How does it work?

If you hear a voice from that hardware, the voice of the digital data in waveform including wav and mp3 is transferred to sound card. These digital data through digital signal processing (DSP) with digital-analog converter (DAC), which the digital signal into an analog signal processing coverts. The analog signal is then amplified and output through the loudspeaker.

In the meantime, if you have the sound through a microphone, the analog sound of the DSP with analog-digital converter (ADC) processes. The analog signal is then converted into a digital signal. This signal is then stored in waveform table format in a disk or it is compressed into another format such as mp3.
