quantization levels on the quality of digitized sound. The sampling rate standard for audio CD is 44,100 samples per second so the highest frequency that can be sampled without aliasing, 22,050 Hz, is above the audible range of frequencies. Also, the standard of 16-bit quantization yields quantization noise below the threshold of hearing.
High bitrate audio is overkill: CD quality is still great ...

Using the Nyquist-Shannon sampling theorem, we know that a sample rate that provides two samples per period is sufficient to reproduce a signal (in this case, your music). 2 x 22,000 = 44,000, or just under the 44,100 samples per second offered by a 44.1kHz sample rate.Anything above that number is not going to offer you much improvement because you …

When comparing bitrate, or the amount of data transferred per second, High-Resolution Audio’s bitrate (9,216 kbps) is nearly seven times higher than that of CDs (1,411 kbps) and almost 29 times higher than that of MP3s (320 kbps). And the higher the bitrate, the more accurately the signal is measured. Bitrate has a direct impact on sound quality.

The reason that the quantization errors are worse are (1) the resolution of a 16 bit file is only 1/256 that of a 24 bit file, and (2) the noise will dither ...
Explanation of 44.1 kHz CD sampling rate - Columbia University
https://www.cs.columbia.edu/~hgs/audio/44.1.html
It has been claimed that thier sampling rate differs from that of CDs to make digital copying from one to the other more difficult. 48 kHz is, in principle, a better rate since it is a multiple of the other standard sampling rates, namely 8 and 16 kHz for telephone-quality audio. Sampling rate conversion is simplified if rates are integer ...
Audio quality: Understanding bits, sample rate and formats
https://blog.hotmart.com/en/audio-quality/
It’s through the compression rate value (or bitrate) that we can control the file size and consequently, audio quality. For example, a 320 kbps MP3 (kilobits per second) can sound as good as an uncompressed CD or DVD audio. As the bitrate value lowers, the file becomes smaller, but audio loss becomes perceptible, depending on the audio in ...

Other audio sample rates: 48 kHz, 88.2 kHz, 96 kHz, etc. While 44.1 kHz is an acceptable audio sample rate for consumer audio, there are instances in which higher sample rates are used. Some were introduced during the early days of digital audio when powerful anti-aliasing filters were expensive. Moving the Nyquist frequency even higher allows ...

CD quality audio is the most widely accepted standard for high-quality audio. WAV and AIFF files offer excellent sound quality. While 320kbps MP3s provide good quality audio it will always be outdone by CD quality audio. Where MP3s shine is in file size. MP3s can reduce file sizes of CD audio files by up to 10 times if using 128kbps compression.

Low bit rates refer to smaller file size and less bandwidth with a drop in audio quality. For good quality music usually 64-128kbps (96kbps+ recommended) bit rate is preferred. Sample Rate is the number of samples per unit time. A sample is a measurement of signal amplitude and it contains the information of the amplitude value of the signal ...

A higher sample rate will give you a more precise capture of the original audio signal. In a typical digital audio CD recording, the sampling rate is 44,100 or 44.1kHz. If you’re wondering why the frequency is so high when the human ear can only hear frequencies up to 20kHz at best. It’s because of the Nyquist-Shannon sampling theorem.
