Abstract
The disclosure provides an approach for adaptive sound image width enhancement. A method of adaptively correcting sound image width is provided. The method includes obtaining an audio signal. The audio signal is associated with one or more audio channels. Each audio channel is associated with a position of an audio source with respect to a reference point within a local reproduction system. The method includes decomposing the audio signal into mid signal, side signal, and unprocessed signal components. The method includes applying respective correction gains to each of the mid signal, side signal, and unprocessed signal components. The respective correction gains are based on a physical distance between a first loudspeaker and a second loudspeaker within the local reproduction system. The method includes rendering, after applying the respective correction gains, the mid signal, side signal, and unprocessed signal components to the first and second loudspeakers.
