    Depends, getting stuff from the master volume varies on the OS if I remember correctly. Here is an example of an api that is used in Vista.

    Well there isn't any VB.Net code. As dday pointed out audio analysis is only available through a fairly nightmarish set of API functions. Why can't you use the PeakMeter control which you have detailed? It is, after all, designed for the exact purpose.

    So - you are trying to make a Graphic EQ - but one that doesnt function to actually alter the frequencies - one that is simply used for monitoring the output frequencies of the computers master out?
