Pycaw is a Python library designed exclusively for controlling audio devices on Windows systems. It allows programmatic access to audio sessions, volume control, and sound device management on the Windows platform.
Note: Pycaw does not support macOS or Linux. It is built specifically for Windows using Core Audio APIs. If you're looking for similar functionality on other platforms, you'll need alternative libraries.
