Waterfall displays a 3 dimensional color frequency graph. The horizontal axis is frequency in Hertz (Hz), the vertical axis is magnitude in decibels (dB). The upward scrolling of the graph is time.
| Waterfall Settings | |
|---|---|
| Setting | Description |
| Automatic full frequency range | Automatically sets the frequency (vertical) axis range to match the current sampling rate of the file. For a sampling rate of 44100Hz the range is set from 0 to 22050Hz (the Nyquist rate). |
| Fixed frequency range | Allows the frequency (vertical) axis range to be set manually, giving more frequency detail within that range. |

From (Hz), To (Hz) |
Sets the frequency range when Fixed frequency range is selected. |
| Axis | Shows numbers on the horizontal axis. |
| Grid | Draws grid lines on the graph. |
| Fade | Fades the graph as it scrolls to the back. |
| Logarithmic | Changes the frequency (horizontal) axis from linear to logarithmic. |
| 1 second dark transparent walls | Draws a dim transparent rectangle every second, dividing the graph into 1 second sections. |
| Height (%) | Changes the vertical height of the graph with respect to the height of the visual's window. A value of 50% makes the maximum, peak magnitude height half as high as the window. |
| Scroll angle | Change the vertical scrolling angle. 90° scrolls straight up. |
