1. A method to monitor presentation of media, the method comprising:
- determining, with a processor, first frequency-domain data from time-domain audio data corresponding to the media, the first frequency-domain data including first frequency band values associated with respective first frequency bands;
combining, with the processor, respective ones of the first frequency band values associated with contiguous groups of the first frequency bands to determine second frequency-domain data including second frequency band values associated with respective second frequency bands;
processing, with the processor, the first frequency-domain data to obtain a code included in an audio portion of the media; and
processing, with the processor, the second frequency-domain data to obtain a signature representative of the audio portion of the media.

Abstract
Methods and systems are provided for gathering research data that includes information pertaining to audio signals received on a portable device, such as a cell phone. Frequency domain data is received or produced, a signature is extracted from the frequency domain data and an ancillary code is read from the frequency domain data.

8. A tangible machine readable storage device or storage disk comprising machine readable instructions which, when executed, cause a machine to at least:
-
determine first frequency-domain data from time-domain audio data corresponding to a presentation of media, the first frequency-domain data including first frequency band values associated with respective first frequency bands; combine respective ones of the first frequency band values associated with contiguous groups of the first frequency bands to determine second frequency-domain data including second frequency band values associated with respective second frequency bands; process the first frequency-domain data to obtain a code included in an audio portion of the media; and process the second frequency-domain data to obtain a signature representative of the audio portion of the media. - View Dependent Claims (9, 10, 11, 12, 13, 14)
