Lossy Audio Formats: These are based on sound models which eliminate audio data such humans cannot or can hardly hear, for example: a low volume sound after a large volume sound. MP3 and Vorbis both are popular illustrations. lossy audio file formats is MP3 i.e. one of the most admired, that uses the MPEG-1 audio layer 3 codec to give acceptable lossy compression for music files.
