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 11):
An apparatus for generating a hybrid radio signal for broadcast, the apparatus comprising:\n digital input port configured to receive a digital audio sample stream; an analog input port configured to receive an analog audio sample stream; processing circuitry configured to:\n determine offsets in time between the analog audio sample stream and the digital audio sample stream using a normalized cross-correlation of audio envelopes of the analog audio sample stream and the digital audio sample stream; \n filter the determined offsets in time to produce filtered offset values; \n determine an alignment slip adjustment value as a function of the filtered offset values; \n align the analog audio sample stream and the digital audio sample stream using the determined alignment slip adjustment value; and \n generate a hybrid radio signal for broadcast that includes time-aligned analog audio and digital audio.
