FULL BAND DENOISING OF ROOM IMPULSE RESPONSE IN THE WAVELET DOMAIN WITH DICTIONARY LEARNING

Conventional wavelet-domain methods for room impulse response denoising rely on thresholding detail coefficients, which is unsuited for low frequencies. In this work, we introduce a wavelet-based post-processing algorithm that extends denoising to approximation coefficients by means of sparse dictio…
