Fig. 8From: Acoustic object canceller: removing a known signal from monaural recording using blind synchronizationExamples of spectrograms. Upper left shows the recorded signal where we used target (iii), BGM, and set input SNR at 0Â dB and sampling frequency mismatch at 62.5 ppm. Upper right shows the target (iii). Lower left shows the target signal estimated by the conventional amplitude-based method. Lower right shows the target signal estimated by the proposed methodBack to article page
