Mixea by DistroKid

Mixea by DistroKid is an online mastering service that runs entirely in the browser. You drop in a track — WAV, FLAC, MP3, M4A, or AIFF — and get back a mastered version without booking an engineer or installing software. The first track is free; after that, it costs €89.99 a year for unlimited mastered tracks. The whole pitch is speed: upload, master, download, move on.

The workflow is deliberately simple. Upload a file, then choose from different EQ and Intensity options and preview the results before you commit. That hands-on part matters, because you're not locked into a single one-size-fits-all sound. Finished tracks come out as 24-bit, 48 kHz WAV files, and the output is tuned for streaming services, which removes some of the guesswork around loudness and file format. For many independent releases, that's the majority of what "mastering for streaming" actually involves.

Who is this for? Musicians who need a quick, consistent polish before release. Home recordists who want a decent master for a demo or an independent single without paying a dedicated engineer. Even experienced producers can use it to check how a rough mix might translate to streaming. Mixea by DistroKid doesn't pretend to replace the nuanced work of a skilled human ear — it's an automatic tool built for speed and convenience, and it's honest about that.
