Problems solved by technology

The disadvantage of this technique is that a sound source that partly pans across the channel in the recording is not audibly reproduced through headphones because it is through a combination of two or more HRTFs in different directions rather than is rendered with the correct HRTF in the desired orientation

Abstract

A frequency-domain method for format conversion or reproduction of 2-channel or multi-channel audio signals such as recordings is described. The reproduction is based on spatial analysis of directional cues in the input audio signal and conversion of these cues into audio output signal cues for two or more channels in the frequency domain.
