Visitors can speak into a Microphone and see their voice in both Analog and Digital Formats in the two Screens. They can also play a list of Audio Samples to explore their difference in the two Formats.
Visitors can experiment with Sounds, which are stored in different Audio Formats. Visitors can see the Waveform and the Frequency Spectrum of the Sounds, and apply some Special Effects to them by Digital Audio Processing.
Visitors can listen to different Audio Signals in High Quality or in Telephone Quality. Visitors can observe the Waveform and the Spectrum of the Audio Signals and they will see that although the Waveforms look similar, the Spectrums show clearly the difference of Audio Signals between the High Quality and the Telephone Quality.
