eMastered review
Online AI mastering with distribution, stem separation, and creator-focused production tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Sep 2026
eMastered is a web-based AI mastering service for musicians, producers, and other music creators. Users upload a stereo audio file for online processing that can include equalization, compression, volume normalization, and stereo enhancement. Reference-track mastering lets creators provide another song as a sonic guide, while adjustable controls provide additional influence over compression, EQ, stereo width, and volume. Uploads can use AIFF, WAV, or MP3 files, and completed masters are available as WAV and MP3 downloads.
The main strength is the combination of automated mastering and creative control. eMastered supports reference tracks instead of limiting users to a single fixed processing approach, and its stem separation feature can separate vocals, drums, bass, and other parts. The category specification marks stem mastering as false, so the service is better understood as stereo mastering paired with stem-separation utilities rather than a stem-by-stem mastering system. The web platform keeps the workflow browser-based, while the ATOM Synthesizer VST/AU/AAX extends the related production tools beyond the mastering page.
Its Studio offering broadens the product into a music-release workspace. Studio — Monthly, Studio — Yearly, and Studio — Yearly billed monthly each list unlimited mastering, unlimited distribution, unlimited stem separation, ATOM Synthesizer, and Linkify. Distribution Pro lists unlimited distribution, making it the narrower option for creators focused on releases rather than the full Studio tool set. The freemium model provides an entry point, while the plan structure suits users who want mastering and distribution together. Choose eMastered for browser-based AI mastering with reference tracks and release tools; choose an alternative if native desktop access or true stem mastering is central to the workflow.
