first this is my first post on this forum and im from Germany, so sorry for some confused language syntax ;-)
I developed a electric circuit that controls some LEDs. This is built into my computer to make some light effects. I wrote a controlprogramm for the microcontroler I used on the circuit board. So the Visual Basic Programm communicates with the microcontroler on the circuit board. I'm able to change some settings and so on... ocer the RS232. This works excellent!
Now I want to expand my software. I like to make an audio-depended effect show. Let me explain:
I have 6 colors (green, blue, red, yellow, white and uv).
I need a source or tip that says me what frequenz at the moment is and how high the level is.
So that I can program: Red LED light up at 100Hz (and maybe 75% audio level) How this information is send to the microcontroller is no problem.
My problem is to scan the soundoutput and get the current frequenz and the audio level.
Any idea to solve or help me a litte bit?
Thanks in advantage and sorry for some confused language.
