Selective Listening Point Audio Based on Blind Signal Separation and Stereophonic Technology
A sound field reproduction method is proposed that uses blind source separation and a head-related transfer function. In the proposed system, multichannel acoustic signals captured at distant microphones are decomposed to a set of location/signal pairs of virtual sound sources based on frequency-domain independent component analysis. After estimating the locations and the signals of the virtual...
متن کاملAdaptive Blind Audio Signal Separation System using a TI DSP
Blind Signal Separation (BSS) deals with the problem of separating independent sources from their observed mixtures while both the mixing process and original sources are unknown. Examples of BSS algorithms employed in acoustical applications can be found among others in audio teleconferencing systems, hearing aids, noise cancelling etc. Such systems usually involve speakers that are at some un...
متن کاملA Stereophonic Acoustic Front-End for Distant-Talking Interfaces based on Blind Source Separation
In this contribution, an acoustic front-end for distanttalking interfaces that only requires two microphone signals is presented. It comprises a directional blind source separation (BSS)-based noise and interference estimation scheme and Wiener-type filters for noise and interference suppression. The proposed front-end and its integration into a speech recognition system is analyzed and evaluat...
متن کاملResearch and Application of Fetal Electrocardiogram Blind Signal Separation Technology
FECG (Fetal Electrocardiogram) is weak signal indirect monitored between the electrode that placed upon the mother abdominal the matrix surface, which contains all the forms of jamming signal. How to separate the Fetal from the strong background interference has important value of clinical application, but this is a difficult problem in the signal processing field. Independent Component Analysi...
متن کاملMultichannel Blind Signal Separation And Reconstruction - Speech and Audio Processing, IEEE Transactions on
Separation of multiple signals from their superposition recorded at several sensors is addressed. The methods employ polyspectra of the sensor data in order to extract the unknown signals and estimate the finite impulse response (FIR) coupling systems via a linear equation based algorithm. The procedure is useful for multichannel blind deconvolution of colored input signals with (possibly) over...
