SPATIAL EQUALIZATION OF SELECTED SOUND SOURCE BY DIGITAL INVERSE FILTERING

The work flektroakustyczne divided into three basic parts: In stereo reproduction, signals from 20Hz to 20kHz need to be replayed. With its ultra compact More information.

The decision anndrzej taken to design FIR filters of length. Local sound field reproduction using two closely spaced loudspeakers Ole Kirkeby a and Philip A. The study presents mathematical model of inverse equalizer; results of laboratory tests confirming effectiveness of its operation have also been given.

The issue in this case for problem solution is finding unknown impulse response of inverse filter g, while having at disposal original impulse response and expected result of these two values convolution, i.

For purposes of MLS sequences generation, recording, as well as determination dibrucki impulse response, CoolEdit, Aurora and Sample Champion software packages were used. In order to design the digital inverse equalizer, the transfer function H inv z needs to be arrived at so as to meet the relation 1.

Experimental data were recorded on PC hard disk dobucki digital wav format with 16 bit resolution and 48 khz sampling frequency. The reason for this was very high inhomogeneity of amplitude-frequency characteristics of the loudspeaker.

After decades of development room acoustical computer models have matured. It allows up to 10 base stations More information. Testing of selected loudspeaker properties Broadband loudspeaker Visaton model BG17 was used for designing of inverse digital equalizer.

Issues of active sound control gained much more attention abroad. Impulse responses of BG17 loudspeaker in enclosure were determined during second stage of research. Commins 1R. Hybrid methods combine the More information. Key Features Award-winning RoomMatch sound now in smaller, 2-way, point-source designs for high-level foreground music, under-balcony, zone-fill and vocalrange floor monitor applications Bose EMB2 compression.

One of them is Mourjopoulos method, and that is the method employed for designing of above-mentioned equalizers.

Two year Claritycap research programme finally answers an audio capacitors influence on sound quality. Inverse equalizers designed for purposes of BG17 loudspeaker in enclosure correction, for various angles of source radiation. KOWAL [7] work, presenting systems and principles of vibroacoustic processes control, as well as multi-author work [10] edited by A.

Therefore, considering economic and geometrical issues, utilisation of BG17 loudspeaker has been decided. The study of E. Measuring station, constructed from two channels: Hybrid methods combine the. Club installs More information. Designing of 10 litres closed box enclosure did not basically change these characteristics, either, what should be expected.
