Waterfall plot
Shows the response of the room to a series of short sine wave
pulses of frequencies between 0 and 250Hz. It shows how the
response decays over time at each of those frequencies.
The ideal waterfall plot would have a smooth profile and decay
evenly to a low level within 0.5 to 0.8 seconds. Peaks or dips
in the waterfall plot indicate resonances or absorption at the
corresponding frequency. Ridges extending forwards in time
indicate reverberation at the corresponding frequency.
The room correction profile aims to identify the strongest
resonances and to reduce the decay time of each strong resonance
to the average decay time for the room.
To compare two measurements
The
Plot measurement
window allows you to display a particular
graph type for two different profiles, or show the effect of one
profile compared to the original uncorrected room.
• Choose the first profile to be compared from the
Profile
drop-
down list, or choose
Bypassed
to display the uncorrected
measurements for the channel.
• Choose the second profile to be compared from the
Second
graph
drop-down list.
The two graphs will be displayed one above the other on the
screen:
