Seems to work. I'm looking for tips on how to speed up the program.

Tried: Running without GUI (a little faster but not as I wanted)

Severity: terrible (one update per 400 ms, no wait time included) Plus very high CPU usage

Purpose of the program: Measure noise exposure over time using the mic

  \$\begingroup\$Your script is way too long so I didn't bother to figure out how it works. But at a glance you called the same functions repeatedly using a regular pattern of arguments, don't do this. You can just store the arguments in alist and iterate through thelist to call the function using the current element as arguments. Or better, since each command has nothing to do with each other logically and causally, they don't need to be called sequentially. You can usemultiprocessing.pool.ThreadPool.starmap_async to do it.\$\endgroup\$

• \$\begingroup\$After I looked your code more closely, you should not make independent variables for the GUI elements that are constructed similarly. Rather, you should use a for loop to create them and keep track of them in adict, or use multithreading. And don't use elif ladder to check if a number is a certain range, it is a linear search and inefficient. You can usebisect.bisect to do it. Also, don't usetime.time for this purpose, it is imprecise, usetime.perf_counter.\$\endgroup\$

  \$\begingroup\$That question lacks a lot of context? What does the program do? Why do you want to speed it up? Does it lag? If so, how bad is it? Did you try to profile it? Did you try to run the logic without the GUI or the GUI without the logic?\$\endgroup\$
