Please can you help.
What I'd like to do is this:
Have a directshow filter that can plug in anywhere in a filtergraph and port the instantaneous peak volume level to vb, so I can make a vu meter in visual basic.
I understand you cannot do this in vb alone, so, perhaps with some help, I can make a dll in C to "talk" to vb to do just this.
Im not too worried about the graphical interface of the meter (I can do tis in vb) but i somehow need to have a number that is updated regularly to reflect the changes in the peak (or rms) level of the audio stream.
Any ideas/sample code etc?
Or am i going about this all wrong?
Perhaps there`s an easier way!
Thanks for reading my post
