I need a dll function for calculating the beats per minute where the path of the file gets fed into the function. The dll can be done in C++ but must be interfaced with Visual Basic.
I want a dll and the source code in Visual Basic that calulates the beats per minute of MP3's. It must be simple enough so I just have to know the path and it will return the beats per minute so I can save the information in any format I want. It must be reasonably accurate in all situations.
