// 3.2.8 Object: Audio
//
// 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.
