Processors are anything that create or manipulate messages. They are configured in the `processors` property of an individual [route](/concepts/routes). Processors have the ability to change the type of the message flowing through the system so a byte array can come into a `osc.message.decode` processor and a OSC message type will come out of the processor.

## YAML Definition

A processor YAML block has the following properties

- **id**: a unique identifier for the processor (auto generated when using the web interface)
- **type**: the processor type
- **params**: optional map for processor configuration values. The valid values will depend on the processor type
