Disable audit object on oracle 11

How can I disable audit objects on Oracle 11? I have tried

NOAUDIT ALL;
NOAUDIT NETWORK;
NOAUDIT SESSION;
NOAUDIT ALL ON DEFAULT;
NOAUDIT SELECT INSERT UPDATE DELETE EXECUTE PROCEDURE;
NOAUDIT PRIVILEGES;




But audit still generate, grows fast and, of course, my db becomes full.



When I query sys.aud, audit objects like insert, delete, update are being logged to sys.aud.



If someone has solution to this problem, please help me.
