Hi there,
Yes sure. You probably need FFMPEG developer, which for sure I'm. We'll be using it in our Python script. Will deliver app for your exact specification. Will make sure last audio file doesn't get too short. Your app will have GUI where you could specify input file and output directory etc. We'll then compile the code to make .exe of it. Please connect to me. I could be the best candidate!
Best regards,
Ishaq
