Sample rate

Sample rate is a measurement of samples per second. A WAV file with a sample rate of 44.1 kHz contains 44,100 samples every second. So your computer, an incredible machine, divides a second into 44,100 equal parts.

While each sample reveals a sound wave's amplitude in that moment, a series of samples over time also reveals that sound's frequency. Frequency is a measurement of cycles per second, otherwise known as Hertz. Frequency, to put it another way, is a measurement of how many times a wave travels from peak to valley in one second. This determines a sound's pitch -- how high or low it sounds.

You might ask: does it really take 44,100 samples in one second to accurately reproduce a sound? It's a tribute to the human ear that the answer is yes, the ear is that subtle a sound receptor. If that seems a bit extreme, try listening to a sound file that's sampled at 22 kHz instead of 44.1 kHz. You'll hear a dramatic difference between 22,000 samples a second (low grade) and 44,100 samples a second (CD quality).
