Can Unified audit trail be written to file automatically?

Hi!

We have a external tool (QRadar) that should "consume" our unified audit trails. But, they (QRadar people) want to read this from a file and I can't find anything in the documentation about settings that changes unified audit trail to be written to a file instead of to a table (or both).

We have a number of unified audit policies that needs to be written to file for QRadar and I would prefer to have it done in a Oracle automatic way instead of creating our own solution for this since that in it self will jeopardize the security.
