could it just be that a lot is lost between what he's trying to say and what you think he said? because I have a hard time imagining a math professor saying something along the lines of: sound has only one dimension. even considering a punctual source or punctual recording position, we're still very much getting amplitude over time.
just here to contradict myself like a boss. amplitude over time is actually a one dimensional signal. Saratoga is right and reading his post got the me from more than 20 years ago instantly punching today's me in the face. I first went for a 2 dimensions space for the graph showing a signal, but time is the only independent variable in the function.
sorry math guy, sorry younger me. I'm a fool who forgot all his math.
Also, the Fourier transform can be used to convert audio data to a frequency domain representation, which is a 2D array of frequency bins that vary in intensity over time, so in that sense audio could be considered 2D.
The FFT of a signal returns a function which itself returns a two-dimensinal value for each input component. It is therefore one-dimensional as well.

People, don't know if I'm dumb or just uneducated but I can not figure out how to create a playlist from Foobar2000. The library is there and I can select and play a song but creating a playlist eludes me.
