Acoustic Exchange defines an audience as a collection of IDs that describe a group of individuals that marketers can target with products, services, or other marketing treatments. The IDs can be associated with various descriptive attributes that business users can use to better define the audience and target their marketing efforts.

Typically, the audience is generated by segmenting one or more customer databases according to various business rules and selection logic. Acoustic Exchange provides a means to share the IDs and attributes between Acoustic Exchange endpoints as a bulk exchange of data.

When Acoustic Exchange users share data between endpoint applications, Acoustic Exchange provides a way to map identifier and attribute names between the two applications.
