What is the sampling rate?

Sample rate is the number of samples of audio carried per second, measured in Hz or kHz (one kHz being 1 000 Hz). For example, 44 100 samples per second can be expressed as either 44 100 Hz, or 44.1 kHz. Bandwidth is the difference between the highest and lowest frequencies carried in an audio stream.Apr 27, 2016 read more

For example, the current sample rate for CD-quality audio is 44,100 samples per second. This sample rate can accurately reproduce the audio frequencies up to 20,500 hertz, covering the full range of human hearing. read more

The sampling frequency or sampling rate, f s, is the average number of samples obtained in one second (samples per second), thus f s = 1/T. Reconstructing a continuous function from samples is done by interpolation algorithms. read more

A PC's sound card typically will sample a received analog signal, such as through a microphone, and digitize it for use by the computer. A higher sampling rate provides a better quality reproduction than a lower sampling rate. read more
