Improving headphone user experience in ubiquitous multimedia content consumption : a universal cross-feed filter

Li, FF

Abstract

High performance audio and video codecs and ever
increasing bandwidths of data communications networks have
enabled multi-platform delivery of high definition media content
via transmission channels such as terrestrial broadcast,
broadband IP networks and mobile telecommunications systems.
Media content consumption becomes ubiquitous and more
personalized than ever before and audio is often rendered
through headphones. Attentions should be paid to sound quality,
and therefore high definition virtual auditory space (VAS) is
sought after as an ideal solution. Stereophonic and surround
sound are still commonplace while spatial audio is in its infancy
to meet the demand of 2.5/3 D high definition video. Binaural
headphone rendering offers ultimate spatial audio and source
localization; however, individual head-related transfer functions
(HRTFs), head movement tracking and suitably synthesized
signals are needed to achieve its full potential.
Most audio recordings to date are intended and hence best for
loudspeaker rendering. Good cross-feed filters can be an interim
solution to improve headphone user experience. This paper
proposes a universal cross-feed filter. HRTFs at specific source
locations were first considered to derive the cross-feed filters.
User preferred HRTF parameters were also identified with a
variety of representative soundtracks. The transfer functions
were measured and simplified to derive user preferred universal
cross-feed filters for all. Validation tests confirmed improved
listening experience.
