receiving, at a client device, a plurality of audio fingerprints that correspond to a plurality of media content items based on scheduled broadcast times;
storing the plurality of audio fingerprints in a memory of the client device;
detecting ambient sound using an audio input device of the client device;
generating an audio fingerprint from the detected ambient sound;
comparing, at the client device, the audio fingerprint generated from the detected ambient sound to the plurality of audio fingerprints stored in the memory of the client device; and
determining whether to transmit a received input to initiate a query to a server, wherein determining whether to transmit the received input to initiate a query to the server is based on whether the comparing indicates that the audio fingerprint matches one of the plurality of audio fingerprints stored in the memory of the client device.
