摘要： An audio quality enhancing apparatus and method is provided in which a microphone array has a non-uniform configuration and thus a beam pattern of a desired direction is obtained in a wide range of frequencies including higher frequency bands and lower frequency bands even when the microphone array is relatively small. The audio quality enhancing apparatus includes at least three microphones which are disposed in a non-uniform configuration, a frequency conversion unit configured to transform acoustic signals input from the at least three microphones to acoustic signals of frequency domain; a band division and merging unit configured to divide frequencies of the transformed acoustic signals into bands based on intervals between the at least three microphones and to merge the acoustic signals in the frequency domain into signals of two channels based on the divided frequency bands; and a two channel beamforming unit configured to reduce noise of signals including input from a direction other than the direction of a target sound by performing beamforming on the signals of the two channels and to output the noise-reduced signals.

摘要： An apparatus and method reduce noise in a complex spectrum domain to extract a target signal from input signals containing noise and target speech. Noise estimation may be performed through a filter with a filter learning coefficient that is updated according to a prior-signal-to-noise ratio (prior-SNR). Also, noise estimation accuracy may be improved by using confidential weighted scores. The target signal may be extracted by representing candidates of the target signal as at least two circles in the complex spectrum domain using the estimated noise and then geometrically calculating the intersections of the circles.
