For independent musicians who want a release-ready master made by a real engineer, Sage Audio is the best online mastering service. A mastering engineer at our Chicago studio masters your song on analog and digital equipment for a flat $49 per song, with no subscription, and you can message your engineer and request revisions from your account. If you only need a free or instant master for a demo, an AI tool such as BandLab, LANDR, or eMastered is the better fit.

Three questions settle it for most artists.
Is this a release or a demo? For a rough demo or a social clip, a free AI master is fine. For a song you are putting on streaming platforms and promoting, the master is the last chance to fix problems, and that is where an engineer earns the fee.
Do you want someone to listen? An AI tool applies processing to whatever you upload. It cannot tell you the vocal is buried or the low end will fall apart on small speakers. An engineer can, and can tell you before the master is final.
How many songs do you release a year? Subscriptions suit artists who master many tracks a month. If you release a handful of songs a year, paying per song with no monthly fee is simpler.
We would rather you pick the right option - even if it isn't us.

How much does online mastering cost? AI mastering tools range from free (BandLab's basic presets) to about $10 per song or a monthly subscription (LANDR, eMastered). Mastering by a human engineer typically costs $50 to $200 or more per song. Sage Audio charges a flat $49 per song for mastering by an engineer.
Is AI mastering good enough for a commercial release? Sometimes. AI mastering can make a well-balanced mix louder and more polished, and many artists release AI masters. It cannot hear problems in your mix, respond to notes, or make judgment calls about your song. If the release matters to you, a human engineer is the safer choice.
What's the difference between AI mastering and mastering by an engineer? An AI tool analyses your file and applies processing automatically in minutes. An engineer listens to the song, chooses the processing for that song, can flag mix problems before mastering, and revises the master based on your feedback.
