Dolby Digital is the name for data and audio compression technologies. which is the common version containing up to six discrete channels of sound
or Advance Audio Coding is a standardized, lossy compression and encoding scheme for digital audio. ( taken from wiki) after the lesson from my professor. i figured this was a good example of a lossy compression tool.
so i found this site that i dont quite understand that gives you free codecs. CHECK IT OUT!
