is mpeg audio file the same as mp3
MP3 MPEG-1 or MPEG-2 Audio Layer III,[4] more commonly referred to as MP3 (or mp3), is an audio coding format for digital audio. It uses a form of lossy data compression to encode data using inexact approximations and partial data discarding to reduce file sizes, typically by a factor of 10, in comparison with a CD while retaining a sound quality comparable to uncompressed audio. Compared to CD quality digital audio, MP3 compression commonly achieves 75 to 95% reduction in size. MP3 files are thus 1/4 to 1/20 the size of the original digital audio stream. This is important for both transmission and storage concerns. The basis for such comparison is the CD digital audio format which requires 1411.2 kbit/s. A commonly used MP3 encoding setting is CBR 128 kbit/s resulting in file of 1/11 (=9%) of the size of the original CD-quality file, that is with 91% compression.[8]
Extended play An extended play record, often referred to as an EP, is a musical recording that contains more tracks than a single, but is usually unqualified as an album or LP.[1][2][3] EPs generally contain a minimum of four tracks and maximum of six tracks,[4] and are considered "less expensive and time-consuming" for an artist to produce than an album.[3] An EP originally referred to specific types of vinyl records other than 78 rpm standard play (SP) and LP,[5] but it is now applied to mid-length CDs and downloads as well.
