"Just want to thank you for setting up the order form so it can be used to calculate without actually ordering. It is SO refreshing to be able to estimate the cost of a service without having to register and log in and accept cookies and all that nonsense. In fact, I often leave a site if I have to go through all that just to find out my costs. ..."

Companding

A combination of a compressor at one point in a communication path for reducing the volume range of signals, followed by an expander at another point for restoring the original volume range. Usually its purpose is to improve the ratio of the signal to the interference entering in the path between the compressor and expander.
