the sample rate = samples per second
a sample is a measurement of aptitude
The sample rate is how many measurements of the sound are taken each second. The more samples the more detail about where the waves rise and fall in recording.
The Sample Rate is measured in Samples Per Second
Every sample is a measurement of amplitude
A common audio sample rate for music is 44,100 samples per second and the unit for the sample rate is hertz (Hz) So 44,100 samples per second is 44,100 hertz or 44.1 kilohertz (kHz)
Nyquist Sampling Theorem
to capture a wave you need to be a minimum of 2 samples per wave length
so sample rate must be At least twice the wave’s frequency
S > 2F
F= frequency or wave length
S= Sample
example if I wanted a 20 KHZ
S> 20,000
