Audio and podcasting decision
LANDR Studio
A focused DIY service that offers upload + automated mastering + limited distribution is realistic for a single technical user using third-party models/APIs, but replicating LANDR's proprietary mastering quality, massive sample library, and broad distribution partnerships is not practical to rebuild.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Allow a user to upload a track, run an automated mastering step, preview/download the mastered file, and optionally publish the release metadata to a small set of streaming platforms.
What it still won’t have
- Proprietary mastering model trained over a decade
- Distribution relationships / full coverage to 150+ platforms
- 3M+ premium, royalty-free sample library
- 70+ curated plugins and plugin marketplace
- 200+ online courses and learning platform features
What remains hard
- Proprietary models
our world-renowned mastering engine that never uses presets and has over a decade of AI training from pro audio engineers.
- Marketplace liquidity
release your music to over 150 streaming platforms
- Content rights
over 3 million premium, royalty-free samples

Runnable build prompt
Build a minimal self-hosted LANDR-like service using Node.js (Express), React for the frontend, Postgres for metadata, and S3-compatible storage for audio files. Implement: (1) user sign-up/login (email auth), (2) WAV/MP3 upload with server-side validation and storage, (3) a mastering worker that uses a configurable external mastering API (or local open-source model) to process files and store outputs, (4) a web UI for A/B preview, metadata entry, download, and queue/status, and (5) connectors to publish release metadata to 2 streaming endpoints (or a single aggregator API). Out of scope: building a proprietary mastering model, hosting a 3M sample library, plugin marketplace, and paid-course platform. Include error handling for file corruption, API failures, and storage limits; add automated tests for upload, processing workflow, and distribution connector; provide Docker Compose for local development and a Helm chart for production deployment.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
