i am working with a calculation that is sent wirelessly by sound (fsk modulated) now i want to recover that first recording that signal and then demodulation ,demodulation into digital waveform (i have done all mentioned stuff now ...) i want to convert this digital waveforn into binarydata stored in an array.(audio siganl is attached)

clc;
clear all;
close all;
fc=500;
fs=8000;
fDev=50;
t=0.1;0.001;0.5;
% b=audiorecorder; 
% recordblocking(b,3);
% a=getaudiodata(b);
% audiowrite('lala.wav',a,44100); %there is some issue in recording
y=audioread('lala.wav');
sound(y);% listen your audio input
z = fmdemod(y,fc,fs,fDev);
figure
plot(z);axis('tight');
wn=fc/fs;
s=fir1(50,wn,'low');
x=conv(s,z);
figure
plot(x);axis('tight');
%all starts here plz help!!
% mn=[];
% if(x>=20)     
%     j=1;
% else 
%     j=0;
%     end
% 
%   mn=[mn j];
% disp(' Binary information at Reciver :'); %want this from all given data.
% disp(mn);
