24 bytes
- The data in a CD are arranged in frames. A frame comprises 33 bytes, of which 24 bytes are audio or user data, eight bytes are error correction (CIRC -generated), and one byte is for subcode.

An audio CD sector corresponds to 2,352 bytes of decoded data. The Red Book does not refer to sectors, nor does it distinguish the corresponding sections of the disc's data stream except as "frames" in the MSF addressing scheme. The following table shows the relation between tracks, timecode frames (sectors) and channel-data frames:
This audio file size calculator will help you estimate how much space an uncompressed audio file will take up. You will also learn about audio bit depth, sample rate, and more stuff about digital audio.
The audio bit rate for a Red Book audio CD is 1,411,200 bits per second (1,411 kbit/s) or 176,400 bytes per second; 2 channels × 44,100 samples per second per channel × 16 bits per sample. Audio data coming in from a CD is contained in sectors, each sector being 2,352 bytes, and with 75 sectors containing 1 second of audio.
Aug 20, 2006 · Let’s look at the two different formats first. Audio CDs are designed for one purpose: audio. They contain raw, uncompressed data, in a very fixed format: 44,000 samples per second, with each sample consisting of a 16-bit (2-byte) number for each of the right and left channels.
Dec 3, 2014 · Audio CDs do not have a filesystem, that is why explorer will not show the tracks. Instead you should install a music cd ripper, like CDex ( http://sourceforge.net/projects/cdexos/ ) which can display the size of the audio tracks.
By far, the most common is 120 millimetres (4.7 in) in diameter, with a 74-, 80, 90, or 99-minute audio capacity and a 650, 700, 800, or 870 MiB (737,280,000-byte) data capacity. Discs are 1.2 millimetres (0.047 in) thick, with a 15 millimetres (0.59 in) center hole.
Oct 6, 2024 · The standard CD can hold up to 80 minutes of audio data, which translates to approximately 20 to 25 tracks, assuming an average song length of 3.5 minutes. However, this number can change depending on the compression techniques used and the bitrate of the audio files.
