Music need good mp3 player

Loving music is nature of human; there are many miracles about music and human. Help some one to recover, decrease crime. There are people who enjoy music while jogging, cycling, driving and working out, so why not while doing your laps or playing in the water? Just make sure you don't doze off in the middle of the pool. Now music needs mp3 players.

An MP3 is a digital audio file compressed with a standard defined by the Motion Pictures Experts Group. MPEG was formed to develop techniques for dealing with digital video; since most video also contains audio, MP3 was developed as an audio extension of that work. Officially known as "MPEG-1, Layer 3", MP3 player is a lossy compression algorithm that uses psychoacoustic modeling to reduce the size of audio files by up to 90%.

Psychoacoustics takes advantage of deficiencies in the human hearing system to throw away digital bits corresponding to sounds that cannot be heard. The human ear cannot hear soft sounds in the presence of loud sounds having a similar frequency; for example, a voice conversation becomes inaudible when a jet flies low overhead. This effect is known as auditory masking, and done correctly the discarded sounds will not be missed.

There are also people who need aquatic workout for injuries and surgeries, and they may benefit from using a portable MP3 player. Besides, it can be a good choice for surfers, water skiers, and even slope skiers and snowboarders.
