Sound and Digital Audio

Ripples in air propagate at the speed of sound, approximately 343 meters per second at room temperature and atmospheric pressure.
The intensity of sound is measured in decibels (dB).
The branch of physics that studies sound is called acoustics.

Sound Waves and Vibrations

When an object vibrates in the air by moving back and forth, it creates pressure waves that travel through the air as sound waves.

Digital Audio Fundamentals

Sound pressure levels (loudness or volume) are measured in decibels (dB).
The sampling rate in digital audio refers to the number of times per second that the audio signal is captured or sampled.
The purpose of quantization in digital audio is to convert the continuously varying amplitude of an analog signal into a discrete set of digital values.
The bit depth in digital audio recordings represents the number of bits used to represent the amplitude of each sample, which determines the resolution and accuracy of the digital signal.
Increasing the sample rate in digital audio recordings can improve quality by capturing more detail and reducing aliasing artifacts.
The quality of a digital recording is determined by the sample size, with larger sample sizes allowing for greater dynamic range and lower noise floors.
