How to extract info from a .wav file?

Does anyone know how to extract data from a .wav file.
I dl a trial version of a program to convert an mp3 to
a wave file. But after the 30th time it adds some stuff
to the file that I don't want. And I need to know how to
get rid of it. Any suggestions would be appreciared.

Thanks

In the beginning of the file, there are 44 bytes, that tells you what length the file is, the frequency, bit sample rate, and channels. If the length doesn't match the files length, it will not work. The length is stored in two places, in &H100^x style so it's easy to retrieve them. The rest of the file doesn't matter what it contains, cuz it's 16bit or 8bit binary data which means all ascii are used.

kedaman,

I appreciate your response to my post. But could you show me how I can extract the data from a wave file. Get rid of what I don't need, and only keep what I do need.

Then you should open the wavfile in binary, get everything from the 45 byte into a string or byte array. Do you need code or something?

Yes I do need some code, if you wouldn't mind.

Thanks

Code:

---

    Open File$ For Binary As x#
        filebuffer$ = Space(LOF(x#) - 45)
        Get #x#, 45, filebuffer$
    Close #x
