Sound is reproduced if a loudspeaker diaphragm is moved according to the recorded waveform. Source separation and localization, noise reduction, general enhancement, acoustic quality metrics; The corpus contains the source audio, the retransmitted audio, orthographic transcriptions, and speaker labels. As an example, sound is usually a signal that is composed of the numerical addition, at each time t, of signals from several sources. Kameoka, H. each source is calculated using the inverse short-time Fourier transform (iSTFT) of the estimated magnitude spectrogram of each source together with either the original or the modified phase of the mixture sound. Guided source separation Assuming sparsity of speech in the STFT domain, BSS can be achieved by estimating, in an alternating fashion, rst which source is dominant in each time-frequency (tf) bin, and then the statistics of each source from the tf bins it dominates. sh reference.
