Denoising Audio Signal from Various ... - MATLAB & …
https://www.mathworks.com/matlabcentral/fileexchange/57533-denoising-audio-signal-from-various-realistic-noise-using-wavelet-transform
One of the transform technique known as wavelet transform will be used for denoising an audio signal from realistic noise. Predominantly, the objective of this proposed research is to characterise discrete wavelet transform (DWT) towards denoising a one dimensional audio signal from common realistic noise.

The denoised audio is converted back to the time domain using the output magnitude spectrum and the phase of the noisy signal [ 2 ]. You transform the audio to the frequency domain using the Short-Time Fourier transform (STFT), with a window length of 256 samples, an overlap of 75%, and a Hamming window.

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.
Vuvuzela sound denoising algorithm - MATLAB & Simulink
https://www.mathworks.com/matlabcentral/fileexchange/27912-vuvuzela-sound-denoising-algorithm
The sound denoising algorithm is based on the popular spectral subtraction technique. Based on the spectrum of the vuvuzela sound, this denoising technique simply computes an antenuation map in the time-frequency domain. Then, the audio signal is restored by computing the inverse STFT. See [1-3] for more detail about the algorithm.

The “Noisy signal” (blue) in the upper plot corresponds to abs(X_in). The “Noise model” (red) corresponds to Mag2Subtract. The “De-noised signal” (green) in the lower plot corresponds to mag_X_out. It has the value zero whenever the “Noisy signal” is below the level of the “Noise model”.

f would be the signal read into MATLAB while fs is the sampling frequency of your signal. f here is a 2D matrix. The first column is the left channel while the second is the right channel. In general, the total number of channels in your audio file is denoted by the total number of columns in this matrix read in through audioread. Step #2
