What would be the key features of an audio track or set of tracks (like 5.1) for identifying film audio tracks that have a clear unbalance between speech levels and sound effects levels (apart from the obvious rms diference between tracks)? And how could they be extracted or calculated?
It's for a machine learning project about automatic identification of such files and ulterior processing/fixing. The imbalance could be on the same track, or in a combination of several ones.
Thanks in advance.
