Maybe you can convert the C/C++ code here to C#: http://www.firstpr.com.au/dsp/pink-noise/ The easiest way to get sound to the sound card is to generate a wav (spit out some hardcoded headers and then sample data). Then you can play the .wav file.
Create video and audio noise, artifacts, and errors with ffmpeg Noise Using filters The geq (video “generic equation”) filter (with nullsrc as its “blank canvas”) can create video noise, and the aevalsrc filter can create white noise audio: ffmpeg -f lavfi -i nullsrc=s=1280×720 -filter_complex \ “geq=random(1)*255:128:128;aevalsrc=-2+random(0)” \ -t 5 output.mkv Note that this will create … Read more
The Random class is designed to be a low overhead source of pseudo-random numbers. But the consequence of the “low overhead” implementation is that the number stream has properties that are a long way off perfect … from a statistical perspective. You have encountered one of the imperfections. Random is documented as being a Linear … Read more
Intresting task. Lets try to simplify it – lets resolve this concrete case Solution Working version is here: https://github.com/amuzalevskiy/perlin-landscape (changes https://github.com/jorgt/perlin-landscape/pull/1 ) Explanation First what came into mind is: Just two steps: find an vertical column, which matches some set of tiles iterate tiles in set from bottom to top, checking if cursor is placed … Read more
TL;DR, see the code and picture at the bottom. I think a Kalman filter could work quite well in your application, but it will require a little more thinking about the dynamics/physics of the kite. I would strongly recommend reading this webpage. I have no connection to, or knowledge of the author, but I spent … Read more
For very simple pseudorandom-looking stuff, I use this oneliner that I found on the internet somewhere: float rand(vec2 co){ return fract(sin(dot(co, vec2(12.9898, 78.233))) * 43758.5453); } You can also generate a noise texture using whatever PRNG you like, then upload this in the normal fashion and sample the values in your shader; I can dig … Read more
