Detailed explanation-1: -In general, a high bitrate means high-quality audio, provided the sample rate and bit depth are also high. More information, in a very general sense, means better sound quality. Audio CD bitrate is always 1, 411 kilobits per second (Kbps).
Detailed explanation-2: -As the term implies, the speed in bps is equal to the number of bits transmitted or received each second. Bits per second are a unit of measurement within the larger bit rate, otherwise known as bitrate or as a variable R, which is the number of bits processed per unit of time.
Detailed explanation-3: -A 16-bit digital audio has a maximum dynamic range of 96dB while a 24-bit depth will give us a maximum of 144dB. CD quality audio is recorded at 16-bit depth because, in general, we only want to deal with sound that’s loud enough for us to hear but, at the same time, not loud enough to damage equipment or eardrums.
