Understanding sample rate
- It's really important to understand that all audio we hear is actually analog. Nothing we actually hear is in the digital realm. It has to go from analog into digital, and then back out from digital back out to analog. And how we do that is we sample the analog waveform, and those pictures that we take in equidistant times allows us to reproduce the analog audio or reproduce the audio in the digital world in zeros and ones. And then, it again allows us to play it back out. The process of doing this is sample rate. Now, if you'll look, sample rate will take different pictures, just like you're taking a picture with your digital camera and on the waveform, and you would think that it would be all smooth, but it's not. All it does is take these pictures, and they want to go directly from one point to the next point to the next point to the next point. The more points you have, the more smooth that you can make the sample wave at the end. So the points, the more samples that you take of…
