A closer look at Maastr
Maastr is an online AI mastering service tuned for loud music, built around the mastering process of producer Jay Maas. Users upload a WAV or MP3 track, the engine boosts loudness while preserving clarity and dynamics, and the finished master can be downloaded and compared within seconds. Maastr also adds collaboration for sharing tracks, managing versions and collecting feedback in one place. The homepage needs no credit card to start, but shows no prices, so costs must be confirmed.
