Sampling Theory For Digital Audio By Dan Lavry, Lavry Engineering, Inc. Credit: Dr. Nyquist discovered the sampling theorem, one of technology’s fundamental building blocks. Dr. Nyquist received a PhD in Physics from Yale University. He discovered his sampling theory while working for Bell Labs, and was highly respected by Claude Shannon,
Sampling Theory - Stanford University

Sampling Theory. Nowadays, audio processing is typically carried out in discrete time. As a result, sampling theory is fundamental to digital audio signal processing. The sampling theorem is credited to Harold Nyquist (1928), extending an earlier result by Cauchy (1831) based on series expansions. Claude Shannon is credited with reviving interest in the sampling …

Sampling theory, the best explanation you’ve ever heard—Part 1. I’ll start by giving away secrets first: Individual digital samples are impulses. Not bandlimited impulses, ideal ones. We know what lies between samples—virtual zero …
Digital Audio Basics: Audio Sample Rate and Bit Depth
https://www.izotope.com/en/learn/digital-audio-basics-sample-rate-and-bit-depth.html
The audio sample rate determines the range of frequencies captured in digital audio. In most DAWs, you’ll find an adjustable sample rate in your audio preferences. This controls the sample rate for audio in your project. The options you see in the average DAW—44.1 kHz, 48 kHz—may seem a bit random, but they aren’t!
Synthesis Chapter Five: Digital Audio Overview
https://cmtext.indiana.edu/digital_audio/chapter5_overview.php
The principles which underlie almost all digital audio applications and devices, be they digital synthesis, sampling, digital recording, or CD or cell phone playback, are based on the basic concepts presented in this chapter. New forms of playback, file formats, compression, and storage of data are all changing on a seemingly daily basis, but the underlying mechanisms for …
Theory of Upsampled Digital Audio - MLSSA

Theory of Upsampled Digital Audio 2 of 6 Copyright 2002 by Douglas D. Rife For perfect waveform reproduction, sampling theory requires that the digital reconstruction filter remove all frequency components above the Nyquist frequency or ½ the sampling rate of the input digital data. Because CDs encode audio data sampled at
Digital Audio 101: The Basics — Pro Audio Files
https://theproaudiofiles.com/digital-audio-101-the-basics/
The Nyquist rate is a concept derived from digital sampling theory which states that to accurately represent a particular frequency, the signal must be sampled at twice the rate of that frequency. For example, to create an accurate digital representation of 10 kHz, you would need to use a minimum 20 kHz sampling rate.

Let’s start with the Shannon Sampling Theory, the basis for digital audio: “If a function of time f(t) contains no frequencies higher than W Hertz, it is completely determined by giving the value of the function at a series of points spaced 1/2W seconds apart.”
Nyquist Sampling Theorem - Department of Music
http://musicweb.ucsd.edu/~trsmyth/digitalAudio171/Nyquist_Sampling_Theorem.html
The Nyquist Sampling Theorem states that: A bandlimited continuous-time signal can be sampled and perfectly reconstructed from its samples if the waveform is sampled over twice as fast as it's highest frequency component. Nyquist limit: the highest frequency component that can be accurately represented: Nyquist frequency: sampling rate required to accurately represent up to :
