MixAudio
MixAudio generates royalty-free music from text, images or reference audio using its own Blockmusic AI engine, then lets you remix tracks, edit stems and stream endless AI radio sessions. A permanent free plan is available.
What is MixAudio?
MixAudio is an AI music service built by Neutune, Inc. around its own engine, Blockmusic AI. Rather than rendering audio end to end from a single prompt, the engine assembles what the company calls music blocks, samples produced jointly by human artists and algorithms, and synthesises them into a finished track. The publisher likens the method to building with LEGO bricks, which is where the Block Music name comes from.
Its most distinctive trait is multimodal input. You can describe the music you want in text, upload an image, supply a reference audio file, or combine all three in the same request. The company presents this as a world first and claims several usable variations in under three seconds.
The product is organised into four areas. AI Soundtrack handles generation from prompts. AI Remix starts from a referenced artist or song and regenerates it in another style, with a side for fans and a side for artists. AI Radio streams continuously generated sessions around the clock and underpins the company's move towards adaptive music sold through B2B deals and an API. Sounds is a sample and sound-effect library with search and generation. Behind all four sits an interactive studio where sections can be edited, stems layered or regenerated, and tempo, key and pitch adjusted after the fact.
The blocks themselves come from Block Music Artists, producers who supply material under licensing agreements the company describes as fair and who share in the revenue; musicians apply by email. That sourcing underpins MixAudio's copyright position: it states that all data used to train and run the engine is either created in-house or licensed, and its own blog contrasts this with competitors facing litigation.
The tool targets creators without musical training and responds better to moods, themes and scenes than to technical briefs; the publisher openly concedes weaker results on unusual instruments and culturally specific styles. At the time of review the homepage had shifted to a waitlist for a major update announced for Q3 2026, while a parallel conversational service, mixaudio: AI Music Agent, runs on a separate subdomain with token-based billing.

When to use MixAudio / When not to
A quick filter to help you decide if MixAudio is the right fit.
When to use MixAudio
- YouTube creators and short-form video makers who need a soundtrack that will not trigger a copyright claim
- Podcasters looking for intros, beds and outros they can monetise on every episode
- Video editors and motion designers who want to adjust sections, stems and tempo after generation rather than start again
- Agencies and studios producing client work, advertising and branded media, which the Professional tier explicitly covers
- Indie game developers who need background music cleared for commercial release
When not to use MixAudio
- Anyone planning to sell or distribute the music on its own, which the licence forbids on every tier, altered or not
- Composers who need precise control over individual instruments, MIDI or sound levels: the engine answers to moods and scenes, not technical briefs
- Creators working in culturally specific styles or with unusual instruments, a limitation the publisher openly concedes
- Personal-tier subscribers running paid advertising or brand promotion, which is reserved for the Professional tier and above
- Teams with strict GDPR procurement requirements, since no DPA, no subprocessor list and no hosting location are published
How to use MixAudio
A typical end-to-end flow, from setup to results.
- Create an account with an email address, or sign in with Apple or Kakao
- Answer the two-question welcome survey, which credits 20 free credits to your account
- Open the creation screen and describe the music you want; a mood, theme or occasion works better than a technical brief
- Optionally attach an image and a reference audio file, which can also be pasted as a YouTube or SoundCloud URL
- Switch on XR Sound if you want ambient elements such as birdsong or running water written into the track
- Use Prompt genius if you would like the tool to rephrase your prompt for you
- Listen to the variations returned, then open the studio to edit sections, stack stems or regenerate the parts you dislike
- Adjust global settings such as BPM and key, or run stem separation and pitch correction
- Download the result as MP3 or WAV; downloads consume credits and become unlimited from the Personal tier
- Musicians wanting to supply blocks apply separately through MixAudio for Artists, by email with an [Artist Application] subject line
Pros & Cons
Pros
- Multimodal input is genuinely uncommon: text, image and audio can be combined in the same request
- Generation is fast, with the publisher claiming several variations in under three seconds
- A clear copyright position: the training corpus is created or licensed in-house, unlike competitors the company itself names as being in litigation
- The free plan is permanent rather than a countdown trial, and it allows limited downloads and monetisation
- Real post-generation editing of sections, stems, tempo and key, where many generators stop at the output
- Annual billing is substantially cheaper: USD 95.88 a year against USD 179.88 paid monthly on the same tier
- External recognition, with a CES 2023 Innovation Award and a German Design Award in 2024
Cons
- The terms grant MixAudio a worldwide, free licence over the music you create, derivative works included
- No GDPR apparatus at all: no DPA, no subprocessor list, no Article 27 representative and no dedicated contact
- The hosting location of user data is never disclosed, and there is no trust or security page
- Both the privacy policy and the terms can change without notice, and the service can be discontinued without notice or liability
- Refunds are narrow, limited to seven days and only where nothing has been downloaded, and credits expire after a year
- The App Store and Google Play links shown on the homepage both return a 404, so the advertised mobile apps cannot be obtained
- Two pricing systems coexist without explanation, credits on mix.audio and tokens on the agent service, while the API documentation is still marked Coming Soon

