Abstract:
A method for processing audio signals in a radio transmitter, includes: receiving an analog audio sample stream and a digital audio sample stream; determining offsets in time between the analog audio stream and the digital audio stream using a normalized cross-correlation of audio envelopes of the analog audio sample stream and the digital audio sample stream; filtering the determined offsets in time to produce filtered offset values; determining an alignment slip adjustment value as a function of the filtered offset values; aligning the analog audio sample stream and the digital audio sample stream using the determined alignment slip adjustment value; and generating a hybrid radio signal for broadcast that includes time-aligned analog audio and digital audio.

Claim (Index 13):
The apparatus of  claim 11 , including a slip buffer configured to offset one of the analog audio sample stream or the digital audio sample stream with respect to the other of the analog audio sample stream or the digital audio sample stream using the determined alignment slip adjustment value, and change the offset using hysteresis according to a slip value determined as a difference between a filtered offset value and an ideal offset value.
