Sound Pre-Processing

There are available devices, some inside microphones, other go between the microphone and the radio, which can change the signals sent from the microphone to the radio. This then changes how those signals are heard. These effects can be things like adding echo or re-verb to the sound. While these effects can be fun (while others find them annoying), they do not help with the use of the radios, and again they are not included in the license.
