A time-frequency transform decomposes the audio signaly over a family of time-frequency atoms{gl,k}l,k where l and k are the time and frequency (or scale) localization indices. The resulting coefficients shall be written: Y[l,k] = hy,g l,ki = NX−1 n=0 y[n]g∗ [n] . where ∗ denotes the conjugate. These transforms define a complete an d often redundant signal represen-

Abstract. Removing noise from audio signals requires a nondiagonal processing of time-frequency coefficients to avoid producing ldquomusical noise.rdquo State of the art algorithms perform a parameterized filtering of spectrogram coefficients with empirically fixed parameters. A block thresholding estimation procedure is introduced, which adjusts all parameters adaptively …
