Digital vs. Analog Audio Signals Recording Media
|
Introduction |
| To
store sounds in computers, we have to convert analog sounds into digital
representations of the sound. To change continuous analog sound into
discrete digital format requires a three-step process.
First, the
analog signal has to be sampled [electronic slicing] at an appropriate
rate. Next we need to decide how precisely we need to represent
the samples. In the other words, we need to decide how many bits
to use to represent each sample? Finally, we have to select a coding
system and decide how to use extra or redundant bits to detect and
correct errors. |
