Audio

Audio signals are continuous analog signals. They are first captured by a microphones and then digitised and store -- usually compressed as CD quality audio requires 16-bit sampling at 44.1 KHz (There are other audio sampling rates -- Chapter 6). So 1 Minute of Mono CD quality audio requires 60*44100*2 Bytes which is approximately 5 Mb.
