I'm studying engineering school and within the framework of a technical project, we must make an acoustic simulator, simulating the sound of an engine for an electric car in order to limit injuries to pedestrians.
The ideal would be to achieve design a device where the sound evolve as a function of engine speed, speed that you would change just a potentiometer, but already in the first instance, if we could just produce an engine noise would not be bad at all!
Do you have an idea of electronic assembly to produce engine noise?
To reproduce this sound, you have various solutions, we must know where you want. Either you study the frequency curve and you try to reproduce it, or you do mechanically, or you work on a sample (in my opinion, the + single).
A sample placed in ROM, with a knob that adjusts the transmission speed (taken from the accelerator pedal), it must do!
Okay, so, it loses some of the first quality of an electric motor. What is nice is that you can put the V12 sample of Ferrara. :-)
Thanks for your answer robin29, in our case we should not use sample but reproduce the sound of an engine with the mail. Your solution "to study the frequency curve and reproduce" is interesting, but just, you know how to reproduce a sound with a particular frequency ?
Yes, very simply, by saving in a software and studying its curve. But when the play! There is a huge step. It may consist of several waveforms mixed (explosions, grinding noises, exhaust, etc.. And to separate them. It will not be of the pie. It takes a special software for that, and I do not know!
