Abstract:
1. A transitioning system from stereo to simulated surround sound, comprising: a filter transforming a dipole signal to a filtered dipole signal; a first attenuator transforming the dipole signal into an attenuated dipole signal, where the filter and attenuated dipole signals are fed to a mixer that combines a fractional sum between the filtered dipole signal and the attenuated dipole signal thus generating a mixed signal; a second attenuator transforming a monopole signal to an attenuated monopole signal; a first adder summing the mixed signal and the first attenuated monopole signal to obtain a first speaker channel; and an inverter creating an inverted mixed signal, where the attenuated monopole signal and the inverted mixed signal are fed to a second adder summing the attenuated monopole signal and the inverted mixed signal to obtain a second speaker channel.
