Hi.  I started my electrical engineering coursework at Iowa State 
University 44 years ago.  The tools have changed a lot!

I would encourage you to check out the vOICe, because it may be useful in 
some situations.  It can sonify practically anything you can put onto a 
Windows PC, as long as the images are stationary or change slowly.  This 
includes a function for sonifying the active window or the area around your 
mouse pointer.  Do some of your ear training with a webcam, since you can 
quickly present various images to it.  Stereo headphones are a must, also, 
because the left-right panning can help you determine where various sounds 
occur on the image.  The vOICe software is a tiny executable (as Windows 
programs go) and has controls for adjusting zoom, contrast, scan rate, and 
even the number of frequencies into which the vertical dimension of the 
soundscape is mapped.  Dr. Meiger, who wrote this software starting nearly 
20 years ago, is quite expert in psychoacoustics.  He has examples showing 
how images can be sonified, then converted back to images in a spectrogram 
fashion, with some loss of fidelity.

Having said all this, I don't use this software on a daily basis.
