You can then set different Profile settings for each plot:
You can select one of the following three graph types by clicking
the corresponding tab. All three views of the measurement are
calculated from the same measured test signal:
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.
Impulse response
Shows the response over time of the loudspeaker to a click. The
curve shows a maximum just after time zero, and then decays
rapidly depending on the amount of reverberation in the room. Any
additional peaks in the response indicate resonances set up by the
initial impulse.
