i want to use a zoom h4n recorder as a usb interface to make a waterfall plot of ambient noise. the plot should have time as the x axis,
noise frequency as the y axis, and intensity shown by colour.
the h4n gives 24 bit wav files.
expesnive data acquisition systems can achieve this but are tricky to set up and use, and not often easily portable.
so does anyone know if there is a software already exists that would do this, or how hard it would be to develop the software?
