Expected a string for the parameter name, instead the input type was 'double'. what to ?

% Setting variables

fs = 1000; % Sampling rate in Hz

bits = 8; % Bits per sample

channels = 1; % Number of channels: 1=mono

recObj = audiorecorder(fs, bits, channels);

% Collect a sample of your speech with a microphone and plot the signal data:

% Record voice for 2 seconds

%recObj = audiorecorder;

disp('Start speaking.')

recordblocking(recObj, 2);

disp('End of Recording.');

% Play back the recording

play(recObj);

% Store data in double-precision array

y = getaudiodata(recObj);

filename='sample01.wav';

% Plot the waveform

%figure;

%plot(myRecording)

%xlabel('time (milliseconds)')

%ylabel('amplitude')

% Converting audiorecorder object to wav

audiowrite(filename,y, fs,bits);
