1. An apparatus comprising:
memory;
instructions; and
at least one processor to execute the instructions to at least:
process, based on a device state of a media presentation device monitored by a metering device, data from the metering device,
the device state determined by comparing i) a comparison vector representing a captured audio signal to ii) a reference vector to determine a similarity value, the similarity value indicating that the device state of the media presentation device is on when the similarity value satisfies a threshold;
when the device state is determined to be on, log media exposure based on analysis of the data from the metering device; and
output the log of media exposure.
