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, 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 …

Sampling Theory • Example -- CD Audio – sampling rate of 44,100 samples/sec – ∆ = 1 sample every 2.26x10-5 seconds • Using Nyquist Theorem – CDs can accurately reproduce sounds with frequencies as high as 22,050 Hz. Sampling Theory • Aliasing – Failure to follow the Nyquist Theorum results in aliasing.
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 …

What is the best audio sampling frequency - LmK Music ...
https://lmkprod.com/best-audio-sampling-frequency/
The best sampling frequency is 2 times the frequency of the highest frequency of your incoming signal. Which, in case of music, is 20.000 Hz (20Khz). Therefore: 2 x 20.000 = 40.000. There we go: the best frequency for audio sampling is around 40Khz. And talking about industrial standards, we have the mighty 44.1 Khz at our disposal.
Theory of Upsampled Digital Audio
http://www.mlssa.com/pdf/Upsampling-theory-rev-2.pdf
the roll-off rate of anti-aliasing filters for 44.1 kHz sampling cannot be made gentle without severely compromising the baseband audio signal. If a sharp anti-aliasing filter is not used during recording at 44.1 kHz or when down-converting a 96 kHz master to 44.1 KHz, folded images of the baseband frequencies will fall right back into the audio
