-SYS user.
-DELETE ANY TABLE system privilege. （If O7_DICTIONARY_ACCESSIBILITY=TRUE）
-A user to whom SYS has granted the object privilege DELETE on SYS.AUD$ table.

2）Before deleting any rows you may want to archive the table. You can achive this by creating a table from SYS.AUD$ and export that. Don"t export SYS.AUD$ directly.
SQL>CREATE TABLE AUDIT_RECORD TABLESPACE users as select * from SYS.AUD$;
Now export the table as,
SQL> host exp tables=AUDIT_RECORD file=audit_record.dmp

3）To delete all records from audit trail table SYS.AUD$ issue,
SQL>DELETE FROM SYS.AUD$;

To delete all records of particular audited table from the audit trail issue,
SQL>DELETE FROM sys.aud$ WHERE obj$name="&table_nmae";

But deleting in this way will not reduce size on the system tablespace or aud$ table. In order to reduce size follow section 4.

4）Truncate audit table to reduce size.
