Joe,

Too high an audio level will cause the FFT results to spill into 
adjacent frequency bins and widen the trace on the screen. Simply 
backing off the input level to Argo (or whatever program you use), will 
thin out the lines and reduce background noise. BUT, you might lose the 
trace altogether in a fade, so it's reasonable to let things bloom out a 
bit on the signal peaks.
