Are there any good resources out there detailing Perlin noise generation? I understand that most languages have noise generating libraries available, but I'm interested in creating my own for fun/experience. I've already looked at this, which seems pretty popular, but it only gives an in-depth explanation of one dimensional noise. Google...
After watching the first game of the FIFA worldcup I was very annoyed by the sound of the Vuvuzelas. A theoretical question came up about filtering that noise out of the sound stream. What algorithms are needed to remove such a "constant" noise and is it possible to keep the quality of other background sounds? ...
So apparently if a Mysql table's fulltext index contains a keyword that appears in 50% of the data rows, that keyword will be ignored by the match query So if I have a table with the fulltext index 'content' which contains 50 entries and 27 of the entries contains the word 'computer' in the content field, and I run the query: SELECT *...
I have data of this form: for x=1, y is one of {1,4,6,7,9,18,16,19} for x=2, y is one of {1,5,7,4} for x=3, y is one of {2,6,4,8,2} .... for x=100, y is one of {2,7,89,4,5} Only one of the values in each set is the correct value, the rest is random noise. I know that the correct values describe a sinusoid function whose parameters a...
Hello, A lot of new Android applications I've been seeing are using a noise effect on their backgrounds, usually a gradient. What interesting is that some applications use radiel gradients throughout their application with this effect, which would require a lot of disk space for the images. Now Android has GradientDrawable which can cre...
I want to develop a small Android app to measure the current noise level (probablyin dB). But I have no idea what to look for in the libs. I don't want to record the noise. Can someone give me a pointer what classes to look at? ...
I'm looking to create a "blob" in a computationally fast manner. A blob here is defined as a collection of pixels that could be any shape, but all connected. Examples: .ooo.... ..oooo.. ....oo.. .oooooo. ..o..o.. ...ooooooooooooooooooo... ..........oooo.......oo.. .....ooooooo..........o.. .....oo.................. ...
I have tried so many different strategies to get a usable noise function and none of them work. So, how do you implement perlin noise on an ATI graphics card in GLSL? Here are the methods I have tried: I have tried putting the permutation and gradient data into a GL_RGBA 1D texture and calling the texture1D function. However, one call t...
Hello, I would like to know if it's possible to disable the noise reduction microphone via code. My app plays background music that gets trim off because of this new mic. So i would like to have the background noise mic disabled while my app is open and running. Thank you ...
Hi, I'm writing a little software synthesizer and it sounds pretty decent except for a slight noise when the volume changes. e.g. while the volume is changing, a sine wave sounds more like a flute, when the volume is constant it sounds bright and pure. As the volume changes pretty much constantly because of the ADSR, this is very annoyin...
