A digital audio player (DAP), more commonly referred to as an MP3 player, is a consumer electronics device that stores, organizes and plays audio files. Some DAPs are also referred to as portable media players as they have image-viewing and/or video-playing support. MP3 players are now regularly built into mobile phones, making them the most common form of digital audio player. In short, an MP3 player is a portable device that plays digital music files–although many MP3 players can do much more than that. They evolved from the portable cassette and CD players that we carried around in the 1980s and ’90s. Instead of bulky cassettes or scratch-prone compact discs, most MP3 players play files stored directly on the device. Aside from a pair of headphones, there is nothing extra you need to carry to enjoy your music collection.

An MP3 is a digital audio file compressed with a standard defined by the Motion Pictures Experts Group (MPEG). 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 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.  Read more...
