MP2 is an extension of compressed MPEG Layer II audio files. This type of file is still the standard format for digital television and radio. However, most users prefer the MP3 format. The MP2 file is compatible with most portable audio players. We emphasize that for certain devices it is necessary to convert MP2 files to MP3 format. Note that MP2 files are not identical to MPEG-2 video files. Typically, an MPEG-2 video file is used as an MPG extension. In some cases, MP2 files are called musicam files, which cannot be considered correct. In the 80s of the last century, specialists developed many versions of MP files. It was then that the developers of the International Standardization Organization Moving Picture Experts Group (MPEG) were engaged in new standards for digital encoding of audio and video data. Part of the initial release of the MP1 files were 3 separate layers of the audio file. In the 90s, they developed the MP2 format. To this day, this format is used for digital television and radio broadcasting. Due to its broad support for MPEG-1, MP2 files can be played, saved, converted and edited by a multitude of multimedia players and audio editors on a wide variety of platforms and operating systems.
FLAC is a free cross-platform audio codec format created in 2001 by Josh Colson and Xiph.Org. The name of the format is an abbreviation of the English phrase Free Lossless Audio Codec. When compressing a file into the FLAC format, it is 50-60% of the original file without loss of sound quality (especially when working with voice recordings). When unpacking such a file, absolute originality is respected. Since the format is free and open, it is supported by almost any software, it is perfect for archiving files and for regular listening to digital recordings.
