Privacy is set at the collection level. All new collections are private by default. To change the privacy of any audio item, you'll need to move the item to a collection with a different privacy setting.
To change the collection of an audio item, click the "Edit Item" and select a new collection from the Collection dropdown menu.
You may need to refresh the page in order to finalize the new privacy setting.
If you've added your audio to an Internet Archive collection and would like to have it removed, contact us at firstname.lastname@example.org.
If you are on an organization, and wondering why your "private" collection is visible to other team members, read about privacy for organization plans.
