Abstract
Example methods, apparatus and articles of manufacture (i.e., physical storage media) to perform media source detection based on frequency band selection and processing are disclosed. Example metering methods disclosed herein include comparing frequency band values of a first audio signal with corresponding frequency band values of a second audio signal for a first subset of a set of frequency bands to determine a first comparison result. Disclosed example metering methods also include comparing the frequency band values of the first audio signal with corresponding frequency band values of a third audio signal for a different second subset of the set of frequency bands to determine a second comparison result. Disclosed example metering methods further include determining a source of the first audio signal based on the first comparison result and the second comparison result.
