It showcases the end-to-end workflow for requesting a signed upload URL, submitting a mastering job, and streaming mastered intensities with the same stack that powers the production dashboard.

Node.js 18 or newer (the project is built with the Next.js App Router)
npm 9+ (or an alternative package manager configured for Next.js projects)
Getting started

npm install
Create a .env.local file in the project root with the required configuration:
CM_API_KEY=
PARENT_BASE_URL=https://chosenmasters.com
NEXT_PUBLIC_MASTERING_CLOUDFRONT_URL=https://d2ojxa09qsr6gy.cloudfront.net
CM_API_KEY – Your private API key. Keep this secret and only reference it from server-side code.
PARENT_BASE_URL – The base domain for live API requests. Leave at the default unless you are targeting a staging stack.
NEXT_PUBLIC_MASTERING_CLOUDFRONT_URL – Public CloudFront distribution used for streaming mastered previews.
Start the development server:
npm run dev
Open http://localhost:3000 to view the demo. The interactive documentation is available at /mastering-docs and reflects the current production flow.
