It is like a wav file for the Macau – the standard audio file format used by Sun, Unix and Java. The audio in au files can be PCM or compressed with the μ-law, a-law or G729 codecs. midi - an industry-standard protocol that enables electronic musical instruments, computers, and other equipment to communicate, control, and synchronize with each othermp3 – MPEG Layer-3 format is the most popular format for downloading and storing music. By eliminating portions of the audio file that are essentially inaudible, mp3 files are compressed to roughly one-tenth the size of an
