Car engine sound question

I want to create an engine sound that slows down when the car slows down and speeds up when the car speeds up ,How can i do this?.

try to use one idle sound file for engine sound

and then when you want to speed up - pitch up that sound and pitch down for slowing down

I don't know if this would do exactly what you want, but the XAudio object has an action to adjust the frequency of your sounds, maybe you could try adjusting it based on the speed of the car somehow?

I don't have much experience with the XAudio object so i can't help much more than that

EDIT: shinkan beat me to it

sorry

Yeah what they said, adjust frequency ratio to lerp(lowestfrequency,highestfrequency,currentspeed/maxspeed)

You'll have to mess with the frequency ratios to determine what sounds best for high and low

I took the advice and it works like a charm ,Thanks everyone.
