Generating PC music analysis and transmitting through serial for Arduino
hello everyone,
what interested in doing longest of time use computer analyze global music (players, browsers, games, etc..), , send analyzed data through serial port , 1 of arduinos.
the goal here program overhead individually addressable led strips pretty other led's or lights matter.
i've been searching forum after forum of people trying same thing, tutorials made no sense me , closest got use arduino adc , of op amps plot aux (or similar) output within range of 0 5v (2.5 neutral middle).
however approach seems little bit overkill imagine there noise , not mention having build test , design whole thing without having oscilloscope.
ideally want find way use c# visual studio 2015 (as matter of fact found tutorial on it, couldn't understand 3 step guide pace jumping crazy 'download this' 'you're pretty now', though i'm totally lost in-between).
anyway if anyone's done similar this, please suggest sort of starting point me.
thanks!

what interested in doing longest of time use computer analyze global musicdo mean spectrum analysis? ...if don't know is, search youtube "arduino sepectrum analyzer". (it sounds want computer actual spectrum analysis, can find videos show led effect looks like.)

(players, browsers, games, etc..), , send analyzed data through serial port , 1 of arduinos.in case, arduino serial-controlled lighting controller. should easy. the "hard part" software running on computer.
the fft/dft/fht programming behind spectrum/frequency analysis advanced dsp (digital signal processing) can find libraries make lot easier. you'll need know how intercept audio "inside" computer.

the closest got use arduino adc , of op amps plot aux (or similar) output within range of 0 5v (2.5 neutral middle).of course, if computer doing frequency analysis, you don't need analog input @ all.
if want use analog input, can bias input two equal-value resistors , capacitor. work line-level audio signal or reasonably loud headphone signal.
if want pick-up sound microphone, need preamp, can built op-amp.
