One Master review
Pay per song for AI mastering with reference matching, stem processing, and WAV export.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
One Master is a browser-based AI mastering service for musicians, producers, and labels. It processes finished stereo mixes or separate beat and vocal files, then provides a full-result preview before download. Its workflow includes reference track matching, loudness normalization, LUFS metering, 24-bit WAV export, and three free revisions on the same files. A browser-based Studio workspace also adds recording, multitrack editing, mixing, and export capabilities.
The pricing model suits artists who prefer one-time purchases over subscriptions. The Single plan costs $9.90 per song and includes unlimited free listening, a 24-bit WAV download, three free revisions, permanent file storage, and no expiry date. Creator costs $24.90 per three songs, Pro costs $54.90 per eight songs, and Studio costs $89.90 per 15 songs; each includes 24-bit WAV downloads, three free revisions per master, and no expiry date. Studio Pass options cost $10 for one project slot or $20 for three project slots, each covering 30 days with open export and included song credits. Label / Enterprise has custom pricing.
One Master is a good fit for solo artists, producers, and small teams that need reference-aware mastering, stem processing, and downloadable WAV files without recurring billing. The separate beat-and-vocal workflow gives it more scope than a stereo-only mastering service, while the Studio workspace extends it into browser-based production. It is less suitable for buyers seeking a free tier, a desktop-centered workflow, or standard published pricing for enterprise use. Email and phone support are available, and the service offers a 14-day refund period.
