What’s sampling rate? And why does it matter for music?


Do you constantly hear people talking about sample rate in music? But don’t you know what it really is?? Well, my friend, you have come to the right place.

Fundamentally, sample rate is the result of digitizing audio. While analog sound waves are continuous, digital music is made up of many small data points read one after another.

But we are getting ahead of ourselves.

The audio sample rate is literally the number of “samples” taken per second. This is measured in Hertz (Hz).

Now the going rate is CD or FLAC, which is lossless audio file. This clock at 44.1 kHz. In practice, this means that for every second of music, 44,100 samples are taken from a continuous analog signal to create a digital file.

The higher this number, the better the audio quality – up to a point, but we’ll get to that soon. This graph is a good visualization tool to know how it works:
