Header Chunk Size Error for Wav File

Question

I'am using these methos in order to read wav files: http://www.labbookpages.co.uk/audio/javaWavFiles.html

It give me an error at

WavFile wavFile = WavFile.openWavFile(file);

WavFileException: Header chunk size (48255020) does not match file size (48255020)

However it is not always, when I tried to use different wav files sometimes it is not causing any error.

Is it caused from the wav file or openWavFile method, and can I fix this without changing any WavFile codes.

Answer 1

The chunk size must be 8 bytes smaller than the file as the chunk size does not include the header. So in your example where these two sizes are the same, the file is 8 bytes too small.
