Audio compact disc.
An audio CD is a compact disc containing music or audio tracks. The audio data is stored in pulse-code modulation (PCM) format with a sample rate of 44.1 kHz, which equates to approximately 10Mb per minute. This is roughly 10 times the size (and quality) of a standard 128kbps MP3 file.
