Sampled and discretized of short-time Fourier transform and non-negative matrix factorization: the single-channel source separation case

Jurnal Teknologi dan Sistem Komputer, 2021
The Short-time Fourier transform (STFT) is a popular time-frequency representation in many source separation problems. In this work, the sampled and discretized version of Discrete Gabor Transform (DGT) is proposed to replace STFT within the single ...
