Closed Posted 7 years ago Paid on delivery

I'm in need of analyzing various sound samples (in WAV/AIFF) and detecting Automobile (Car) engine turning on and off. The sounds are recorded from a microphone placed below car (in dead center).

Initially, some analysis will be done ie FFT, and finding the shortest amount of time needed for detecting the engine been turned off. Then a program shall be written in C that will take as input a file. It will generate a log indicating the exact times the event happened. This code should run in either PC (and later) embedded environment, ie Arduino.

Various types of recordings of cars will be played to test how well it detects the car engine been turned OFF
