how to remove this error

??? Error using ==> fileparts at 17
Input must be a row vector of characters.

Error in ==> wavread>open_wav at 193
[pat,nam,ext] = fileparts(file);

Error in ==> wavread at 65
[fid,msg] = open_wav(file);

Error in ==> comparing at 10
z=wavread(record);

Error in ==> voice at 10
comparing(sample_freq);

my program is this

function[z]=comparing(sample_freq)
record_len = 2; %Record time length in seconds
open_lock='test';
sample_time = sample_freq * record_len;
disp('kindly speak to open the lock');
f = sprintf('%s.wav',open_lock);
input('Press enter when ready to record--> ');
record = wavrecord(sample_time, sample_freq); %Records the input through the sound card to the variable with specified sampling frequency
wavwrite(record, sample_freq, f);
z=wavread(record);
x=z;

can some one help me ,thanks alot

What version of matlab are you using? The last version of matlab that had wavrecord was R2013b. Time to upgrade?

Answer 1

[Walter Roberson]

z = wavread(f);

Answer 2

I suspect you want

z = wavread(f);

%and what's the point of x=z on the next line. Read the file as x directly if you must
%better use variable names that have meaning

The output of wavrecord is not a file name, so I don't understand why you tried to pass to wavread.

Note that wavrecord has not been part of matlab since R2014a.
