Key takeaways

• LANDR is the best AI mastering service for most musicians: it offers per-track or subscription pricing, album mastering, reference mastering, and unlimited free previews and revisions.

• iZotope Ozone 12 is the pick if you'd rather master inside your DAW, with an assistant that sets a full chain you can then adjust module by module.

• Waves Online Mastering exports up to 24-bit, 96kHz WAV and is the cheapest per track when credits are on sale.

What AI mastering does

Mastering is the last step before release: it sets a track's overall loudness, tonal balance, stereo width, and peak level so it sounds right on streaming services, headphones, and car speakers. An AI mastering service analyzes your mix and applies a chain of EQ, compression, and limiting for you, usually in under a minute. Most let you steer the result with a style or intensity setting, and the better ones match a reference track you upload. None of them can fix a bad mix, and a human engineer still catches problems an algorithm won't. For demos, singles, and most independent releases, though, an AI master costs a fraction of what a human engineer charges.

How we ranked

We looked at sound quality and independent listening tests, how much control you get over the result, reference-track matching, album and batch mastering, export formats and resolution, free previews and revisions, and price per track or per year.

The seven services compared

1. LANDR - Best overall

LANDR is a music platform whose AI mastering engine has run on millions of tracks since it launched in 2014.

What works: Upload a track and LANDR builds a mastering chain for it, then lets you pick a style and loudness and compare versions in a volume-matched A/B player. You can also master to a reference track or master an album so the songs sit together. Previews and revisions are free and unlimited, and you don't pay until you download. A single master costs $10, or you can subscribe to LANDR Studio, whose higher plans add WAV and 24-bit HD WAV masters plus a mastering plugin for your DAW. It accepts WAV, AIFF, FLAC, and MP3.

What doesn't: In musician Benn Jordan's 2024 blind test of AI mastering, LANDR's master was cut before the final round, and the cheapest Studio plan includes MP3 masters only.

Best for: Independent artists who want a reliable master without learning to do it themselves.

2. iZotope Ozone 12 - Best for mastering inside your DAW

Ozone is iZotope's mastering plugin suite, and version 12 is its newest. iZotope is now owned by Boris FX.

What works: Master Assistant analyzes your track and builds a full chain, and a new custom flow lets you choose from dozens of genre targets or your own reference, set a LUFS loudness target, switch modules on or off, and set how strongly it processes. Ozone 12 adds a new IRC 5 limiting mode to its Maximizer, and the Advanced edition adds Stem EQ, which adjusts vocals, bass, drums, and other instruments inside a finished stereo mix, plus an Unlimiter that restores dynamics to over-compressed audio. Because it runs in your DAW, every setting stays editable. Standard costs $219 and Advanced $499, as one-time purchases that often go on sale.

What doesn't: The cheapest Elements edition gives you the assistant without access to individual modules, and getting the most out of Ozone takes some mastering knowledge.

Best for: Producers who want an AI starting point and full control after it.

3. Waves Online Mastering - Best for hi-res exports and low per-track cost

Waves is a long-running audio plugin maker, and Online Mastering is its browser-based AI service.

What works: You choose one of three styles, Precise, Organic, or Elevating, add Presence or Depth to shape the tone, and can upload a reference track. It exports WAV or MP3 at 44.1, 48, 88.2, or 96kHz in 16- or 24-bit, the widest range of formats here. You get a free 30-second preview with unlimited revisions, credit packs need no subscription and don't expire, and Waves claims no rights to your music. Credits were on sale at $3.99 each when we checked, and subscriptions run from $71.64 a year for 36 masters to $169.99 a year for unlimited.

What doesn't: There's no LUFS target setting, so loudness follows the style or your reference, it handles stereo and mono only, and credits that come with a subscription are lost if the subscription ends.

Best for: Musicians who need high-resolution masters for many tracks at a low cost.

4. eMastered - Best for mastering plus distribution in one plan

eMastered is an online AI mastering service founded by Grammy-winning engineer Smith Carlson and Collin McLoughlin.

What works: It masters to a reference track or on its own, then gives you manual controls for strength, EQ, compression, stereo width, and volume, and lets you save your settings as presets. Previews are free and unlimited. Its single Studio plan includes unlimited mastering and unlimited distribution to streaming services under a fair-use policy, plus stem separation and other tools, for $15 a month billed yearly, $19 a month on a yearly commitment billed monthly, or $39 month to month. There's a 14-day refund if you've downloaded fewer than four masters.

What doesn't: There's no pay-per-track option, and the month-to-month price is more than double the yearly rate.

Best for: Artists releasing regularly who want mastering and distribution on one bill.

5. Masterchannel - Best for an engineer-modeled sound

Masterchannel is a Norwegian AI mastering service built around sound profiles modeled on working mastering engineers.

What works: Its AI pairs with profiles based on engineers including Simon Hestermann and Wez Clarke, and you steer the result by genre and mood while loudness meters show how the master will play on streaming services. Every plan includes EP and album mastering, bulk mastering, and unlimited downloads, and you keep full ownership of your masters. The Artist plan costs $15 a month billed yearly, and Professional, at $19, adds the Wez Clarke profile and post-master tweaks. It also powers TuneCore's mastering, where a single song costs $5 with free full-length previews.

What doesn't: Its plans are priced around yearly billing, and it gives you less hands-on control than eMastered or Ozone.

Best for: Artists who want a master shaped by an established engineer's taste.

6. BandLab Mastering - Best for free mastering

BandLab is a free music-making platform, and its mastering tool works in the browser and the mobile app.

What works: Upload a track, pick a free preset such as Universal, Fire, Clarity, or Tape, and compare it with your original before you download, all at no cost. You can master a whole album at once, and on mobile you can export a video for social posts. A paid BandLab Membership adds four more presets and an intensity control, and the top Max tier adds a three-band mastering EQ and reference mastering.

What doesn't: The free version offers presets only, with no reference matching or fine control, and the result is a starting point more than a finished release master.

Best for: Beginners and anyone mastering demos without a budget.

7. Matchering 2.0 - Best for free reference matching

Matchering is a free, open-source tool that masters your track to match the sound of a reference song you choose.

What works: It matches the loudness, frequency balance, and stereo width of your reference, and in Benn Jordan's 2024 blind test of AI mastering, voted on by 472 listeners, it placed third, behind only two human engineers and ahead of Ozone 11. It's free under the GPL-3.0 license and runs as a Docker web app, a Python library, or a ComfyUI node.

What doesn't: You have to install and run it yourself, it has no styles or presets, and the result depends heavily on picking a good reference.

Best for: Technical producers who want a strong free master and don't mind setup.

Other options worth knowing

If you produce in Logic Pro, its built-in Mastering Assistant is free, with four characters (Clean, Valve, Punch, and Transparent), though three of them need a Mac with Apple silicon. DistroKid's Mixea masters your first track free, then costs $99 a year for unlimited masters at 24-bit, 48kHz. FL Studio users get mastering through FL Cloud, which took over CloudBounce's engine after Image-Line acquired it and shut down the standalone service. RoEx Automix mixes multitrack sessions and masters them on its Pro plan.

Is AI mastering as good as a human engineer?

Not yet, at the top end. In Benn Jordan's 2024 blind test, two human mastering engineers took first and second place, ahead of every AI tool. The test used a single track and predates the newest engines, including Ozone 12, so the gap may be smaller now. For most independent releases, a good AI master is close enough, and far cheaper, but an album you've invested heavily in is still worth sending to a human engineer, or at least comparing against one.
