For CDs: 44,100 samples per second, each one sampled over 16-Bit, everything over two channels (left-right stereo). It is measured in bits per second and is calculated fairly easily. This affects the precision with which the sound is reproduced: the higher the sampling rate, the more natural and precise the sound reproduction will be.īitrate, the flow of binary data, expresses the speed of information per second. For a CD, the sampling rate used is 44.1 kHz, meaning that each second of sound, when converted, is divided into 44,100 samples.
Sampling rate corresponds to the number of samples per second. For a CD, each sample has a resolution of 16-Bit its dynamic range is expressed over a range of 96 dB (decibels), with 1 bit corresponding to 6 dB. The difference in richness of sound and feeling is very substantial compared to MP3 files or even CD quality. This is also called studio quality because 24-Bit resolution is used in a recording studio. These files are encoded with 24-Bit resolution (as opposed to 16-Bit for CD quality). Hi-Res Audio is dedicated to audio files that deliver sound with a quality superior to that of a CD. On Qobuz, the CD quality files are available in FLAC, a lossless compression format which reduces the size of the files without altering their original quality. Digitally, CD quality corresponds to a specification which has a format equivalent to that of the original file: 16-Bit / 44.1kHz.

This corresponds to the sound quality similar to that of a Compact Disc which you would listen to on a CD player. The MP3 notably allows for a file size considerably smaller than that of a CD file, hence its mass use in the streaming industry.

The bit rate of 320kbps corresponds to the number of bits per second, in this instance 320,000. It is a destructive format which greatly alters the sound quality. The MP3 file is a lossy audio compression format.
