hello
this is a bit vague.. what is the txt file for ? does it contains a list of the wav files names ?

hello again
so this script will read the txt file where you have a list of wav file names
then the loop will open the associated wav files and display the data
hope it helps
clc
clearvars
folder = pwd; % current folder
fullfnames = readcell('wav.txt'); % read txt files and store filenames in cells
nFiles=numel(fullfnames);
for iFile = 1:nFiles
fullfname = char(fullfnames(iFile));
[signal,fs]=audioread(fullfile(folder,fullfname)); %read in wav
h = plot(signal); %
hold on
end

hello again
fullfile is used to create an absolute complete path to the files
I you work only on the current folder , this may be overkill but it's a safer method to create the path to your wav files
see more info on : help fullfile
