%Hi everyone,
%This is my code it is working fine but I'm getting error. Why? and how can I fix it?
%One more question how can download the modified audio from MATLAB?
[y,Fs] = audioread('noisy2_group2.wav'); %read file from directory
[b,a] = butter(4, [0.015, 0.125], 'bandpass'); %Implement bandpass filter with specified frequency ranges
fOut = filter(b, a, y); %create the updated signal
sound(fOut,Fs) % play the sound signal and plot it
subplot(2,1,2), plot(y); %plot given signal
subplot(2,1,2), plot(fOut);
wav write(fOut , 16000, 'fOut') %Obtain the new signal

Perhaps you wanted wavwrite instead of wav write ?

Hi Abdullah,
I see that you're trying to filter an audio file and store the filtered audio signal in a new file. wavwrite is a legacy function which is removed from MATLAB 2015b. Instead, You may make use of audiowrite function as an alternate to write audio signal.
Following is a code reference for the same:
% Syntax for audiowrite is audiowrite(filename, audioSignal, bitRate)
audiowrite('new_signal.wav' , fOut, 16000); %Obtain the new signal
Also in the Sample Code in question, both y and fOut are plotted in the same subplot. i.e subplot(2,1,2). Instead, You may try to use both upper and lower portions of the plot as follows:
subplot(2,1,1), plot(y);
subplot(2,1,2), plot(fOut);
For more details on how to use sub plots, You may refer to subplot
