An AI mix and master chain bills in three different ways

The audio task

Finishing a release with AI-assisted help rarely means buying one product. A producer might use a restoration or dynamics plugin bought once, an online or in-DAW mastering service billed monthly or yearly, and a per-track service that charges for output rather than access. Each vendor prices its own piece of that chain differently, and the real cost of finishing a release is the sum of however many of those pricing models a producer actually uses, not a single sticker price.

What the documents show

sonible's shop page sells its smart: and pure: series plugins, such as smart:EQ 4 and smart:comp 3, as one-time purchases priced at $129 each at the time of retrieval, with bundles priced separately; nothing on the page describes a subscription. LANDR's pricing page is built around ongoing access: its own call to action invites a visitor not 'ready for a subscription' to open a free account instead, framing its mastering, distribution, and plugin tools as subscription products, though the page's visible text does not list every plan's price. eMastered's own help-centre article describes Monthly, Yearly, and 'Yearly (billed monthly)' Studio plans, and a companion article on the same help centre states that eMastered's Yearly plan is 'a one-time payment of $156,' shown as $13 a month only to illustrate the annual saving.

Rights status

None of these three pages addresses ownership of the mastered or processed audio; in each case, a purchase or subscription is a licence to use software or a service, not a rights transfer in the release itself. This note describes billing structure only, as each vendor's own current page states it, retrieved 16 September 2026; it does not verify that any plan grants a specific output-rights scope, which a producer should confirm separately in each vendor's terms of service.

What to check before you use it

This is an editorial method record built from named vendors' own current pricing pages, not a claim about typical total cost. Before assembling a chain, list every tool by its billing type, one-time, monthly, or yearly, check whether a lapsed subscription removes access to previously processed files, and total the actual recurring cost across a full release cycle rather than comparing sticker prices in isolation.

• Is this tool a perpetual purchase, or does access end if a subscription lapses?
• Does the vendor's own pricing page state the current price in the studio's billing currency, or only a promotional figure?
• Would a one-time restoration plugin plus a per-track mastering charge cost less over a year than an always-on subscription bundle?

A chain assembled from several vendors' own pricing pages is more transparent than a single quoted mastering cost, but only if each page is checked again at the time of budgeting, since living pricing pages change.
