Assignee: SIRIUS XM RADIO INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 10:
11. A non-transitory computer readable medium containing instructions that, when executed by at least one processor of a computing device, cause the computing device to:
obtain parameters for a cross-fade between N audio streams comprising compressed packets;
time align the packets from each stream that are involved in the cross-fade;
synthesize composite compressed packets containing information derived from the N streams; and
present the composite compressed packets to an audio decoder during a cross-fade phase;
wherein each stream is encoded with EAAC Plus, and said time aligning the packets is performed by estimating the time instance for an (i+l)th frame in the stream as:

t(i+1)=(i*2048*number_of_raw_data_blocks_in_frame)/sampling_frequency.
