Hi,

I am an engineering student and I have to submit a DSP project during this month.
Can you please help me to guide how to create it?
My project title is "Speech Denoising based on Spectrum Substraction".
Thanks for your help and your time.

Regards,
ZMH
 

The idea is to estimate the spectral magnitude of noise using noise match filter, and making use of the fact that power spectra of additive independent signals are also additive and that this property is approximately true for short-time estimates as well. Hence, in the case of stationary noise, it suffices to subtract the mean noise power to obtain a least squares estimate of the power spectrum
