A method for virtually widening stereo audio signals played over a pair of loudspeakers, the method comprising: receiving stereo audio signals, the stereo audio signals comprising a left audio signal and a right audio signal; supplying the left audio signal to a left channel and the right audio signal to a right channel; employing acoustic dipole principles to mitigate effects of crosstalk between a pair of loudspeakers and opposite ears of a listener, without employing any computationally-intensive head-related transfer functions, HRTFs, in an attempt to completely cancel the crosstalk, said employing comprising, by one or more processors: approximating a first acoustic dipole by at least inverting the left audio signal to produce an inverted left audio signal and combining the inverted left audio signal with the right audio signal, and approximating a second acoustic dipole by at least inverting the right audio signal to produce an inverted right audio signal and combining the inverted right audio signal with the left audio signal; applying a single first inverse head-related transfer function, HRTF, to the second acoustic dipole to produce a left filtered signal, the first inverse HRTF being applied in a first direct path of the left channel rather than a first crosstalk path from the left channel to the right channel; applying a single second inverse HRTF function to the first acoustic dipole to produce a right filtered signal, the second inverse HRTF being applied in a second direct path of the right channel rather than a second crosstalk path from the right channel to the left channel, wherein the first and second inverse HRTFs provide an interaural intensity difference, IID, between the left and right filtered signals; low-pass filtering the left audio signal to produce a low-pass filtered left signal; combining the low-pass filtered left signal with the left filtered signal to produce a combined left filtered signal; low-pass filtering the right audio signal to produce a low-pass filtered right signal; combining the low-pass filtered right signal with the right filtered signal to produce a combined right filtered signal; enhancing the combined left filtered signal by at least high pass filtering the combined left filtered signal to produce a left enhanced signal; enhancing the combined right filtered signal by at least high pass filtering the combined right filtered signal to produce a right enhanced signal; and supplying the left and right enhanced signals for playback on the pair of loudspeakers to thereby provide a stereo image configured to be perceived by the listener to be wider than an actual distance between the left and right loudspeakers. receiving stereo audio signals, the stereo audio signals comprising a left audio signal and a right audio signal;
