Abstract
Example methods disclosed herein to monitor media presented by a media device include adjusting, with a circuit, an inbound audio signal input to the media device based on (i) a level of an outbound audio signal generated by the media device and (ii) a level of the inbound audio signal to produce an adjusted inbound audio signal. Such disclosed example methods also include combining, with the circuit, the adjusted inbound audio signal with a sampled version of the outbound audio signal to determine a return signal. Such disclosed example methods further include processing the return signal to determine first identification information to identify first presented media having an audio portion corresponding to the outbound audio signal generated by the media device.
