This scale factor ambiguity is the same across all channels but can differ between the subbands and therefore, limits the usability of such estimates. In this contribution, a method that uses multiple filterbanks is proposed that utilizes overlapping passband regions between these filterbanks to find scalar correction factors that make the scale factor ambiguity uniform across all subbands. Simulation results are provided, showing that the proposed method accurately identifies and corrects for these scale factors. View pdf
