Abstract:
Embodiments relate to b-chain processing for a spatially enhanced audio signal. A system includes a b-chain processor. The b-chain processor determines asymmetries between the left speaker and the right speaker in frequency response, time alignment, and signal level for a listening position; and generates a left output channel for the left speaker and a right output channel for the right speaker by: applying an N-band equalization to the spatially enhanced signal to adjust for the asymmetry in the frequency response; applying a delay to the spatially enhanced signal to adjust for the asymmetry in the time alignment; and applying a gain to the spatially enhanced signal to adjust for the asymmetry in the signal level.
