In recent years, downtime and information loss problems of server computers have become more critical. Even if a server has antivirus and CPU overload checking programs, it may occasionally be broken or slowed down. Hypothetically, there are possible indications of the problems under specific external situations such as high temperature, low fan speed, and extreme main board vibration. In order to...
Distributed microphone systems can be used to enhance intelligibility for a speaker of interest (SOI) in a noisy environment of multiple speech sources (cocktail party scenario). For finite microphone distributions, however, interfering speech sources leak into the beamformed signal and degrade intelligibility. This article introduces an auditory inspired post-processing algorithm for beamformed signals...
The performance of sound source location (SSL) algorithms with microphone arrays can be enhanced by processing signals prior to the delay and sum operation. The phase transform (PHAT) has been shown to improve SSL images, especially in reverberant environments. This paper introduces a modification, referred to as the PHAT-β transform, that varies the degree of spectral magnitude information used by...
