Abstract
A method for transmitting sound waves using a time-varying frequency-based symbol includes the steps of: storing waveform data in a digital form; converting the waveform data in the digital form into an analog signal; and outputting the analog signal as sound waves through a speaker. Herein, the waveform data in the digital form includes a symbol the frequency of which changes with time within a sound wave band.