Data, GDPR & hosting
A consolidated view of how MixAudio handles your data.
GDPR overview
There is no GDPR implementation to report. Targeted searches across the privacy policy, the terms of use and the application bundle return no mention of the GDPR, SOC 2, ISO 27001 or the CCPA. No data protection officer, no Article 27 representative in the European Union, no data processing agreement and no subprocessor list are published. The privacy policy does grant rights, but on its own terms rather than the regulation's: disclosure on request (article 5), correction and deletion (article 6), and suspension of processing when data is used beyond its purpose or obtained unlawfully (article 7). Disclosure may be refused, and identity checks or postage costs may apply. Korean law governs the terms, and European consumers are explicitly denied a right of withdrawal.
Who owns the data?
MixAudio keeps every intellectual property right attached to the service itself, including copyrights and trademarks. More consequentially, article 5 of the terms of use has you grant the publisher a worldwide, non-exclusive and free licence over any music you create with the tool, covering reproduction, distribution and derivative works. Artists uploading through MixAudio for Artists keep the copyright on their files, but the platform receives broad commercial and non-commercial rights to stream, sell and distribute them. In practice you own your output in the sense that you may use it, while Neutune retains a parallel right to exploit it.
Reuse rights
Downloaded tracks are royalty-free and can be reused without asking further permission, within the boundaries of the tier you paid for. The free and Personal tiers allow monetisation on a single channel per platform; the Professional tier lifts that limit and adds advertising, client work, apps, websites, indie games and corporate or branded media, together with a certified licence PDF. Selling or distributing the music on its own stays forbidden everywhere, modified or not, because it is licensed as background music. Content published while the subscription is active remains online after cancellation, but downloaded files may no longer be used in new productions.
Data retention & training
Hosting summary
MixAudio publishes nothing about where user data is hosted. Neither the privacy policy nor the terms of use names a country, a region or a cloud provider, and the site has no trust or security page. No subprocessor list and no data processing agreement are offered. What can be observed is purely technical and is not a statement by the publisher: asset and blog files are served from an AWS bucket in the ap-northeast-2 region, and the site itself is delivered by a CloudFront edge node that resolved in Switzerland on the day of review. The legal entity named in the footer, Neutune, Inc., is registered in Delaware, while the terms of use place the contract under the law of the Republic of Korea. Anyone with a hosting requirement will have to ask directly, because nothing published on the site answers the question.
Things to keep in mind
Risks and trade-offs to weigh before adopting MixAudio.
- The licence you grant on your own creations is worldwide, free and covers derivative works; read article 5 before using the tool for anything you consider proprietary
- Leaning on instant generation can quietly erode the habit of composing, arranging or briefing a musician yourself
- Both the privacy policy and the terms can be rewritten without notice, so the agreement you accepted today may not be the one binding you next month
- The service may be discontinued at any time without notice or compensation, so a production pipeline built on it needs a fallback
- Credits expire after a year and refunds are limited to seven days with no download history, which penalises stockpiling
- After cancelling you may keep published content online but may no longer use downloaded tracks in new work, an easy rule to forget mid-project
- With no stated hosting jurisdiction and no GDPR paperwork, you cannot document to a client where their audio and your account data actually sit
Setup & Integrations
Technical difficulty
Very low. MixAudio is a browser-based application with nothing to install: you sign up with an email address, an Apple account or a Kakao account, answer a two-question survey and start prompting. No musical training is expected, since the engine is explicitly designed for creators who lack musical vocabulary, and abstract prompts about mood or scene work better than technical ones. The only part requiring real engineering effort is the Blockmusic AI API, which is reserved for the Enterprise tier and whose documentation was still marked Coming Soon at the time of review.

Should you pick MixAudio?
MixAudio occupies a defensible niche among AI music generators. Where much of the field is fighting over the provenance of its training data, Neutune built its engine on blocks supplied by paid artists and states that everything it trains on is created or licensed in-house. For a creator whose real fear is a copyright claim on a monetised video, that positioning matters more than raw audio fidelity.
The second argument in its favour is what happens after generation. Sections, stems, tempo, key and pitch can all be reworked in the studio, and stem separation is included. Many rivals hand you a finished file and invite you to try again; MixAudio lets you fix the take you almost liked. The permanent free plan makes that easy to test without a card.
The reservations are mostly contractual. Article 5 of the terms grants the publisher a worldwide, free licence over the music you create, derivative works included, which deserves a careful read before the tool goes anywhere near proprietary work. There is no GDPR apparatus whatsoever, no stated hosting jurisdiction, and both the policy and the terms can be rewritten without notice.
There is also genuine uncertainty about the product's shape. The homepage has become a waitlist for a major update promised for Q3 2026, a parallel AI Music Agent service runs on its own subdomain with a different, token-based price list, and the mobile apps still advertised on the homepage no longer exist on either store.
Worth trying if you produce video, podcasts or games and want a soundtrack you can defend. Worth pausing over if you need documented data governance, or if you cannot accept a broad licence on your own output.
