Audio and artwork specifications

Audio: WAV or FLAC, at least 16-bit/44.1 kHz, stereo. After upload, files are inspected on the server (duration, sample rate, channels) and only then selected as the active version.

Artwork: square, at least 3000×3000 pixels, JPG or PNG, RGB, without URLs, prices or misleading logos.

A replacement file creates a new version; an older upload that finishes later can no longer overwrite your current choice.

If a file is rejected, the reason is shown with the upload (for example mono, sample rate too low or non-square artwork). Upload a corrected file; you don't need to create the release again.
