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,
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!
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 …

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
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 …
Nyquist Sampling Theorem - University of California, San …

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 :

For digital sampling, we simply measure the height of each impulse of the PAM result, and encode it as a number. Pulse Amplitude Modulation and encoding—we call the combined process Pulse Code Modulation. Now you know what PCM means. Impulses, really
