Model Matching Control for Binaural Reproduction over Loudspeakers

Recording and Reproduction over Two Loudspeakers as Heard Live Part 1: Hearing, Loudspeakers and Rooms

Innate hearing processes define the realism that can be obtained from reproduced sound. An unspecified system with two loudspeakers in a room places considerable limitations upon the degree of auditory realism that can be obtained. It has been observed that loudspeakers and room must be hidden from the auditory scene that is evoked in the listener’s brain. Requirements upon the polar response a...

Optimal Crosstalk Cancellation for Binaural Audio with Two Loudspeakers

Crosstalk cancellation (XTC) yields high-spatial-fidelity reproduction of binaural audio through loudspeakers allowing a listener to perceive an accurate 3-D image of a recorded soundfield. Such accurate 3-D sound reproduction is useful in a wide range of applications in the medical, military and commercial audio sectors. However, XTC is known to add a severe spectral coloration to the sound an...

Sound Field Reproduction Employing Non-Omnidirectional Loudspeakers

In this paper we treat sound field reproduction via circular distributions of loudspeakers. The general formulation of the approach has been recently published by the authors. In this contribution, we concentrate on the employment of secondary sources (i.e. loudspeakers) whose spatio-temporal transfer function is not omnidirectional. The presented approach allows to treat each spatial mode of t...

Perceptually Robust Headphone Equalization for Binaural Reproduction

Headphones must always be adequately equalized when used for reproducing binaural signals if they are to deliver high perceptual plausibility. However, the transfer function between headphones and ear drums (HpTF) varies quite heavily with the headphone fitting for high frequencies, thus even small displacements of the headphone after equalization will lead to irregularities in the resulting fr...
