1. A system for searching stored audio data, the system comprising:
- a memory configured to store audio data comprising a plurality of audio frequency distributions received over a plurality of broadcast channels from a radio receiver;
an input device configured to receive a search pattern comprising at least one frequency distribution in aural content from a vehicle occupant; and
a processing circuit in communication with the memory and the input device, the processing circuit configured to receive the search pattern, to search the stored audio data for the search pattern by comparing the at least one frequency distribution in the aural content from the vehicle occupant with multiple characteristics of the stored audio data comprising the audio frequency distributions, wherein the processing circuit is further configured to provide, to an output circuit, audio data from the stored audio data that correlates to the search pattern, and wherein the comparison comprises;
a first correlation test in which a first function of the search pattern is compared to a first function of the stored audio data, anda second correlation test in which a second function of the search pattern is compared to a second function of the stored audio data,wherein the first function and the second function are different functions.

14. A method of searching stored audio data received over a plurality of broadcast channels at a radio receiver of a vehicle radio, the method comprising:
-
receiving a search pattern comprising at least one frequency distribution in aural content from a vehicle occupant; searching stored audio data comprising audio frequency distributions, received over the plurality of broadcast channels from the radio receiver, for the search pattern; comparing multiple characteristics of the at least one frequency distribution of the search pattern with the frequency distributions of the stored audio data using a processor; and providing, to an output circuit, audio data from the stored audio data that correlates to the search pattern, wherein comparing comprises; a first correlation test in which a first function of the search pattern is compared to a first function of the stored audio data, and a second correlation test in which a second function of the search pattern is compared to a second function of the stored audio data, wherein the first function and the second function are different functions. - View Dependent Claims (15, 16, 17, 18, 19, 20)
