Engine Sound Generator

 

Introduction


You are driving your unremarkable car through the highway while hearing the most boring engine sound 
in the world coming from under the hood. While you are not rich enough yet to buy the fast Porsche 
that passes by, you wish you could at least hear its roaring engine sound in your usual car. And I have 
the solution!
I am Homayoon Farrahi, hardware engineering student at University of Tehran. I love fast cars and the 
exciting sound they make. Not being rich myself to afford those cars, I decided to embark on a journey 
to make my wish come true. I want to build a device that produces realistic sports cars engine sounds 
inside usual cars.

 

The Need
The need for excitement exists in every single human being. One of the ways with which many people 
become excited is the engine and exhaust sound of cars. Sports cars are built for excitement, and their 
manufacturers pay special attention to the sound that is produced from the cars’ exhaust system. They 
spend a lot of time tuning the engine and exhaust to make sure they get the sportiest sound they can.
While these sports cars may not be accessible or affordable for some people, these people still want to 
hear a good sound from their usual car. This leads to them changing the exhaust systems with third 
party exhaust kits which are absolutely not standard at all. Some even make a hole in the stock exhaust 
to make its sound louder. The unrealistic sound produced by these methods is far too different from the 
sound of real sports cars. There needs to be a device which produces high quality realistic sports engine 
sound.
 

 

Engine Sound Generator


This is the device that I am going to make. Everything is inside one small box that can be put anywhere 
on the dashboard. It features a complete range of different types of realistic car sounds. New sounds 
can be added to the device at any time. The engine data comes from the standard OBD II connector that 
exists inside the cabin of mostly all of the cars. It will output the sound to a 3.5 mm jack that is easily 
connected to the car’s audio system.


Current Project State


I have been working on the project for some time. I have used an ATmega32a microcontroller. I have 
confronted many big and small problems, and I have solved most of them. The learning process that I 
have been through has been really amazing, and every problem I solved got me one step closer to 
finishing the project. However this microcontroller has a really low performance and cannot meet the 
project’s real-time requirements. And thus a change of microcontroller is needed.
Currently only one waveform file can be played continuously. Whereas for optimum quality, real-time 
concurrent playback of at least four waveform files is necessary. In the current state the selected engine 
rpm is obtained from the computer through microcontroller’s UART interface and engine load is not 
used in combining the sounds.
