<t>Sound-reactive installation, 300 LEDs on 4m sculpture. Gallery 10-20 lux ambient.<br/>
<br/>
Linear PWM (sound amp to brightness) too harsh. Peaks burn eye, mids wash out.<br/>

Gamma correction tables (2.2) for perceptual brightness, but math hurts. Simple lookup table I can paste into ...

<t>Working on a sound-reactive installation, 300 WS2812B LEDs across a 4-meter sculpture. Gallery lighting is moody, around 10-20 lux ambient.<br/>
<br/>
Issue: my linear PWM mapping (sound amplitude to LED brightness) looks too harsh. Bright peaks burn the eye, mid-range washes out.<br/>

<t>Mixed-media artist po ako, painter primarily but the past 3 years naka-integrate na ako ng electronics sa installations ko. LED fields, sound-reactive sculptures, basic interactive pieces. My questions tend to be aesthetic-driven (color temperature, dimming curves, animation pacing) more than ...
