hould be:
11) [ady] = [ady] - absolute value of [base] * [adx]
<p>Also, the parameter order of render_point(x0,x1,y0,y1,X) and render_line(x0,
y0, x1, y1, v) is not consistent, and the references to the render_line
function use different ordering:
- Floor 1 / curve computation / step 2: curve synthesis
8) render_line( [lx], [hx], [ly], [hy], [floor] )
12) render_line( [hx], [hy], [n], [hy], [floor] )...

...orks as follows:
At the beginning Y[0] and Y[1] contain the absolute amplitudes (log scale)
at the lower resp. upper X boundaries, and the Y[i] for i>=2 are the
wrapped difference values, which are then progressively replaced by the
predicted absolute amplitudes at X[i]. In the current spec docs
render_point always takes its input from [floor1_Y] (which mostly contains
differences) and [predicted] then is output into [floor1_final_Y], without
any feedback. IMHO this doesn't work out.
Either the distinction between [floor1_Y] and [floor1_final_Y] has to go
away, otherwise the following may do the tr...

...or 1 / curve computation / step 2:
It is confusing that these steps are using a different parameter
order for calling the same function:
8) render_line( [lx], [hx], [ly], [hy], [floor] )
12) render_line( [hx], [hy], [n], [hy], [floor] )
As well as the definitions of the functions render_line
and render_point:
render_line(x0, y0, x1, y1, v)
render_point(x0, x1, y0, y1, X)
