چکیده

In this paper we elaborate and improve the multiple position room response equalization technique based on fuzzy c-means clustering of Bharitkar and Kyriakakis. Differently from their approach, we perform most of operations in the frequency domain and we apply the fuzzy c-means clustering to the amplitude room frequency responses at different positions. We show in the paper that working in the frequency domain can avoid many onerous operations performed in the approach of Bharitkar and Kyriakakis and thus a computationally efficient algorithm for multiple position room response equalization can be obtained. In all our experiments, the equalization performances of the proposed technique have always been similar to those of the technique of Bharitkar and Kyriakakis.

A Cluster Centroid Method for Room Response Equalization at Multiple Locations

In this paper we address the problem of simultaneous room response equalization for multiple listeners. Traditional approaches to this problem have used a single microphone at the listening position to measure impulse responses from a loudspeaker and then use an inverse filter to correct the frequency response. The problem with that approach is that it only works well for that one point and in ...

Combined quasi-anechoic and in-room equalization of loudspeaker responses

This paper presents a combined approach to loudspeaker/room response equalization based on simple inroom measurements. In the first step, the anechoic response of the loudspeaker, which mostly determines localization and timbre perception, is equalized with a low-order non-minimum-phase equalizer. This is actually done using the gated in-room response, which means that the equalization is incor...

Multiple-point equalization of room transfer functions by using common acoustical poles

A multiple-point equalization filter using the common acoustical poles of room transfer functions is proposed. The common acoustical poles correspond to the resonance frequencies, which are independent of source and receiver positions. They are estimated as common autoregressive (AR) coefficients from multiple room transfer functions. The equalization is achieved with a finite impulse response ...

Equalization of Loudspeaker and Room Responses Using Kautz Filters: Direct Least Squares Design

DSP-based correction of loudspeaker and room responses is becoming an important part of improving sound reproduction. Such response equalization (EQ) is based on using a digital filter in cascade with the reproduction channel to counteract the response errors introduced by loudspeakers and room acoustics. Several FIR and IIR filter design techniques have been proposed for equalization purposes....

Single-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels

In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...
