Signal Processing

Proposed Q&A site for practitioners of the art and science of signal processing.

Can you define the audience better than "anyone?" Also... the audience is not the description. The description will be inferred by the example questions. – Joel Spolsky♦ Jun 2 at 1:07

Seems a bit narrow. – Robert Harvey Jun 2 at 5:11

I would add Image Processing under this forum. It will draw more attention at the beginning. If it gets too crowded then it might be split. – Drazick Jun 23 at 6:01

Definitely include image processing and higher dimensional data sets. Often the same theory used for 1D apply to rows and columns in 2D, or along the temporal dimension. But image processing is covered in other places too. I see the difference as here being engineering, math theory, implementation in hardware, DSP vs. practitioners in music production, photography, astronomy etc. – DarenW Aug 3 at 3:54

Apparently code is OK on this site. Every other proposal is being very strict about confining such questions to StackOverflow. – Robert Harvey Jun 3 at 3:19

This one comes up regularly on SO and other forums. Usually the person asking the question thinks that they just need "an FFT", and so need further need explanations of windowing, calculating log magnitude, time/frequency resolution, etc. – Paul R Jun 15 at 16:25
