For doing audio analysis, we have found that a spectrum analysis program
for the PC works much better than even high-end oscilloscopes (Tektronix
or Yokogawa). These programs have much more flexibility in terms of
display settings, and the students can save/print the results. We have
used the commercial package SpectraPlus. However, there are many
freeware spectrum analyzer programs for the PC and Mac. For example,
while I have not played with it extensively, the program VisualAnalyzer
(http://www.sillanumsoft.org/download.htm) seems to be a fairly
full-featured program.
