Patent ID: 7672743

Claim:
A method for generating a digital audio signal from one or more digital audio samples, the method comprising: receiving a digital audio frame containing a number of the digital audio samples at a computing device comprising a processing unit; determining the number of digital audio samples in the digital audio frame; and generating the digital audio signal as one or more digital audio bursts containing the digital audio frame, at least one of the digital audio bursts comprising a burst payload and a preamble element specifying a data type and a data subtype, wherein: the data subtype specified by the preamble element indicates the number of digital audio samples in the digital audio frame, the preamble element supports a plurality of data subtypes and a plurality of sampling frequencies, the plurality of data subtypes includes at least one data subtype that supports spanning a digital audio frame sampled at a given sampling frequency across multiple digital audio bursts and at least one other data subtype that supports incorporating the digital audio frame sampled at the given sampling frequency into one digital audio burst, and the data subtype that supports spanning the digital audio frame indicates the number of digital audio samples distributed by the multiple digital audio bursts.
