Detailed explanation-1: -MP3. MP3 (MPEG-1 Audio Layer III) is the most popular of the lossy formats. MP3 files work on most devices, and the files can be as small as one-tenth the size of lossless files.
Detailed explanation-2: -But what makes MP3 so attractive to music fans? MP3’s offer CD-quality sound and can be stored easily-an average song often takes anywhere from 3 to 5 megabytes of space.
Detailed explanation-3: -The highest quality MP3 bitrate is 320 kbps at 16 bit. You can encode MP3s as low as 96 kbps. MP3s use a compression codec that removes frequencies while trying to preserve as much of the original recording as possible.
Detailed explanation-4: -What is the best audio format for sound quality? The best audio formats for sound quality are uncompressed or lossless compression files-think WAV, FLAC, and M4A. That’s because these formats retain the original sound quality, though you’ll have to put up with the fact these files will be large.
