I have a Python code which listens and detects environmental sounds. It is not my project I found it on web (SoPaRe). With ./sopare.py -l command, it starts recording sounds but in infinite loop. When you want to stop it, you have to press CTRL+C. I talked with the author and he said, the program does not have a time limiter. My purpose is to stop this program automatically after 10 seconds etc. I tried to kill it via kill PID, but PID changes every time when program worked. How can stop it after a time interval via bash?

Alternatively, I can execute this command from python with os.system() command.

If you help me, I will be glad. I'm not only dealing with this program, so I managed all chain via shell script. This is why I'm looking for unix help. Alternatively, I can execute this command from python with os.system() command. You can show via Python, however my first choice is bash.
