Spectrum Analyzer Display in CVI

[CS Knurek]

Has anyone developed code that replicates a
'bar graph' display like those in home audio
equipment. I am looking to display points in
an X-Y or bar graph that hold their maximum
amplitude until a set time or threshold.
Thanx

Here is a link to an example written for CVI that uses a National Instruments DSA board to acquire signals and gives a spectrum analysis in a graph. You may not have the type of board the program was meant to be used with, but you can still use it as a guide for writing your own application.

Jason-

Is ths CVI example of an audio spectrum analyzer still available?

I tried the link you posted (see below) and it appears to no longer be viable.
