Understanding amplitude
- [Instructor] An important part of measuring sound is amplitude or how much the sound wave fluctuates up and down. Files with smaller fluctuations will be softer, and bigger fluctuations will be louder. Let's have a look at this file over here, Amplitude. Just by looking at this, I can tell visually that I have three sounds here, and each one is louder than the previous. Let's play this back just to confirm. (program beeps) The way that we measure amplitude is in decibels, or dB for short, and that's a small d and an uppercase B. And that's this scale on the y-axis here. At the top, we have zero dBFS, or decibels full scale, and that's the loudest anything can be. And in the middle here, we have infinity or basically silence. This is why all amplitude is expressed as a negative number, because you can't go above zero. And the scale is mirrored underneath for fluctuations that fall below what's known as the zero crossing point, which is this line here. So if I go up to my navigator…
