Abstract
According to the present invention, a method of recording and playing compact disk (CD) quality sound signals for a doorbell system is taught. Wave-formatted sound signals are first sourced either from websites or musical instrument generated files or recordings. These sound files are edited into 16 KHz/16 bits or higher resolutions. Optionally, 16 KHz/16 bits or higher sound signals can be tuned with echo effect. Optionally, sound signals are separated into specific segments. Next, the 16 KHz/16 bits or higher tunes are converted into 16 KHz/12 bits or higher binary data. The 16 KHz/12 bits or higher sound signals are embodied into a voice-based microprocessor (1.11). Finally, the 12 bits binary data are played as analog sound signals with the assistance of a built-in digital-to-analog converter (DAC) (1.10) in the microprocessor (1.11). A receiver of a doorbell system embodying the above stated method is also disclosed. The doorbell system can be a wireless or a wired version.
