Every sound effect starts with a simple wave. Different wave shapes create different tones.

💡Fun Fact: The classic 8-bit video game sounds used square waves because early computers could only produce "on" or "off" signals - perfect squares!

ADSR: Shaping Sound Over Time
The envelope controls how a sound starts, sustains, and fades away. This is what makes a piano sound different from an organ.

🎹Try This: Set Attack to 0 for a sharp "pluck" like a guitar, or set it high for a slow "swell" like a violin!

Filters: Sculpting Frequencies
Filters remove certain frequencies from a sound. This is how you make sounds feel "muffled" or "bright".

🎧Movie Trick: When a scene goes underwater, sound designers use a low-pass filter to remove high frequencies - just like real water does!

🎮Game Dev Secret: Most "laser" sounds use a descending frequency sweep, while "power-up" sounds use ascending frequencies. Our brains associate rising pitch with gaining something!
