audio cutter in matlab

Hi,

I have loaded an audio-file of 8sec's using 'wavread' function.

I have to cut it to say 1sec file.

i know that it can be done by taking only few samples outof total samples.

but how can i do it interms of seconds,i.e,i have to get only 1sec audio file from 8sec audio

file

how to do it matlab?

is there any simple inbuilt function.

Hope wavwrite could help your question? I am not sure about my answer

You can do something like this: If 1 second removed from end:

[Y,FS,NBITS] = wavread('file.wav');  % Your file name
num_samp = round(FS); % Number of samples in a sec
wavwrite(Y(1:end-numsamp), FS,NBITS,'new_file.wav'); % if 1 second removed from end

IF 1 second removed from beginning

   [Y,FS,NBITS] = wavread('file.wav');  % Your file name
    num_samp = round(FS); % Number of samples in a sec
    wavwrite(Y(numsamp+1:end), FS,NBITS,'new_file.wav');

[x,fs]=audioread('C:\Users\Satyam\Downloads\Music\record20171119115236.wav');
z=zeros(fs*1,40); % for 1 second
h=1;
for j=1:40;
  for i=1:(fs*1);
      z(i,j)=x(h);
      h=h+1;
  end
end

    [x,fs]=audioread('C:\Users\Satyam\Downloads\Music\record20171119115236.wav');
     x=resample(1,fs);
     audiowrite('newfile.wav',x,fs)

resample needs 3 parameters to work
