Hi,
This error of “File could not be read due to an unexpected error. Reason: Error in WAV file. No 'data' chunk marker” could be caused by the .wav file not abiding by the standardized format. The function 'audioread' relies on Windows Media Foundation WMF and can only read the standard format.
The workaround requires editing the bytes of the wav file. The following code helps in deleting the extra bytes and converting the .wav file to the standard format:
>> loc = strfind( bytes.', uint8('data') ); % Find where the 'data' keyword is.
>> bytes( 37:loc-1 ) = []; % Delete the extra bytes.
>> f = fopen( 'tmp.wav', 'w' );
>> fwrite( f, bytes, '*uint8' ); % Write the new byte sequence.
>> fclose( f );
>> [y, Fs] = audioread( 'tmp.wav' ); % Read the audio file.
WMF expects bytes 37-40 to store the keyword 'data', so the extra bytes between 37 and the first byte of the keyword need to be deleted.
I hope the above workaround solves the issue. If it does not, may I please know the MATLAB version you are using?
Thanks,
Keerthana
