HRTFs can virtualize multi-channel loudspeaker layouts on headphones.

Evidence

An interesting application for HRTF technologies with headphones is listening to of existing multi-channel audio content. Here, each loudspeaker of a multi-channel loudspeaker layout is simulated using an HRTF set. For example, to listen to stereophonic signals {xl, xr} over virtual loudspeakers in the directions of {−30◦, 30◦}, the signals are convolved with the HRTFs for each loudspeaker measured from the corresponding directions, as shown in Figure 14.9b (Blauert, 1996; Kirkeby, 2002). — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1930
