Hi Matthew,

If I know it correctly, you need to use overlapping windows of data, each of which will be windowed with a Hamming window or so to avoid Gibbs ringing. The fourier transform of these windows will then be put into columns and the resulting matrix will be displayed.

If you have not already, you may want to google short-time fourier transform [STFT] in the context of speech processing.

Best.
