Example methods disclosed herein include reusing first frequency values of audio sensed with a microphone to determine a first frequency response of the sensed audio, the first frequency values having been determined to perform watermark detection during a first monitoring time interval. Disclosed example methods also include comparing the first frequency response to a reference frequency response to determine whether the media device was active during the first monitoring time interval."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Determining media device activation based on frequency response analysis","description":"Methods, apparatus, systems and articles of manufacture (e.g., physical storage media) to determine media device activation based on frequency response analysis are disclosed.
