I was hoping to create a real time voice changer to either run on my computer or from a raspberry pi I own. Basically, I would speak into the microphone and then the sound would be played back in real time with special effects. I've searched stack overflow for a bit and found out how to do a robot voice by editing sine waves but I don't know a library to edit sine waves with. I'm on a windows 64 bit machine.
Thanks
EDIT: The question is, how would I go about editing sine waves from the microphone in realtime?

I am attempting to create a personal PC streaming application on Windows. I was wondering how I could grab data from an AMD GPUs display output in C++ 11 (somewhat like OBS)? I attempted this in java with Robot.createScreenCapture method but was not able to achieve sufficient speeds required for streaming. I hope this is clear enough. Anything helps, thanks.
AMD AMF SDK can get you this: Is there a functionality to capture screen directly and encode at GPU buffer memory?
amf\public\src\components\DisplayCapture already has code which is basically wrapping DD API into AMF component. If my memory serves me right DVR sample shows how to use it (source code definitely has traces that it was/is working).

I'm trying to display info from the Spotify API as a overlay for DirectX and OpenGL games as there is a lot of people asking for it and I needed a project for school. I've got all the design elements working in a Electron application and I now just need to make it an overlay.
The application has a couple states: Playing, Paused, Control (frees cursor to allow in game song control with a couple buttons), Connect(for when audio is played via Spotify connect rather then on the host pc) and Stopped.
If possible I would also like to have the control state toggle with a key bind.
I've had a look online and can't find anything helpful, but I do know that Discord uses something like this. From what I can see, they use C++.
Edit: pergy commented with this: electron offscreen rendering which seems good enough.

i am looking for a way to insert a video in my software developped in C++ using the gtkmm library. But i did not see any documentation on this.
Does someone know how to put a video with the GTKmm library ?
Thanks a lot !
gtkmm itself is not a multimedia framework. However, you can use it together with multimedia frameworks, e.g. GStreamer (or gstreamermm, which is c++ wrapper for GStreamer). Here is an example of simple multimedia player written in gtkmm and gstreamermm: https://git.gnome.org/browse/gstreamermm/tree/examples/ogg_player_gtkmm

I'm having two mouses on my PC, and now I want to get their positions at the same time. Can I do this through programming?
Thanks!
In Windows you cant, because you can only get the Position of the Cursor which is controlled by every mice.
On Linux, it's definitely possible to control one cursor with two devices. For instance I have a touchscreen and a mouse, the most recent one to be used moves the cursor.
This Question talks about a package which allows 2 cursors on Ubuntu.

Well, I'm trying to do a small game for DS-DSi in C++. Just for fun and feel happy.
I was wondering if there is any guide or I could get some help with getting started. I have no clue how it works or how to make it boot on the DS.
Thanks~
I suggest getting a nds flash cart, like the cycloDS (for the DS) or an R4i (for the DSi). Thats how you can run your creations on the actual device.
Here is a good list of tutorials starting from the beginning (setting up your environment, getting the armKit etc) on DS development.
