The four kinds of AI mastering you can buy in 2026
Strip away the branding and the market sorts into four models, defined by two questions: how do you pay, and where does the processing happen?
1. Cloud services on subscription — you upload a track, a server masters it, and access is sold as a recurring plan. This is the biggest category: LANDR and eMastered are the best-known names. 2. Cloud services with a free tier — same upload-and-process flow, no required payment. BandLab Mastering is the serious one here. 3. One-time professional plugins — software you buy once and run inside a DAW, with AI-assisted analysis plus deep manual control. iZotope Ozone is the reference point. 4. One-time local apps — standalone apps you buy once that process the file on your own machine, no upload. That's the category our app Tonekai is in, and — as the comparison lists quietly confirm by omitting it — it's the least crowded of the four.
The subscription route: what you're actually buying
The subscription services are real businesses with real strengths, and the honest version of this article says so. LANDR in particular is not just a mastering engine: the subscription wraps in distribution, plugins, collaboration tools, and samples — an ecosystem, priced like one. eMastered ties unlimited mastering together with distribution and stem separation in its Studio plans, per its own help center.
What should give you pause is how hard it is to answer the basic question: what does it cost? As of this writing (October 20, 2026), LANDR's public mastering-pricing page displays no plan amounts at all without an account, and eMastered's plans article lists plan structures (monthly, yearly, yearly-billed-monthly) but no figures, deferring to the in-app purchase flow. We're not going to quote numbers we can't verify — that's exactly the game we think buyers lose. The structural point stands regardless of the current promo price: a subscription meters your access by time, and your releases don't happen on a timer. If you master two EPs a year, you're either paying through the quiet months or re-subscribing and cancelling like it's a gym.
When it's the right choice anyway: if you release frequently and you'd use the bundled distribution, the all-in-one plan can genuinely be worth it. That's a workflow decision, not a trap.
The free route: BandLab is a real option
Any honest comparison has to say this plainly: BandLab Mastering offers free mastering with unlimited WAV and MP3 downloads — four presets (Universal, Fire, Clarity, Tape) plus a mastering EQ on the free side, with four more presets and an intensity control reserved for the paid Membership, per its official FAQ. If your budget is zero and your priority is a louder, release-ready file, try it. It may be all you need, and we'd rather tell you that than pretend otherwise.
The trade-offs are about the flow, not the price. It's a platform service: you work in the browser or app, dropping your file into BandLab's system rather than processing it on your own machine. For a lot of users that's fine. It matters more if your tracks are unreleased and you care where they travel (we wrote about the cloud-versus-local question in depth), if you iterate heavily and want the master-listen-adjust loop to run at local speed, or if you'd simply rather not route your music through another platform account. Preset-based control also means you're choosing a flavor rather than letting the tool decide per-track — some people prefer that, some don't.
The one-time routes: plugin or app
If the subscription model is the mismatch, two categories fix it in different ways.
The pro plugin: iZotope Ozone 12 Standard is $219 as a one-time purchase (list price as of October 20, 2026; sales are common). You get an AI-assisted starting point and then every dial a mastering engineer could want, inside your DAW. The honest caveats: it assumes you have a DAW workflow and the appetite to learn mastering as a craft, and the price is positioned for people who'll use that depth. If that's you, it's a durable investment — this is the tool category much of the industry actually uses.
The local app: the fourth category — buy once, run on your own machine, no upload, no DAW required — is the one the comparison lists mostly skip, usually because the listicles are written about (and sometimes by) cloud services. Tonekai is our entry in it: a macOS app where you drop in a finished track and on-device AI adjusts loudness, tonal balance, and peaks automatically, with an A/B comparison before export. It's free to try, and Pro — WAV/AAC export and unlimited mastering — is a one-time $29.99 unlock (current Mac App Store price), not a plan. It's Mac-only (macOS 14+, Apple Silicon native), it masters the file you give it rather than offering a rack of tools, and if you want surgical manual control, Ozone is the better buy. What it optimizes for is the finish-a-track moment: file in, release-ready file out, nothing leaves your Mac.
The math that actually matters
Because current subscription figures aren't publicly verifiable, we'll keep the arithmetic structural — it's the structure that decides this anyway. A subscription's cost scales with time: every month you stay subscribed costs the same whether you mastered twelve tracks or none. A one-time tool's cost scales with nothing: it's a fixed number that stops mattering the day you buy it. Per-track services (where offered) scale with output, which sounds fair until you remember that mastering is iterative — the version you release is rarely the first pass, and paying per pass taxes exactly the experimentation that makes the result good.
So the question isn't "which is cheapest?" — it depends on your release rate, and the subscription services won't even hold their prices still long enough to chart. The question is: which cost model matches how you actually finish music? Steady releasers who want distribution bundled: subscription. Zero budget, comfortable with a platform flow: BandLab. Craft-minded, DAW-centered: Ozone. Finish-and-release on a Mac, files staying home, pay once: that's the corner we build for. One more honest note that applies to all four: mastering adjusts loudness, balance, and peaks — it won't repair distortion or artifacts already baked into the file. We keep a whole post on what mastering can't fix, and it applies to every tool on this page, ours included.
Where Tonekai fits
If the one-time local category is the one that matches your workflow, here's the shape of ours: Tonekai runs entirely on your Mac — tracks are never uploaded, which also means the iteration loop (master, listen, adjust, repeat) runs at local speed with no per-track cost and works offline. Drop in a file, compare before and after, export when it's right. Free to try with no account; Pro is a one-time purchase.

FAQ
Is free AI mastering good enough to release with? Sometimes, genuinely yes. Master a track with a free tool, listen on several systems next to a reference track you love, and let your ears vote — our guide to checking a master walks through how. If it passes, ship it. Tools earn their price only when you can hear the difference or feel it in your workflow.
Why does mastering even get sold as a subscription? Because recurring revenue is good for the seller, and because the big services bundle ongoing deliverables — distribution, samples, cloud storage — that genuinely are ongoing. If you'd use the bundle, the model can make sense. If you only want mastering, you're paying the bundle's rent.
Does "local" really matter if I'm releasing the track publicly anyway? Less for privacy, more for practicality: no upload queue, no re-encode in transit, offline use, and iteration at the speed of your own machine. For unreleased or client work, the privacy point returns with force. The full breakdown is in our cloud-vs-local comparison.
I master AI-generated tracks from Suno — does the payment model change anything? Mostly it compounds. Suno's own download limits (7 lifetime on free, 20/month on Pro, 60/month on Premier) make each exported file a budgeted asset, and iterating on a budgeted file with a metered mastering service stacks meter on meter. A tool with no per-track or per-month cost removes one of the two.
The bottom line
The AI mastering market defaults to subscriptions, but your options in 2026 are wider than the comparison lists suggest: a capable free tier exists, a one-time pro plugin exists, and one-time local apps exist. Match the cost model to your release rhythm and the processing location to your comfort — and whatever you pick, judge it with your ears against the free alternative before you pay anyone, us included.
