-- As the envelope volume is 5 bit, I have fitted a curve to the not quite log shape in order
-- to produced all the required values.
-- (The first part of the curve is a bit steeper and the last bit is more linear than expected)
--
-- NOTE, this component uses LINEAR mixing of the three analogue channels, and is only
-- accurate for designs where the outputs are buffered and not simply wired together.
-- The ouput level is more complex in that case and requires a larger table.
