- 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. If you do the math, that’s 176,000 bytes per second, or 633,600,000 bytes for an entire hour of audio.

If you’ve ever seen blank, 70-minute CDs, these hold roughly 740 megabytes of data – enough for about 70 minutes of sound in audio CD format. Data CDs, on the other hand, hold anything.
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 ...
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.
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.
May 27, 2013 · The bitrate is the number of bits per second. bitrate = bitsPerSample * samplesPerSecond * channels. So in this case for stereo the bitrate is 8 * 44100 * 2 = 705,600kbps. To get the file size, multiply the bitrate by the duration (in seconds), and divide by 8 (to get from bits to bytes):
Jul 23, 2015 · Generally speaking for PCM samples you can divide the total length (in bytes) by the duration (in seconds) to get the number of bytes per second (for WAV files there will be some inaccuracy to account for the header). How these translate into samples depends on. the sample rate; bits used per sample, i.e. commonly used is 16 bits = 2 bytes
