The AC3 codec was designed to compress audio data while maintaining a high level of quality. By reducing the amount of data required to store audio, AC3 enabled multiple channels of audio to be stored on a single CD. This was a significant breakthrough, as previous audio codecs could only manage a single channel of audio.
