**SQRT**I/O calculates the square root of each sample of the source's data.

The typical application of the SQRT I/O is to use it as part of larger, more complex mathematical operations.

**Hint**: The SQRT-I/O can be used to calculate

**RMS**values. Perform the following steps:

- Create a Multiply/Divide
- Create a Resampler, set its Method to
*Average*and its Out/In ratio to output 1 sample - Create a
**SQRT** - Drag your source onto the Multiply/Divide twice to calculate squared values of the source's data.
- Drag the Multiply/Divide onto the Resampler to calculate a running mean of the squares.
- Drag the Resampler onto the SQRT to get the RMS values.

## Common properties and actions

To control the behavior of the SQRT I/O, several properties and actions are available.
These can be accessed through a popup menu which is shown when the I/O is right clicked in the Object Tree.
The properties can also be accessed through its settings window which is shown when the I/O is double clicked in the Object Tree.
To open the Object tree, click the **Show object tree** button.

By default, the settings window only shows the most used settings.
When **Advanced** is ticked, the extended window with all settings is shown.
