AUDIO DENOISING USING WAVELET TRANSFORM
https://www.ijaet.org/media/0005/44I6-IJAET0612696.pdf
In denoising of the audio signals, the denoised signal obtained after performing wavelet transformation is not totally free from noise, some residue of noise left or some other kinds of noise gets introduced by the transformation that is present in the output signal.
