In this video, Paul Murphy discusses the fundamental concept of amplitude in audio files.
- [Instructor] In the previous video, we discussed frequency…or the cycles per second of a sound wave.…The other important part of measuring a 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.…Looking at this file that I have open…in the WaveForm editor,…I can tell just visually that I have three sounds here,…and each one is louder than the previous.…Let's play back to confirm this.…(solid tones)…so 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 the scale on the vertical axis here.…
At the top we have 0dBFS, or decibels full scale,…and that's as loud as anything can be,…and down the bottom here we have infinity,…or basically silence.…This is why all amplitude is expressed as a negative number…because you can't actually go above zero,…and the scale married underneath for fluctuations…that go below this line here,…or what's known as the zero crossing point.…
