A method is provided for saving information which is provided with Audio Data but is not a part of the internal representation of this Audio Data. a. The extra information is called an Audio Descriptor (AD). b. This AD is stored away from the Audio Data, in a part of the data unit (Non-Text Object) called the Non-Text Object Signature Round Trip Area. This extra data is stored in such a way that it can be optionally used by other processes. Thus, processes which do not require this information are not penalized in any way by having to access it unnecessarily. The RFT:DCA document format, created by IBM, uses an architected arrangement of structured fields to represent AUDIO Data. This architecture is called Audio Object Content Architecture (AOCA).
