///
/// This object represents an audio type impression. Many of the fields are non-essential for
/// minimally viable transactions, but are included to offer fine control when needed. Audio in
/// OpenRTB generally assumes compliance with the DAAST standard. As such, the notion of companion
/// ads is supported by optionally including an array of Banner objects (refer to the Banner object
/// in Section 3.2.6) that define these companion ads.
///
/// The presence of a Audio as a subordinate of the Imp object indicates that this impression is
/// offered as an audio type impression. At the publisher’s discretion, that same impression may
/// also be offered as banner, video, and/or native by also including as Imp subordinates objects of
/// those types. However, any given bid for the impression must conform to one of the offered types.
