Apparatus for ability practice song using MP3 file and method

The present invention relates to an apparatus and method for providing a song practice function using an MP3 file. Generally, a song using an MP3 file that allows a user to be provided with a song practice function using an MP3 file used for listening to music. An apparatus and method for providing a practice function are provided.

First, let's take a moment to look at MP3 (Moving Picture Experts Group (MPEG) -1 Audio Layer 3: hereinafter referred to as 'MP3').

MP3 is an audio data compression technology that is part of the functional specifications of MPEG-1 and MPEG-2. The size of music files stored on compact disks (hereinafter referred to as 'CD') is about 30-50 MB. However, MP3 technology can reduce data capacity to less than about one-twelfth of the original, while maintaining sound quality at about the same level.

The reduced file size is only 2 ~ 5 MB per song, which makes it easy to send and receive high quality music through the network.

At present, personal computers (hereinafter referred to as 'PC') are easily seen in communication or the Internet, which are made of MP3 files, and are becoming a popular item among netizens.

In line with this trend, MP3 homepages that provide hundreds of thousands of music files have appeared all over the world these days, and if you use these MP3 files, you can pick and listen to the songs you want without having to buy a record. You can appreciate it.
