Center-Channel Processing In Virtual 3-D Audio Reproduction over Headphones or Loudspeakers

摘要

Virtual 3-D audio processing systems for the spatial enhancement of recordings reproduced over headphones or loudspeakers generally provide a less compelling effect on center-panned sound components. We present virtual 3-D audio processing algorithm modifications that provide an improved spatial enhancement effect over headphones or loudspeakers even for sound components localized in the center of the stereo image, preserve the timbre and balance in the original recording, and produce a more stable 'phantom center' image over loudspeakers. The proposed improvements are beneficial, in particular, in computer and TV set audio systems or home theater 'sound bar' loudspeakers.
