how to calculate bit rate of audio signal in MATLAB?

 CompressionMethod: 'Uncompressed'
          NumChannels: 2
           SampleRate: 44100
         TotalSamples: 1264896
             Duration: 28.6824
            BitsPerSample: 16

audio signal is sampled at

[y,Fs]=wavread('x.wav');
file_read=resample(y,10,22050);
file_open=fopen('file_read','r');
a=roundn(file_read,-3);
byte_size_of_sampled_signal=getByteSize(a);
b=zeros(1,2*length(a));
figure;
plot(a(:,1));
title('input sampled sequence');

Answer 1

[Walter Roberson]

bitrate_per_channel = SampleRate * BitsPerSample

multiply by the number of channels if you want to know the bit rate for both channels combined.

thank you sir...

[y,Fs]=wavread('x.wav');
file_read=resample(y,10,22050);
file_open=fopen('file_read','r');
a=roundn(file_read,-3);
byte_size_of_sampled_signal=getByteSize(a);
b=zeros(1,2*length(a));
figure;
plot(a(:,1));
title('input sampled sequence');

Could you point out which part of this code calculates the bit rate?

Could you clarify why you choose to open a file named file_read for reading, even though you never read from the file and you do not close the file either?
