Methods and systems for temporally aligning audio samples of a digital portion of a radio broadcast signal with audio samples of an analog portion of the radio broadcast signal are disclosed. The methods and systems comprise the steps of receiving a radio broadcast signal having an analog portion and a digital portion; separating the analog portion of the radio broadcast signal from the digital portion of the radio broadcast signal; producing a first plurality of audio samples representative of the analog portion of the radio broadcast signal; retrieving from a memory a stored first time interval corresponding to an approximate time for data representing a first sample of the digital portion to travel through a digital signal path in a receiver, wherein the digital signal path includes a digital demodulator; measuring a second time for data representing the first sample of the digital portion to travel from an input of the digital signal path to an input of the digital demodulator; generating a delay amount for delaying a second plurality of audio samples relative to the first plurality of audio samples such that the second plurality of audio samples is temporally aligned with the first plurality of audio samples by adding the first time to the second time; producing the second plurality of audio samples representative of the digital portion of the radio broadcast signal; delaying the second plurality of audio samples by the delay amount such that the second plurality of audio samples is temporally aligned to within a predetermined amount with the first plurality of audio samples; and digitally combining the first plurality of audio samples with the second plurality of audio samples to produce a combined audio output.
