depende po kasi kung paanong sound activated ang gusto niyo. Kung simpleng base lang sa loudness madali lang yun i-implement sa OP AMPS..... Pero kung gusto mo halimbawa specific sa bose mo medyo mahirap yun.... kailangan mo pa siguro ng DSP for voice processing. Basta medyo mahirap yun kung trip trip lang. Pwede ka gumawa ng sound activated LED gamit ang OP AMP?

Bale Kailangan mo lang ng microphone tapos connect po sa op amp. parang meron ka treshold tapos gagawin ng op amp ikukumpare lang niya ying taas ng voltage sa treshold. Siyempre pag malakas ang boses mas malakas ang output ng mic di ba? basta search ka na lang sa net ng op amp magkakaroon ka ng idea.
