Digital Players

More commonly referred to as an MP3 player, a digital audio player ("DAP") 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. Most DAPs are powered by rechargeable batteries, some of which are not user replaceable. Listening to music stored on DAPs is typically through earphones connected with a 3.5 mm jack.

Digital audio players are generally categorized by storage media:

• Flash-based Players: These are non mechanical solid state devices that hold digital audio files on internal flash memory or removable flash media called memory cards. Due to technological advancements in flash memory, these originally low-storage devices are now available commercially ranging up to 32 GB.^[1] Because they are solid state and do not have moving parts they require less battery power and may be more resilient to hazards such as dropping or fragmentation than hard disk-based players. Basic MP3 player functions are commonly integrated into USB flash drives.
• Hard drive-based Players or Digital Jukeboxes: Devices that read digital audio files from a hard disk drive (HDD). These players have higher capacities currently ranging up to 250 GB.^[2] At typical encoding rates, this means that thousands of songs – perhaps an entire music collection – can be stored on one player.
• MP3 CD Players: Portable CD players that can decode and play MP3 audio files stored on CDs.
