Somebody questioned the quality of an MP3 audio file; he said that “…is MP3 format good in sound quality than the other audio formats?” I answered him “I know you know.” Because he knows what MP3 means.
As we all know, MPEG-1 Audio Layer 3 is a compressed sound format, for that meaning MP3 has not good enough sound quality. Why? Because it is a compression format so that the sound waves are limited to their position or for short it is not flexible unlike the other audio file formats that can feature much higher than MP3 can. Therefore, MP3 is not really good in quality, it is could just stored in a small bytes sound mediums.
