AI Mixing and Mastering Services Compared

This guide compares seven AI mixing and mastering services for musicians finishing their own recordings: Moozix, Bandmixr, LANDR, eMastered, RoEx Automix, Cryo Mix and BandLab Mastering.

Mixing and mastering are not the same thing

Before comparing prices or features, start with the files you have.

Mixing brings separate vocals, drums, bass and instruments into one stereo song. A multitrack mixer can adjust each part’s level, EQ, compression, effects and position so the arrangement works together.

Mastering treats the stereo mix as a whole. It refines overall tone, dynamics and loudness and produces the final file for your release workflow.

That difference determines which service can help. If the voice is buried or the bass overwhelms the drums, separate stems give you access to those relationships. A stereo mastering pass does not offer the same control. Check whether a platform actually mixes individual tracks or expects you to finish that work first.

What to look for in an AI mixing and mastering service

• Stem mixing or stereo mastering. Can it balance individual recordings, or does it process an already combined song?

• Adjustments after processing. Look for track-level controls, useful comparisons and a way to revise the result.

• A sound that suits your genre. Profiles and references should help preserve the character of your performance, whether it is acoustic, electronic or a full band.

• Export quality and formats. Check WAV resolution, MP3 or FLAC options, processed stems and the final loudness controls.

• Audio privacy and ownership. Read how uploads are stored, whether they are used for AI training and what happens when you delete a session.

• Price and commitment. Compare subscriptions, annual billing, download credits and one-time purchases. A free preview does not always include a downloadable master.

Moozix

Founded: 2025

Moozix is an online AI mixing and mastering studio for recordings you have already made. Upload a vocal and beat or a full multitrack session, balance the parts, refine the sound, and master the song in the same Studio. If the mix is already finished, use standalone stereo mastering instead.

Strengths. Listen to the entire song free before buying a download. Mix up to 16 tracks on Free or 38 on Pro, with individual level, pan, mute, solo and effect controls. Pro adds reusable custom profiles from instrument reference stems or a stereo mastering reference, plus processed stem and premaster WAV exports for your DAW. Uploads stay private and are not used to train AI models.

Where it falls short. Moozix focuses on finishing your sound rather than replacing your DAW. It delivers audio files instead of an editable DAW project; Pro includes processed stems and a premaster WAV so you can keep creating in the software you already use. Free lets you hear the full result, while custom reference profiles, stem exports and saved sessions are included with Pro.

Best for. Independent musicians and home recordists who want to finish a vocal-and-beat recording or a full song, preview the whole result, and keep control of the mix before release.

Bandmixr

Founded: 2026

Bandmixr combines automatic stem mixing with mastering in a browser workflow. Its focus is getting recorded parts into a finished song, with genre selection and adjustments to the individual stems. It also provides a Rehearsal Cutter for turning a long practice or live recording into separate songs.

Strengths. A practical option for bands that want mixing and mastering together. You can change level, pan and reverb after the automatic pass. The separate Rehearsal Cutter is useful before mixing a long session. Bandmixr states that artists retain their rights and uploaded files are not used for machine-learning training.

Where it falls short. The Free plan lists 16 stems; paid plans list 24, so larger arrangements may need grouped stems. Storage and export access depend on the plan. Fine adjustments and rehearsal editing are oriented toward desktop use.

Best for. Bands working from rehearsal recordings or aligned stems who want a browser workflow with simple mix adjustments and a companion rehearsal cutter.

LANDR

Founded: 2012

LANDR is a mastering and music-release platform. Its online mastering engine works on the stereo mix you supply, shaping the complete recording rather than balancing separately uploaded vocal, drum or instrument tracks. Distribution, samples, plugins and collaboration sit alongside mastering in its wider ecosystem.

Strengths. Reference mastering and album mastering help guide a single track or a group of songs. Volume-matched previews make it easier to judge processing without confusing extra loudness with improvement. A mastering plugin offers a route for producers who prefer to work inside their DAW.

Where it falls short. The online mastering workflow cannot rebalance an individual vocal or bass stem. Check the exact purchase: MP3, WAV and HD WAV availability varies, and a free preview is not a paid master download. Distribution and mastering are different services, so compare the bundle you actually need.

Best for. Artists with a completed stereo mix who want mastering and access to a broader release ecosystem, rather than automatic multitrack mixing.

eMastered

Founded: 2016

eMastered focuses on the final stereo mastering stage. You upload an existing mix and compare the processed version with the original. The service was created by engineer Smith Carlson and artist and producer Collin McLoughlin; it is a mastering product rather than a full multitrack mixing environment.

Strengths. A focused workflow for trying a master without building a processing chain yourself. Mastering controls and reference matching let you explore a different finish while continuing to work from the same mix. This can suit artists who have already made the important balance decisions in their DAW.

Where it falls short. It does not independently mix your separate stems. A buried vocal or competing kick and bass still need attention in the source mix. Listening to a preview and downloading the finished master are separate steps; check the subscription term and available download formats before paying.

