Mixing tools, judged by the curve.
13x Audio makes plugins for engineers who decide in the session, not on the sales page. The first one, AURORA, is a free 24-band dynamic EQ for Windows, macOS and Linux — the whole plugin, not a demo. Paid tools follow: sold once, updated, never a subscription.
What we hold ourselves to
Free means free
AURORA is the whole plugin with no account, no license key and no trial timer. The download button is a direct link to the file.
Built in the open
Every release is public with its date and what changed, and every build ships with its SHA-256 so you can verify the file.
Buy once, keep it
Paid plugins will be one-time purchases with updates — no subscription. Everything runs offline: VST3 · CLAP · AU · LV2 on Windows · macOS · Linux.
Try AURORA in your session.
Free, no account — download it and judge it by ear.
