Abstract: In one embodiment, an apparatus includes: a first demodulator to demodulate a digital signal into a first demodulated audio signal; a second demodulator to demodulate an analog signal into a second demodulated audio signal, the first and second demodulated audio signals including common content; and a delay determination circuit to determine a delay value between the common content of the two demodulated audio signals based at least in part on a first delay estimate having a first resolution and a second delay estimate having a second resolution.
