[COMMAND_EXECUTION]: Uses subprocess.check_call to automatically install missing Python dependencies via pip. The package names are hardcoded inside the script, preventing arbitrary package injection.
[COMMAND_EXECUTION]: Uses subprocess.run to invoke the demucs command-line utility for audio stem separation. The input file path is validated for existence and supported extensions, and is executed safely as a list element rather than through a shell interpreter.
[DYNAMIC_EXECUTION]: Uses the built-in __import__() function to dynamically check for the presence of required Python packages at runtime. The module names are strictly limited to a predefined hardcoded list.
[EXTERNAL_DOWNLOADS]: Downloads a pre-trained neural network model weights file (.pth) for piano transcription from a Zenodo public repository if not found locally. The download URL is hardcoded and directly satisfies the primary functionality of the tool.
