SoX in cmd - A little help Options

[FreaqyFrequency]

I should begin with the disclaimer that I am completely a noob at cmd. In fact, I only recently got acquainted with it in order to experiment with lossyWAV, and I still have much learning to do.

I'm trying to set up an ABX experiment to see whether or not files resampled to 32k via SoX' VHQ linear phase algorithm are transparent. If they are, this would mean that I could be comfortable resampling all of my lossless content to 32k (consequently saving a lot of space) and then converting to Vorbis, hopefully maximizing the efficiency of its psychoacoustic engine. After I downloaded the binary and moved the executable file to my output folder, however, cmd is not recognizing its presence at all. Could anyone lend me a hand there, first of all, and then help me with the parameters for resampling (if further help is necessary)?

Thanks in advance.
