Audio checks

Read your tempo and key, shape playback with an EQ, check mono, and get notes on your mix.

Aden listens to every version you upload and gives you tools to hear it better. Most checks run in your browser, so nothing extra is uploaded.

To hear two versions side by side, see Compare versions.
