Will this crush my dynamics?

No. MasterSauce targets streaming loudness norms (Spotify, Apple Music, YouTube) which are actually moderate. The engine preserves punch and dynamics — it's not a brick wall limiter. If your mix is already well-balanced, the master will feel louder and cleaner, not squashed.

What if my mix isn't perfect?

That's exactly who this is built for. You don't need a perfect mix to get value from mastering — the engine adapts to your genre and loudness preset. A/B the result before you commit. If it doesn't lift the track, don't export.

Is this just for AI music?

No. MasterSauce works for any mix — bedroom recordings, live instruments, full band productions, or AI-generated tracks. The genre presets cover Pop, Hip-Hop, EDM, Rock, Reggaeton, R&B, and Lo-Fi.

Can I hear the result before paying anything?

Yes. Upload your mix, run the analysis, and A/B preview as many times as you want — completely free. You only use your export allowance when you download the final master.

Do I lose rights to my song?

Never. You retain 100% ownership. MasterSauce processes your file to generate previews and your export, then it's gone. We are a tool, not a rights holder.

What's the difference between the free plan and paid?

Free gives you 2 full WAV exports per month at 16-bit — enough to test the workflow. Creator ($9/mo) adds 15 exports, 24-bit WAV, and adaptive customization. Pro Studio ($24/mo) goes up to 60 exports and 32-bit float for batch work.

An in-browser mastering tool: upload your mix, choose genre and loudness, run a short analysis, then A/B the recommended master (or optional adaptive customization on paid plans). When you like what you hear, export the full-resolution WAV.

Do you keep my audio?

Files are processed to build previews and your export; we do not treat uploads as a personal music library. Retention details are in the Privacy Policy if you need the fine print.

WAV or MP3 within the limit shown in the uploader. A quick analysis checks loudness and headroom, then mastering follows the genre and loudness preset you selected.

What creators are saying

From bedroom producers to release-ready artists — across genres and languages.

"I've tried a few online mastering tools before, but this one gave my track more clarity, punch, and balance without destroying the vibe. The low end felt tighter, the vocals sat better, and it finally sounded ready for release."

James T.Austin, USA · Hip-Hop

"What I liked most was that the mastering improved the sound without making it feel overprocessed. It sounded cleaner, louder, and much more professional right away."

Daniel R.Miami, USA · Pop

"Probé la masterización y se notó rápido la diferencia. La canción sonó más clara, con más fuerza y mejor balanceada. Lo mejor fue que no perdió su esencia."

Carlos M.San Juan, Puerto Rico · Reggaeton

Need more finals this month?

Credit pack — $4 one-time

Adds five more full WAV exports. We always use your plan allowance before touching credits.

What actually uses my monthly allowance?

Each finished, full-quality WAV download. Generating previews, switching genres, or A/B listening does not.

Do previews use my quota?

No. Preview as many masters as you like — the counter moves only when you export a final file.

Can I buy extra exports mid-month?

Yes. One-time credit packs add five more finals and stack after your plan allowance.

Can I cancel anytime?

Yes. Manage or cancel inside the Stripe customer portal whenever you need.

Adaptive customization

Add a short written brief and the engine reshapes loudness, tone, and punch around your mix — still previewed with the same A/B player before you spend an export.

Recommended masters remain the fast default on every plan; adaptive is an optional layer when you want hands-on direction without building a plugin chain.
