Web-based AI mastering vs MixMaster Pro, which analyzes the mix first, then masters it with a level-matched preview. What each tool is for, and when to choose which.
MixMaster Pro is the living Mix Intelligence platform for producers. Analyses stay in your Mix Library, revisions compare on the same mix, references save to your account, and Maya on Pro+ coaches from your bound report - connected workflows instead of one-time uploads. The same account also runs Audio Tools and Workflow Builder: AI mastering, stem splitting, karaoke, a capella, guitar chords and lyrics, Sound FX, song generation, voice cleanup, and audio restoration.
Waves Online Mastering, listed on waves.com as AI Mastering Online, is a web-based AI mastering service from Waves Audio. Users shape the master with style, tone and reference inputs. (Details checked on Waves Online Mastering's own public pages, November 2026.)
On MixMaster Pro, Mix Analysis tells you what to fix before mastering. The Mastering Suite then prints the master: set the intent, preview a level-matched before / after, and download a 24-bit WAV. Delivery Master applies a streaming loudness pack to a master that already sounds right.
Our recommendation
Choose Waves Online Mastering when you want an online master with high sample-rate export options. Choose MixMaster Pro when you want to check the mix before the master and keep the analysis, the master and a streaming pack on one account.
