LPC & Sound: Filter (inverse)

A command that creates a new Sound object from one Sound and one LPC object which have been selected together.

Behaviour

Given a filter (the selected LPC) and its output (the selected Sound), its input is reconstructed (the new Sound that will appear in the List of objects).

In Z-domain notation: E(z) = O(z) / H(z), where O(z) is the filter output Sound, H(z) the LPC filter, and, E(z) the filter input Sound. (Selecting this newly generated Sound and the LPC, choosing the command Filter... generates a Sound that is identical to the Sound that originated the LPC.)
