The invention provides a method for simulating a 3D sound environment in
an audio system using an at least two-channel reproduction device, the
method including generating first and second pseudo head-related transfer
function (HRTF) data, first using at least one speaker and then using
headphones; dividing the first and second frequency representation of the
data or using a deconvolution operator on the time domain representation
of the first and second data, or subtracting the cepstrum representation
of the first and second data, and using the results of the division or
subtraction to prepare filters having an impulse response operable to
initiate natural sounds of a remote speaker for preparing at least two
filters connectable to the system in the audio path from an audio source
to sound reproduction devices to be used by a listener.
