	Using generated tones makes it easier to identify which parameters of the sound influences specific paramets of the resulting image. This can help in getting an idea how 'real world sounds' would look as an image.

	If you have multiple tones of different frequencies, you will hear interference. This interference is also visible in the pattern when you convert the audio to an image. Based on the frequencies the appearance of the pattern will change.		If you have multiple tones of different frequencies, you will hear interference.

	Another thing I need to find out is how to add color to the images. It is possible using noise as an input, but I haven't found out yet how to do it with tones generated in audacity. Adding a header with a color encoding indicator in imagemagick didn't work.		Another thing I need to find out is how to add color to the images.
