What is a Digital Audio Player?

What is the MP3 file?
MP3 stands for MPEG1-Layer3 and it uses a compression technology that
converts conventional CD music data into an MP3 file format that is used on a
PC, at 1/12 compression ratio. It provides CD-quality music.
What is the WMA file?
It is a multimedia compression method from Microsoft. The technology
specifically compresses music data from the “ indow Media Technologies”. As it
provides sound quality equivalent to 128Kbps using only 64Kbps format, it takes
only half as much space as MP3 file format for compressing music data.
What is a Portable Digital Audio Player?
It is a portable device that stores and plays digital audio files, which once were
only playable on a PC.
Note
1. Accessories and option products may change depending on the product
characteristics.
