Not surprisingly, the widespread popularity acquired audio compression format providing the coefficient compression of about 1:10 compared to Raw pcm at almost the same quality sound. These formats use compression algorithms to lossy audio. They can be compared with the graphic format jpg. Jpg file size is much smaller than similar bmp-file, but the image quality is somewhat worse (the more compression ratio – the worse the quality). Among the audio compression format with losses to date in the lead three: mp3, wma, and Ogg Vorbis.
