Getting Frequencies

Hi!
Someone know, or have vb net code,
how to get the values of audio frequecies ( 30, 60, 80, 90, ...., 8000, 12000, 16000 )
from master volume channel of windows?
thanks

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.

i need to get, to extract, peaks frequencies, from master volume channel
like you can see in this example PeakMeter but i need vb net code

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?

yes, right, i would make a my own Graphic EQ, but i can't find vb net code for it,
i just need for the values of the peaks the other i can do by myself
