can anybody help me turn this into real-time (max 1 second delay) continuous stream of input process output?

fs = 40000; % sampling rate fnyquist = fs/2; % Nyquist frequency duration = 256/40000 % time length of audio signal

recObj = audiorecorder(fs, 16, 1); % recObj is an audiorecorder with fs sampling rate, 16-bit depth and 1 (mono) channel % Record your voice for duration seconds disp('Start speaking.'); recordblocking(recObj, duration); disp('End of Recording.'); % play(recObj); % Recording playback y = getaudiodata(recObj); % Store data in double-precision array, y

% Frequency modulation fc = 10010; % Carrier frequency y = y(:); % ??? integratedy = cumsum( y ) / fs; % calculating integral of part of input signal Am = max(y); % calculating input max min amplitude t = ( 0 : numel( y ) - 1 )' / fs; % declare input's time axis dev = 9990; % Frequency deviation in modulated signal mody = Am*cos( 2 * pi * ( fc * t + dev * integratedy )); % Modulate. demody = fmdemod(mody,fc,fs,dev); % MATLAB built-in FM demodulation feature.

%% PLOTTING SECTION

subplot(3,2,1); % Plot the input audio samples (show time-domain demodulated signal) plot(y); xlabel('time by sample'); ylabel('Magnitude'); title('Time-domain input signal plot'); axis tight;

% Input signal frequency spectrum plotting: N = length(y); Y = abs(fft(y)); bin_vals = [0 : N-1]; fax_Hz = bin_vals*fs/N; N_2 = ceil(N/2); subplot(3,2,2); plot(fax_Hz(1:N_2), Y(1:N_2)); xlabel('Frequency (Hz)'); ylabel('Magnitude'); title('Single-sided Input signal magnitude spectrum (Hertz)'); axis tight;

subplot(3,2,3); % Show time-domain modulated signal plot(mody); xlabel('time by sample'); ylabel('Magnitude'); title('Time-domain modulated signal plot'); % axis tight;

% Modulated signal frequency spectrum plotting: N = length(mody); modY = abs(fft(mody)); bin_vals = [0 : N-1]; fax_Hz = bin_vals*fs/N; N_2 = ceil(N/2); subplot(3,2,4); plot(fax_Hz(1:N_2), modY(1:N_2)); xlabel('Frequency (Hz)'); ylabel('Magnitude'); title('Single-sided Frequency modulated input magnitude spectrum (Hertz)'); axis tight;

subplot(3,2,5); % Show time-domain demodulated signal plot(demody); xlabel('time by sample'); ylabel('Magnitude'); title('Time-domain demodulated signal plot'); axis tight;

% Demodulated signal frequency spectrum plotting: N = length(demody); demodY = abs(fft(demody)); bin_vals = [0 : N-1]; fax_Hz = bin_vals*fs/N; N_2 = ceil(N/2); subplot(3,2,6); plot(fax_Hz(1:N_2), demodY(1:N_2)); xlabel('Frequency (Hz)'); ylabel('Magnitude'); title('Single-sided Frequency demodulated input magnitude spectrum (Hertz)'); axis tight;

so when i run this, i can give input and hear the output in real-time, there is no much demand in the delay as long as this is done entirely in *.m files (no simulink or other).