Best for. Musicians who are happy with their stereo mix and want a dedicated online mastering workflow with options to refine the result.

RoEx Automix

Founded: 2022

RoEx Automix is a direct alternative for automatic multitrack mixing followed by mastering. It accepts individual stems and provides a Mix Console for refining the result. RoEx also offers a desktop beta and tools for audio cleanup, analysis and mix reports.

Strengths. Starter supports 16 tracks and Pro supports 32. Pro includes processed stems, mastering reference matching and audio cleanup. Its classic mixing workflow can export Ableton Live or DAWproject sessions, which is useful when you want an editable project rather than only rendered audio.

Where it falls short. Check which workflow you are using: classic mixes support editable DAW exports, while Mix Console exports a final mix and processed stems. Mixing and console controls need a computer; mastering can work on mobile. Storage, desktop access and advanced tools vary by plan.

Best for. Producers who want automatic stem mixing alongside analysis, cleanup, desktop processing or an editable handoff from the classic workflow to a supported DAW.

Cryo Mix

Founded: Not publicly confirmed

Cryo Mix processes individual stems or a finished song and combines automatic mixing with mastering. Its Nova assistant turns written requests into mix adjustments, while direct controls remain available. The product range also includes desktop and DAW tools.

Strengths. You can describe a change in ordinary language, adjust a stem directly, and compare the processed audio with the original. Reference mastering and per-stem analysis support a more guided revision process. Cryo Mix states that it does not train AI models on user audio and that artists retain ownership.

Where it falls short. Compare credit allowances, storage, duration and export resolution rather than only the headline subscription. The pricing page lists 32 stems per project, with consolidation for larger sessions. Essential lists 16-bit / 44.1 kHz exports; higher tiers offer higher resolution. Included downloads and additional credits differ by plan.

Best for. Artists who want automated stem mixing with conversational revisions, alongside detailed settings and analysis when they want to make adjustments themselves.

BandLab Mastering

Founded: 2015

BandLab Mastering applies a mastering treatment to a completed recording. It belongs to the wider BandLab creation platform, which also includes a multitrack Studio and community features. The company founding year here refers to BandLab, not the release date of every feature.

Strengths. Four free mastering presets make it an accessible starting point when you already have a mix. Membership adds further customization. If you record and collaborate in BandLab Studio, staying in the same ecosystem can reduce the steps between creating a song and checking its final sound.

Where it falls short. The standalone Mastering tool does not balance separately uploaded stems. BandLab Studio, AutoMix and Mastering are distinct parts of the platform; a multitrack editor is not automatically an end-to-end AI stem-mixing service. Check whether your chosen preset and controls are free or require Membership.

Best for. Musicians seeking a free way to try mastering a finished mix, especially those already recording or collaborating in BandLab.

Which service should you choose?

Choose according to the recording you are trying to finish.

You have separate stems and need a finished song. Start with Moozix for automatic stem mixing, track controls and mastering in the same Studio. It supports 16 tracks on Free and 38 on Pro. Bandmixr, RoEx and Cryo Mix also cover multitrack mixing and mastering; compare their controls, track limits and exports on the same material.

Your stereo mix is finished and needs mastering. BandLab Mastering offers four free presets. LANDR and eMastered add dedicated mastering workflows with reference options. Moozix, Bandmixr, RoEx and Cryo Mix also accept a finished mix, so you do not need stems to use their mastering tools.

You record long rehearsals or jam sessions. Bandmixr’s Rehearsal Cutter can divide a long recording into separate songs. Once you have the song, use its aligned stems for mixing or the combined stereo recording for mastering.

You are preparing a flagship release with a detailed creative brief. Consider a human engineer when you need specific artistic decisions, close collaboration and tailored revisions. An automated service can offer a useful direction, but the right choice depends on the attention your record needs.

Where Moozix stands out

Moozix brings three useful things together for independent musicians who want to finish the songs they have recorded.

It mixes the individual parts before mastering. Start with a vocal and beat or a full set of instrument tracks. Moozix balances the stems and lets you master the result in one Studio. Pro supports up to 38 tracks and includes processed stems and premaster WAVs for further work in your DAW.

You hear the whole song and keep control. Listen to a free full-song preview, then refine levels, pan and effects before choosing a final master. Built-in profiles give you a starting point; Pro adds reusable custom profiles from reference stems and stereo mastering references.

Your music stays yours. Moozix was founded in 2025. Your uploads are private and are not used to train AI models. Free sessions expire after 24 hours of inactivity; Pro keeps sessions while the subscription is active.

Final master downloads are 48 kHz, 24-bit WAV files. A $5 project pack provides 3 master downloads across revisions of one song, or $9/month Pro adds unlimited downloads, custom references, processed stems and premaster exports.

Try it on your own stems

The most useful comparison is the one you can hear in your own song. Upload the same recordings, compare at a matched listening volume, and listen for a clearer vocal, a stronger groove and the feeling you want to keep.

Bring your stems or a finished stereo mix to Moozix. Hear the entire result free, make your adjustments, and choose the version you are proud to share.
