Maastr

What is Maastr?

Maastr is an online audio mastering platform that uses an AI-powered engine to automatically enhance tracks. You upload an audio file, and the platform returns a mastered version within minutes. It handles a wide range of genres and styles, with tools to refine mixes no matter what kind of music you make.

Collaboration is built in: clients and collaborators can leave detailed notes on a mix, which makes precise adjustments easier. Every revision is stored, so you can compare, access, and play back different versions of a track. Maastr is aimed at both seasoned sound engineers and musicians, speeding up the mastering process, smoothing communication, and removing the need for expensive, time-consuming manual mastering.

Who created Maastr?

Maastr was developed by a team led by Dan Korneff of House of Loud Studios and launched on January 27, 2022. The team consists of mixing and mastering professionals who set out to make premium-quality mastering simple and accessible, delivering results in minutes through the AI engine.

How to use Maastr?
