audio - Use MATLAB to Restore a Signal from a Given ...
https://dsp.stackexchange.com/questions/26433/use-matlab-to-restore-a-signal-from-a-given-degraded-signal-using-tikhonov-regul
Anyone could share how to develop an application in MATLAB to restore the signal from a given degraded signal using Tikhonov regularization i.e restoring the signal f via solving. min | | g − f ∘ h | | 2 + λ | | σ ∘ f | | 2. where σ = [ 1, − 1]. and ∘ denotes the circulant convolution operator. The setting of the value epsilon is dependent on the signal to noise ratio.

Matlab code for low pass filter (LPF) We import the audio signal into Matlab by executing the code below: % Program to implement a LPR(FIR) with cutoff 8kHz to denoise audio signal. [fileName, pathName] = uigetfile('*.*', 'select the input audio'); [x, Fs] = audioread(num2str(fileName)); % x is the audio samples and Fs is the sampling rate.
De-Noising Audio using Spectral Subtraction in MATLAB …
https://blogflylogical.wordpress.com/2020/07/29/de-noising-audio-using-spectral-subtraction-in-matlab-and-ableton-live/
Last time I wrote about audio restoration using simple digital filtering (in MATLAB and Ableton Live). I’ve since received another old Havering recording from Walt.Again from an old cassette tape, this recording is rather noisy. In this post, I explain how I cleaned it up using a more elaborate technique than previously.

MATLAB supports sound acquisition and generation using Data Acquisition Toolbox. This MATLAB code example shows you to acquire two seconds of audio data from a sound card, calculate the frequency components, and plot the results. Use the "Save and Publish to HTML" button in the MATLAB Editor to execute this example and automatically generate a …
MATLAB code of Audio Denoising Using Hard and Soft Threshold
https://www.matlabclass.com/2019/02/matlab-code-of-audio-denoising-using.html
MATLAB code of Audio Denoising Using Hard and Soft Threshold. Noises present in communication channels are disturbing and the recovery of the original signals from the path without any noise is very difficult task. This is achieved by denoising techniques that remove noises from a digital signal. Many denoising technique have been proposed for the removal of …

Create a WAVE file from the example file handel.mat, and read the file back into MATLAB®. Create a WAVE ( .wav) file in the current folder. load handel.mat filename = 'handel.wav' ; audiowrite (filename,y,Fs); clear y Fs. Read the data back into MATLAB using audioread. [y,Fs] = audioread ( 'handel.wav' ); Play the audio.
