I'm very new to all of this.
Right now I'm just trying to add a bunch of different noises to an input signal and see how they affect my signal.
This is the current output of my code:
signal,Fs = audioread('~/Documents/Methlab/sp03-0.wav'); %generate white noise from input signal [m,n] = size(signal); snr = input('SNR: '); power = input('Power[DbW] '); whitenoise = wgn(m,n,power) noiseSignal = addnoise(signal,noise,snr); %FILTER THE NOISE %filteredSignal = VSLMS(filter_size,ss_uper,ss_lower,input_file,iterations) subplot(2,2,1); plot(signal) title('Input signal') subplot(2,2,2); plot(noiseSignal) title('White noise and signal sum')
If it helps anyone, I'm using this
addnoise function to add the noise.
From what I understand if I change power and SNR the white noise should look different based on what I input right? What am I missing ?
I've tried a bunch of powers and SNR combinations. SNR being 0.0004 or 0.9 or power being 30 or 0.0003 had no effect on the signal output.
