1. An electronic audio monitor and recording apparatus, said apparatus comprising:
- self contained portable receiver means carried by an individual for detecting a coded audio signal transmitted at a frequency not detectable by the human ear by multiple television or radio broadcasts delivery at various locations;
signal processor means for converting said audio signal into a digitized signal;
means for appending a time stamp to said digitized signal;
means for storing data corresponding to said digitized signal;
a rechargeable power supplya means for coding signals for transmission in a television or radio broadcast comprising;
a computer means having an EPROM and a real-time digital clock with pre-programmed identification signals;
an audio tone generator operatively associated with said computer means for producing a series of tones for identifying a program source defined as a first tone for indicating transmittal, a second tone for indicating program type, a third tone for indicating program source, a forth tone for indicating validating said digitized signal, and a fifth tone for ending of transmittal and placing said receiver into a wait state mode in correspondence to said identification signals for placement in said program, said forth tone is compared to a algorithmic value to determine whether said third tone is a program source to be recorded; and
a means for insertion of said series of tones into a television or radio signal.
