Thanks for your amazing code.Can you give me some suggestions about how to know the start time and end time? Just as I identify the sounds of cars and helicopters in a video, how do I know the start and end times of the car and the helicopter, respectively? Thanks.

Thanks for your comment. The problem is easy if the sounds of cars and helicopters are easily detected by using some metrics such as gain (dB), but in other cases it is very difficult. I don't know how many sounds of cars and helicopters you have, but in that case I think you first need to clip some of the sounds of cars and helicopters by yourself and train detectors of them with the clipped sounds. Then, automatically detect the sounds of cars and helicopters using the detectors. Finally, manually check if the detected sections are correct or not.
