Exhaust note through car audio +1Rofl

Tunerfreak · Post by **Tunerfreak** » 28 Dec 2006, 01:50

Ive recently installed some rather ok car audio into my car, and I was wondering if there was a way to simulate the exhaust note through the car audio system?

I was thinking if I made a link between the alternator or the ecu or something to calculate the rpm I could find a way to run through auxilery in a simulated exhaust note? Something like a deep version of the alternater noise you get through the speakers when power and speaker wires meet would be an interesting experiment.

Maybe there is a way to caluculate the shutting of the throttle and simulate a blow off valve noise?

Im just intrieged by the though of it all so please dont mark me down for the nutty farm... yet

I wouldn't have any clue how to do that, but my cousin's Lexus has a weird sound always coming through the speakers that changes pitch respectively to the RPM of the engine.

That noise shoul be from th alternator. Either the power wire is too close to the speaker wires transfering the noise or an amplifier may be faulty. Try pullig you inputs out of the amplifier if its running one and see if you can single out the wire othrwise split up th power and speaker wires as much as possible, e.g. run them down opposite door sills.

Hope it helps

P.S yes I know the work keyboard is faulty and filled with dust

@Hazmat- that's negative sound I believe, it's meant to cancel out the sound of the engine to make it seem more refined

If you wanna be able to hear your exhaust note, just strip all the sound deadening out of your car!

Opening a window works too.

Yeah, but that gets you cold; Take out the exhaust heat shield underneith the body and all the sound proofing, and you end up warmer!

Disclamer- if your exhaust heat shield is anywhere near your fuel tank or fuel lines, don't even think about doing it!

Yeah, or your manifold might be in danger, which makes your floor fall out.

EDIT: Cold? What is that? Is it something I can eat?

Some systems may have that feature, but the sound im sure Haz is experiencing reprsents the sound of the Alternator working its guts off coming through the speakers, its fun but very irritating.

I dont want to make my exhaust note more audiable I want to be able to play with it inside the car at funny pitches and volumes just for fun, and maybe confuse the Rexes and Evos with a fake BOV

Ive always got my window open when possible as my cheap freebie muffler dosn't cut it otherwise

Cold is the definition of where I live... at summertime

i think it's quite obvious you've never visited Holland before....at the moment, there's a reasonably strong wind, with a bit of rain. Max temperature today: 5 degrees Celsius...

and opening a window wouldn't be that effective: when you're driving like 60 mph, the noise of the wind will be louder then your engine's noise...

Why would you bother? The easiest way would be to get a recording of the BOV sound or whatever, and just work out how to play it accurately. Similiar to Ashley Simpsons lip-syncing trick. Interesting theory, but still don't know why you'd want engine noise in your stereo. If you want engine noise, put in an engine that will make killer noise and go off like a banshee!
