Understanding sample rate

When working with digital audio, there are two audio attributes that you need to be aware of and that is Sample Rate and Bit Depth. Both speak to the quality of the audio and although the Bit Depth is probably a bigger indicator of the quality of the audio, the Sample Rate can really mess you up, if you don't know what you're doing. If you select a clip, in the Project panel, which is what we're looking at here, we know that we get an overview of the attributes of that file, up at the top of the Project panel.

And right here, first, in the left-hand corner of the attributes at the bottom is the Sample Rate. Here, it's 44,100 Hz. You see, the Sample Rate refers to how many samples were taken of the audio, per second. Audio is made digital by taking snapshots of the audio wave file as a certain amount of times per second, measured in hertz. And so 44,100 Hz means there is 44,100 samples taken per second. This is a very common sample rate for CD-quality audio.
