Abstract
Provided are a method of generating and playing an object-based audio content that may effectively store preset information about an object-based audio content, and a computer-readable recording medium for storing data having a file format structure for an object-based audio service. The method of generating the object-based audio content may include: receiving a plurality of audio objects (310) generating at least one preset using the plurality of audio objects (320) and storing a preset parameter with respect to an attribute of the at least preset and the plurality of audio objects (330). The preset parameter may be stored in a form of a box that is defined in a media file format about the object-based audio content. Through this, it is possible to effectively store a preset about a plurality of audio objects.
