> Its comparing 1 dimensional space to 2 demential space

Although I love the coinage "2 demential space", I think you mean "comparing one-dimensional space [audio] to three-dimensional space [video]". A two-dimensional signal might be a still image or a temporal sequence of samples from a one-dimensional array of sensors, such as those in a single slice of a CT machine or a linear MIMO antenna array. A video signal is three-dimensional, not two-dimensional, and probably not "2 demential" either.

Including pixel intensity, you are correct. Infact it has thee planes, so you could even call it 9 demential If you break it down that way.

No, wavelength is just one more dimension along which intensity may vary (in addition to X, and Y, and time), not five or six more dimensions, so a multi-band image is only three-dimensional, regardless of whether there are three wavelength bands (like RGB or YCbCr), four (like RGBA), 8 (like Landsat), or 210 (like HYDICE, AVIRIS, and other imaging spectrometers).

My point is, I am comparing temporal dimension to temporal dimension regardless of how many special dimensions there are. And I don’t understand the argument that an audio sample is more analogous to a pixel that it is a frame on a time line.
