all my waterfall plots look like this one

[asylum]

There doesn't seem to be any of the decay information as i've seen on other plots here- even if i move the mic it still has this look -
all help appreciated

Waterfall plots are only meaningful for low frequency information.

Switch your axis to the standard used at HTS of:

Vertical = 45dB-105dB
Horizontal = 15Hz-200Hz
