Quadrophonic Matrix Encoder is a small, easy to use, simple audio encoder written in the Java programming language.
The technology developed and used in the 1970`s applies an encoding matrix to the four input channels LF (Left Front), RF, LB (Left Back) and RB to record them into 2 channels.
Playing back such an encoded recording by applying the correct decoding matrix brings back most of the original four channels (4:2:4 Encoding/Decoding).
