What exactly did Musik Hack build?

HyFi is the new browser-based mastering platform from Musik Hack, the company behind the mixing plugin Master Plan. There's nothing to install: drag a track into the browser on desktop, tablet or phone, pick a Loudness setting (Balanced, Full or Loud) and a Character setting (Bright, Warm or Glue), and HyFi returns a master you can A/B against a gain-matched version of your original. Pricing runs on credits instead of a subscription. One credit equals one minute of processed audio, individual credits cost roughly $0.33 to $0.50 depending on how many you buy, and a full track can come out the other end mastered for as little as $0.99. Every new account starts with 10 free credits, masters are stored for 30 days, and the first revision after your initial pass is free, with each one after that costing another credit. Crucially, Musik Hack says HyFi runs on the same DSP as Master Plan itself, not AI, per MusicRadar, what the company calls "Master Plan on the go." The public rollout, covered this week by Sound on Sound and MusicRadar, followed a VIP soft launch for early testers.

Why does it matter that it's a credible engineer's DSP, not a random algorithm?

Cheap automated mastering has existed for years through services like LANDR. What's different about HyFi is the name attached to it. Master Plan was built by Grammy-nominated engineer Stan Greene, who has worked with Rihanna, Big Sean and Snoop Dogg, alongside composer and developer Samuel Fischmann, and it has earned real respect among mixing engineers since it launched in 2023 at $50 a year or $125 for a permanent license. Putting that same processing behind a $0.99 pay-as-you-go price, explicitly not AI, is a different proposition than a black-box startup promising a magic master. It's the kind of legitimacy that makes "just run it through HyFi" a genuinely credible answer to "who's mastering your EP," not an obvious shortcut. That is the same pressure TTH has tracked elsewhere this year, from AI stems quietly outearning human catalogues on TIDAL to sample libraries wiring generative tools into their own pipelines: the tools built to do the specialist's job keep getting cheaper and, more importantly, harder to dismiss.

Ten free credits, no subscription, pricing by the minute: HyFi is built to make paying a person to master your track feel like the harder option, not the safer one.

What does this do to the people who master tracks for a living?

For a producer without a mastering budget, HyFi is straightforwardly useful: a fast, consistent, professionally-engineered pass for less than the price of a coffee, with room to reprocess without opening a new invoice. But that same convenience is exactly what makes it a problem for independent mastering engineers, who have already spent years competing with LANDR, eMastered and similar services. HyFi raises the bar because it doesn't read as a shortcut, it reads as the same DSP an established, respected engineer built for his own plugin, priced low enough that skipping the human pass barely registers as a decision at all.
