Free Mastering Studio
Grumpy Music’s Mastering Studio is a free, browser-based tool for mastering AI-generated music.

The simple view focuses on listening and choosing a sound. Opening a preset’s tool icon reveals the individual processors, with changes heard in real time.

Read update ↗Mini reviews
Mini reviews can be found under the "my reviews" page. It works like this: A separate AI system reads the review and finds the best quotes. You can choose between 3 quotes or generate new ones if you are unhappy with the result. You can then upload a cover image for the track or go with the standard grumpy music image. Download the image and simply share it on your social media of choice and upload a snippet of your track natively on that platform!
