and the number representing each chapter is called the chapter number.
Track
Song segments programmed in a CD are called tracks (representing 1 song). The number representing each
track is called the track number.

This is the digital compression technology for sound developed by Dolby Laboratories. This technology provides
5.1 channel surround sound (front-center, front-left, front-right, left surround, right surround and low frequency
effect for woofers). Connecting a device with built-in Dolby Digital decoder will create a truly realistic sound
