Time zone equalizer

An audio selection circuit having time selectable equalization, comprising:

• an input for coupling said audio selection circuit to an audio signal source;
• a variable equalization circuit coupled to said input and having an equalization output, said variable equalization circuit providing variable attenuation in a plurality of frequency bands to an audio signal coupled to said input;
• a processing means operatively coupled to said input and to said variable equalization circuit;
• a memory means operatively coupled to said processing means;
• wherein said memory means stores data, said data consisting essentially of a sequence of equalization profiles and an activating time of day, and
• a timebase means operatively coupled to said processing means, said timebase means enabling said processing means to determine a time of day;
• wherein said memory means is indexed by time of day;
• wherein said processing means varies the equalization of said audio signal with each of said sequence of equalization profiles when said time of day is equal to a predetermined time of day.

A method of time selectable equalization of an audio signal, comprising the steps of:

• (a) providing an input for coupling to an audio signal source;
• (b) providing a variable equalization circuit having an equalization input and an equalization output, said variable equalization circuit providing variable attenuation in a plurality of frequency bands to an audio signal coupled to said equalization input;
• (c) inputting a data set into a memory, said data set consisting essentially of an equalization profile and an activating time of day;
• (d) determining an actual time of day;
• (e) indexing said memory to retrieve said equalization profile when said actual time of day is equal to or past a predetermined time of day.
