- The CD-ROM data unit is called block. A CD-ROM block consists of 2352 audio bytes of a CD-DA block. Of the 2352 bytes of a block, 2048 bytes (computer data) or 2336 bytes (audio data) are available for user data.

The smallest entity in a CD is a channel-data frame, which consists of 33 bytes and contains six complete 16-bit stereo samples: 24 bytes for the audio (two bytes × two channels × six samples = 24 bytes), eight CIRC error-correction bytes, and one subcode byte. As described in the "Data encoding" section, after the EFM modulation the number ...
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.
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.
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.
Every sector on every type of CD contains 3234 bytes of data, 882 bytes of which are reserved for error detection and correction code and control bytes, leaving 2352 bytes (3234 minus 882) to hold audio data in a Red Book CD‑Audio disc.
Feb 13, 2016 · Each audio sample in turn has 16 bits of resolution, or two bytes. If we multiply 44.1 KHz (the sampling rate) by two (number of channels), and then by 16 (bits of resolution), we get the data rate of CD in bits per second.
We need to figure out how much storage we need. Let’s assume we’re working with a stereo (two independent channels of sound) signal and 16-bit samples. We’ll use a sampling rate of 44,100 times/second. One 16-bit sample takes 2 bytes of storage space (remember that 8 bits equal 1 byte).
