Abstract:
1. A spatial processing stereo system (SPSS), comprising: a plurality of filters for filtering a left audio signal and a right audio signal; a room response generator; a user interface for entry of parameters associated with the spatial attributes of a room; a user response processor that receives the parameters from the user interface and generates coefficients that are used by at least one of the plurality of filters and being in receipt of a room impulse response that is also used by at least one of the plurality of filters; and at least two additional audio signals that are generated with filters that use the coefficients filtering the left audio signal and right audio signal with a signal processor that receives at least the right audio and the left audio signal and generates at least a left signal, a first left surround signal, a right signal and a first right surround signal with a coefficient matrix using the coefficients where the signal processor includes a pair of shelving filters and a pair of delay lines and generates at least a second left surround signal and a second right surround signal.
