FAQ
Common questions.
Is MixMasterAI mastering really free?
Yes. You can master a compatible song and export the result without creating an account or adding a watermark.
Does AI mastering replace a mastering engineer?
It automates repeatable analysis and processing decisions. A trusted human engineer can still provide deeper artistic direction for high-budget or unusually complex releases.
What loudness should I choose?
Choose based on genre, arrangement and intended delivery—not one universal number. MixMasterAI offers practical profiles and reports true-peak safety separately from perceived loudness.
Does my song get uploaded?
The browser mastering booth processes compatible audio on your device. Your active Release Studio project is stored locally in your browser so connected tools can reopen it.
