Audio obtained from a car radio is converted to digital data that is stored in a circular buffer, the size of which enables at least several seconds of audio to be recorded continuously. When a driver or passenger hears something of interest, data in the circular buffer is converted to strings of text. The text obtained from the recorded data is presented on a display device where individual text strings can be selected for transmission to an Internet search engine running on a computer or saved for the future use. The results of the Internet search are presented on the display device. |
