    It’s really simple.

    Sound is air vibrations at different strengths (volume) and frequencies (pitch). Taller waves are loud. Thinner waves are higher pitched. The math looks like this:

    Volume * sin( Pitch * time)

    Generally, low pitch sounds are louder and easier to see in a sound wave. A kick is really easy to spot. The rest of the weird janky movement of the sound wave is like a bunch of these equations added up to create the sound… generally.

    The trick to understanding sound is that it’s a difference over time. The change in pressure is registered by your brain. A record player is literally just the physical transcription of this math and the speaker is just oscillating back and forth to reproduce the sound.

    Okay maybe it’s not super simple, but I hope this helps.
