Diffuse Signal Processing and Acoustic Source Characterization for Applications in Synthetic Loudspeaker Arrays
نویسندگان
چکیده
Active diffuse loudspeaker arrays can be implemented by incorporating a distribution of small radiating elements each characterized by processes that embed a unique diffuse impulse response. The properties of synthetic diffuse impulses are investigated both individually and collectively and algorithmic generation techniques presented. The diffuse properties of such synthetic arrays are confirmed both by polar response descriptors and spatial correlation techniques.

Holophonic Sources HOLOPHONIC SYNTHESIS OF MUSICAL SOURCES
The composition of a soundfield containing complex nearfield sources has interesting musical applications. A method is presented here using freefield expansions about exterior points of a harmonic multipole field. A derivation and verification are included. Binaural rendering is the natural method for displaying such soundfields. Some possible musical applications are discussed. INTRODUCTION Th...

متن کاملRobustness and Efficiency of an Acoustically Cou- Pled Two-source Superdirective Array
In a number of applications it is desirable to reproduce sound in a specific region whilst minimising it elsewhere. This can, in theory, be achieved using loudspeaker arrays and optimal, or superdirective beamforming techniques. However, these superdirective methods generally require a large electrical power at low frequencies, where the wavelength is large compared to the array, and are genera...

In this paper, the development and application of a universal audio-DSP (digital signal processor) board will be described. It is called freeDSP. Our goal was to provide an affordable real-time signal processing solution for researchers and the do-it-yourself community. Easy assembling and simple programmability were the main focus. A solution based on Analog Devices’ ADAU1701 DSP chip together...
متن کاملTowards Natural Acoustic Interfaces for Automatic Speech Recognition
Aiming at ’natural’ hands-free acoustic human/machine interfaces, the need for according distant-talking automatic speech recognition (ASR) systems increases and presents us with major signal processing challenges at the acoustic front-end. Considering interactive TV as a challenging exemplary application scenario, we investigate the structural problems presented by noisy and reverberant multi-...
