eMastered is an online mastering engine made by Grammy-winning engineers and powered by AI. You upload an MP3, AIFF or WAV file, and it analyzes the audio, picks the processing it needs such as EQ, compression and saturation, and returns a louder, crisper master in a few seconds. You can compare the master with your original before downloading it as a WAV or MP3. A reference mode analyzes another song's sonic identity and matches loudness, balance and compression to it.
Independent artists, bedroom producers and songwriters use it to finish tracks without paying for studio mastering. Engineers and mixers can use it to preview a quick master for clients. Paid plans add Advanced Mastering Options, where users manually adjust compression, EQ, stereo width and volume and save their settings as presets, and a subscription allows unlimited masters per month. Artists who release their own music can go further with eMastered Studio, which bundles mastering with distribution, stem separation, pre-save tools, link-in-bio pages and VSTs.
Typical workflows include mastering a finished single before uploading it to streaming services, matching the loudness and tonal balance of a favorite release by uploading it as a reference, and saving a preset for an entire EP so every song gets consistent treatment. A producer might separate stems or remove vocals with the companion tools, then master the result. Users working in genres from hip hop to EDM can rely on the engine to build a custom master for each song, and unlimited distribution lets them keep all royalties on releases.
