Discover what eMastered is — an AI-powered online mastering tool built with Grammy-winning engineers that polishes your tracks in minutes.

eMastered is an online audio mastering tool developed with input from Grammy-winning engineers and enhanced with AI. It’s built for musicians and creators who want a quick, straightforward way to master their tracks. Upload your audio, and the tool applies professional studio techniques — EQ, compression, and saturation — to improve sound quality. You can compare the mastered version side-by-side with your original, preview it, and download the result as WAV or MP3.
The system analyzes your uploaded audio and creates masters tailored to each song’s characteristics. Thanks to machine learning, it adapts to your style and gets smarter with every track processed. If you want more control, advanced mastering options let you manually adjust compression, EQ, stereo width, and volume.
eMastered was created by Smith Carlson, a Multi-Platinum, GRAMMY Award-winning engineer who has worked with artists including Taylor Swift, Maroon 5, Rihanna, Kanye West, Beyoncé, OneRepublic, and Ariana Grande. The platform launched on December 3, 2019, with the goal of making AI-powered reference mastering simple and affordable.
eMastered suits musicians and producers who want a professional-sounding master without the cost or turnaround time of a traditional studio session. It’s especially useful if you want to match the sonic character of reference tracks or retain hands-on control through its advanced settings.
