Audio and podcasting decision
SoundBoost.ai (formerly Diktatorial)
A capable technical user can reproduce the core mastering pipeline using existing open-source mastering software (matchering) and standard cloud infra; mobile apps, proprietary models, and product polish would be lost or costly to match.

No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Upload a track, enter a natural-language prompt or reference link, run a mastering pipeline to apply EQ/compression/saturation/limiter, then preview and export mastered files.
What it still won’t have
- Polished mobile apps (iOS/Android) and cross-device sync
- Proprietary trained mastering models and any vendor tuning
- Priority-queue/bulk-mastery features and advanced stem separation options
- The vendor’s UX polish, community trust, and ongoing model/engine improvements
What remains hard
- Product polish and ongoing maintenance

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self-hosted AI mastering web service using Python (FastAPI), Postgres, Redis, and AWS S3 for storage; use sergree/matchering as the mastering engine wrapped in a Docker worker. Core features in scope: file upload and storage, simple user accounts (email-only), accept a natural-language prompt and optional Spotify reference URL, queue jobs to a worker that runs matchering and converts outputs to WAV/MP3/FLAC using FFmpeg, provide preview streaming and file download, and enforce subscription gating via Stripe. Out of scope: native iOS/Android apps, multi-engine proprietary models, advanced stem-splitting UI. Include error handling, background job retries, and automated tests for upload, processing, and export flows.

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.
