Methods, apparatus, and machine-readable storage media to monitor a media presentation

An apparatus, comprising:

• at least one memory;
• instructions;
• and
• processor circuitry to execute the instructions to:
• compare a location of the apparatus with a set of reference locations at which audio monitoring is to be performed;
• request a status message from a media presentation status server, the status message to indicate whether a likelihood of media being presented at a first location of the set of reference locations satisfies a threshold, the processor circuitry is to request the status message when the location of the apparatus corresponds to the first location of the set of reference locations, the processor circuitry is not to request the status message when the location of the apparatus does not correspond to any of the set of reference locations, the media presentation status server separate from the apparatus;
• and
• enable a microphone to collect audio when the status message indicates that the likelihood of media being presented at the first location of the set of reference locations satisfies the threshold, the processor circuitry is not to enable the microphone to collect audio when (1) the status message indicates that the likelihood of media being presented at the first location of the set of reference locations does not satisfy the threshold, or (2) the location of the apparatus does not correspond to any of the set of reference locations.

An apparatus comprising:

• at least one memory;
• instructions;
• and
• processor circuitry to execute the instructions to:
• compare a location of a mobile device with a set of reference locations at which audio monitoring is to be performed;
• enable a microphone of the mobile device to collect audio for media monitoring in response to:
• (1) determining that the location of the mobile device corresponds to a first location of the set of reference locations;
• and (2) monitoring a media presentation at the first location of the set of reference locations and determining that a likelihood of the media presentation at the first location satisfies a threshold;
• disable the microphone from collecting audio for media monitoring when the location of the mobile device corresponds to the first location and the the likelihood of the media presentation at the first location does not satisfy the threshold;
• and
• disable the microphone from collecting audio for media monitoring when the location of the mobile device does not correspond to any of the set of reference locations.
