Original Simple Analog Waveform.
When a computer digitally samples an analog audio wave, it starts at a point in time, say zero seconds,
and reads the value of the audio at that point. Now, it moves on, to the next point in time, say one second,
and reads this value of audio. Each time the computer does this, it is “sampling” the audio waveform.
Every sample is stored on the hard drive of the SMARTCASTER:
Digital Sample of Analog Waveform.
Now, to play back the audio, the computer essentially plays that childhood game - Dot to Dot. To fill in
the gaps, it draws straight lines between each sample. Of course, when samples are done one second
apart, the digital recreation of the analog audio signal is not a very good resemblance. (See below.)
However, when the samples are done 32,000 times every second, the quality of the sound is excellent.
Digital Recreation of Analog Waveform.
Most importantly, since these digital values of the analog waveform are stored numerically, the audio
sounds exactly the same every time it is played. There is no degradation of the audio - no matter how
many times it plays over the air.
