MasteringBOX review
A practical AI mastering service with album tools, loudness control, and flexible output tiers.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
MasteringBOX is a browser-based AI audio mastering service for independent artists, producers, and small studios. It analyzes dynamic and spectral audio characteristics, applies automated mastering, and lets users compare the original and mastered versions. Album and project organization, track sharing with an audio player and artist profile, metadata, cover-art embedding, and downloads in M4A, MP3, WAV, and HD WAV formats make it suited to creators managing releases across web and Android.
The pricing structure is designed to let users start with limited mastering before moving into higher-volume plans. The Free plan provides one master per day, 90-day storage, Loudness Control, and album creation. Basic costs €6 per month with annual billing and adds unlimited MP3/M4A mastering, 180-day storage, EQ Control, cover art and ID3 tags, and basic support. Pro costs €9 per month with annual billing and includes three WAV/HD masters per month, 360-day storage, advanced mastering settings, and premium support. Unlimited costs €19 per month with annual billing and adds unlimited mastering in all formats and unlimited storage.
Its strongest fit is for mobile-oriented album and project workflows that benefit from automated processing plus a small amount of manual control. Loudness Control and three-band dynamic EQ controls give users adjustment options beyond a single automated result, while before-and-after comparison helps with review. The tier differences matter most for output format and volume: Basic suits MP3/M4A projects, Pro adds a limited number of WAV/HD masters, and Unlimited removes the format and storage limits. Choose MasteringBOX for organized, AI-assisted release preparation on web or Android; choose another option if your workflow depends on capabilities outside its listed mastering, organization, sharing, and download features.
