چکیده
By Michael Williams and Guillaume Le Dû 2 1 Independent Audio Consultant, Paris, France 2 – Radio France, Paris, France ing perfect reproduction of the sound environment. We must also be able to use this type of sound recording system in the recording of contemporary music which will often make use of the surrounding sound space, and of course sound effects and ambience where sound should be localised correctly within the total surrounding sound field.

Direction of Sound Wave Arrival Determination Using Time-Delay Estimation and Beamforming methods
This paper deals with direction of sound wave arrival determination using time-delay estimation and beamforming methods with utilization of static microphone array with fixed geometry configuration. Theoretical part describes main principle of both methods and possibility of program implementation. Experimental part proposes hardware design of the sensory systems separately for time-delay estim...
متن کاملMultichannel Linear Prediction for Blind Reverberant Audio Source Separation
A class of methods based on multichannel linear prediction (MCLP) can achieve effective blind dereverberation of a source, when the source is observed with a microphone array. We propose an inventive use of MCLP as a pre-processing step for blind source separation with a microphone array. We show theoretically that, under certain assumptions, such pre-processing reduces the original blind rever...
متن کاملRobust Superdirectional Beamforming for Hands-Free Speech Capture in Cars
The application of multichannel signal processing algorithms in front-ends of hands-free speech communication systems facilitates a better extraction of a desired source signal and allows for a suppression of unwanted noise and interference in car interiors. In this paper, a novel superdirective beamforming design method called the Robust Least-Squares Frequency-Invariant Beamformer (RLSFIB) is...
متن کاملLinear and Circular Microphone Array for Remote Surveillance: Simulated Performance Analysis
Acoustic beamforming with a microphone array represents an adequate technology for remote acoustic surveillance, as the system has no mechanical parts and it has moderate size. However, in order to accomplish real implementation, several challenges need to be addressed, such as array geometry, microphone characteristics, and the digital beamforming algorithms. This paper presents a simulated an...

A new singleand multichannel audio recordings database (SMARD) is presented in this paper. The database contains recordings from a box-shaped listening room for various loudspeaker and array types. The recordings were made for 48 different configurations of three different loudspeakers and four different microphone arrays. In each configuration, 20 different audio segments were played and recor...
