No file, test, or entry point is named. Locate the top-k energy selection implementation and trace how per-frame normalization and global selection are used; done means documenting the rationale clearly enough to resolve the question.

Description

Thank you for your great work!

I have a question regarding the top-k energy selection process. Since the energy is normalized per frame, the values across different frames are on different scales. Could you please explain the rationale behind performing a global top-k selection across all frames after this per-frame normalization?
