Deconvolution
https://www.dspguide.com/ch17/2.htm
To extract the original signal, the deconvolution filter must undo these amplitude and phase changes. For example, if the convolution changes a sinusoid's amplitude by 0.5 with a 30 degree phase shift, the deconvolution filter must amplify the sinusoid by 2.0 with a …

Noise in audio is always uncorrelated statistically to the clean signal. This is the principle upon which the Wiener filter works. Figure 11.3 gives an example of deconvolution in block diagram form that should suffice to solve your application in audio. A real Wiener filter minimizes the MMSE ratio as defined in 11.37.

Deconvolution using Wiener filter (i.e. Tikhonov with µ=1/SNR) Noise is destructive away from focus (4DOFs) Utilized a priori knowledge of depth of each digit Artifacts due primarily to noise getting amplified by the inverse filter Deconvolution in the presence of noise SNR=10.

noise in audio deconvolution result - Signal Processing ...
https://dsp.stackexchange.com/questions/36453/noise-in-audio-deconvolution-result
I'm testing some code to perform deconvolution of two audio signals to recover the impulse response. Presently, as part of testing, I am simply deconvovolving two identical signals. I have the assumption that I should be able to recover a simple dirac-delta impulse response from this, but for some reason, there is a lot of spurious noise in the ...
