    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.

    Abstract: An ancillary code is extracted from the media signal by monitoring the media signal during a first time interval according to a first monitoring parameter, evaluating the media signal to detect an ancillary code and optionally monitoring the media signal during a second monitoring time interval depending on an outcome of the evaluation of the media signal. In different iterations, different data acquisition window durations and/or overlaps are applied according to a factor such as an iteration count or a detection confidence level.
