I am searching for a C# library to look where the sound of my output (speakers) is coming from. I think its called a spectrum analyzer? Does anybody know a good library?
thnx!
What usually you can do is have 3 or four mics facing each direction and then analyse the higher decibles or loudness and detect (resolve) direction
I think this article at CodeProject can help you getting started.
it has codes for processing wav files.
3D sounds like something common in gaming.

I can find plenty of methods for extracting all frames of a video when it is not playing. However what I want to achieve is extracting frames at runtime while the video plays. I want to be able to scan the video for qrcodes at runtime, but my blocker is extracting the frames while the video plays.
My platform for building this in is Windows and C#.
Looking for any library or strategy to achieve this. The best idea I have so far is have the video playing and extract and scan frames for each N second that the player progress hits. But there must be something better than that.
Maybe this tutorial made by Microsoft can help you a little bit.

Hope that my answer was helpful for you! :)
I want add machine sounds to my router table simulator program. The idea is to hear the stepper motors accelerate and decelerate with a change in pitch synced with my graphics. Same with the spindle motor, it has a pitch change as its rpm goes up and down. I thought of either adding real recorded motor sounds and modifying the pitch at run time or create synthetic sounds simulating the motors. Can anyone suggest the easiest way to achieve this? I have hardly any experience in sound programming besides the most basic stuff. I am programming in C# in Visual Studio.net

These should give an idea for the options (playing pre-recorded audio with some effects versus generating the sound synthetically) you mentioned, either way...
i am a 3rd year computer science student, and my seminar(graduation project) is in the next semester, so i started to think about it and i thought that a face recognition system would be a great idea, so i have two questions:
1- how can i read a picture programmatically, i mean if i have a picture, how can read the pixels and colors in order to recognize the face later on?
2- do you know any useful ebooks or resources that might help me in this topic cuzz i am really interested about it, and i hope that i can implement it.
thank you very much dudes
this is my first post and i hope you will really help me :)
Take a look at OpenCV which makes access to webcams easy! It can also help you with further picture computations.
Take a look at AForge.NET library. This library has very usefull API for computer vision. Take a look also on articles writen by author of this library - Andrew Kirillov. He wrote about motion detection algorithms and hand gesture recognition.
i have been searching for long in order to find how i can place a sphere/cube around my playfield so ill have an effect similar to sky. I have seen SkySpheres/Boxes but couldnt implement them . Im looking for a rather simple solution since my play field is really small and i just need something to replace the Clear(Color.Black) .I dont care about collision i just need it to be there with a texture on . Thanks !
You should take a look at Riemers XNA Tutorial
HERE is the post on the skybox.
can any one help me in detect moving objects in images and extract them out using c# ? i tried to extract them by subtracting image from previous image but this did't work with me
OpenCV is a good library to get started with this sort of thing. Be warned that it's not very well written, but the algorithms are there.
Motion detection is a very complex subject, and isn't related to C# that much. What exactly would you like to do? What are the "objects" in the video?
Do you want to detect any motion of anything, or motion of specific objects?
Can your application recognize the objects and differentiate them from the background?
