# Audience

In Acoustic Connect, each organization has one dataset (audience). Advertising agencies need a separate organization (and a separate audience) for each client.

It is not possible to delete an audience. You can restructure the audience and manage the contacts inside.

Each audience has the optional **Contact key** field and at least one **addressable field** (phone number or email address). The total number of fields is unlimited.

The audience can hold up to 2000 contact attributes.
