[[EMAIL PROTECTED]]

Hi,
I want to build equalizer (I mean to the equalizer bars..) I want to
build a VI in LabView 7.0 and is job will be like that:
Show the bars of the equalizer moves by the music rate.. The music
will be the music thats plays in the computer in the time that the VI
runs. Someone told me that I should do it by finding the high Bases is
that right?

                 Thanks,
                 Reiss Rotem
