Subband Approach to Bandlimited Crosstalk Cancellation System in Spatial Sound Reproduction
Crosstalk cancellation system (CCS) plays a vital role in spatial sound reproduction using multichannel loudspeakers. However, this technique is still not of full-blown use in practical applications due to heavy computation loading. To reduce the computation loading, a bandlimited CCS is presented in this paper on the basis of subband filtering approach. A pseudoquadrature mirror filter (QMF) b...
متن کاملObjective and subjective analysis of effects of listening angle on crosstalk cancellation in spatial sound reproduction.
A comprehensive study was conducted to explore the effects of listening angle on crosstalk cancellation in spatial sound reproduction using two-channel stereo systems. The intention is to establish a sustainable configuration of crosstalk cancellation system (CCS) that best reconciles the separation performance and the robustness against lateral head movement, not only in theory but also in pra...
متن کاملSound localization in individualized and non-individualized crosstalk cancellation systems.
The sound-source localization provided by a crosstalk cancellation (CTC) system depends on the head-related transfer functions (HRTFs) used for the CTC filter calculation. In this study, the horizontal- and sagittal-plane localization performance was investigated in humans listening to individualized matched, individualized but mismatched, and non-individualized CTC systems. The systems were si...
متن کاملThe directional effect of crosstalk in multi-channel sound reproduction
The effect of increasing inter-channel crosstalk in multichannel reproduction is investigated with auditory model simulations. A standard auditory model is used to estimate the perceptions of listeners in multichannel listening with crosstalk. ITD and ILD cue values are computed for three different loudspeaker setups. The crosstalk is varied between -14 dB and -38 dB. The results show that when...
متن کاملSpatial Audio Reproduction: Towards Individualized Binaural Sound
INTRODUCTION The compact disc (CD) format records audio with 16-bit resolution at a sampling rate of 44.1 kHz. This format was engineered to reproduce audio with fidelity exceeding the limits of human perception, and it works. However, sound is inherently a spatial perception. We perceive the direction, distance, and size of sound sources. Accurate reproduction of the spatial properties of soun...
