dear people,
i am a university student from indonesia and now i am doing my practical work at one of electronics company in here. here i get kind of job which is given by my mentor to do denoising audio signal with wavelet transform. honestly i've never learned bout wavelet yet. anybody can help me. i am stil on the way to understad its theory anyway.
regards nadya

Nadya, If you have the Wavelet Toolbox, then all the code you likely need is available there.
See the reference material for wden for example.

Dear all, I need a help in understanding the wavelet denoising on speech signal enhancement, specially at first level detail coefficients thresholding. I used toolbox and found that the denoised speech spectrogram shows having some aliased frequency components. When I use my code to threshold the first detail coefficients (high frequency band), surprisingly some unwanted noise arise in the low frequency bands, but if I apply threshold only on 2nd,3rd.. levels detail coefficients, except 1st level, no such phenomena appears.I suspect that the reconstruction of 1st level detail coefficients is generating such aliased noise components in the low frequency band of spectrogram. Does any one agree with me and how to suppress these aliased components.
Thank you, Regards, Parna
