AW: OT: VST plugin to do balance/pan function
Title:
Hey os,
I'd like to
come back to your offer below...short
answer: I need it for Windows.
Long answer: please find enclosed a reqspec for the
thing.
Thanks,
Rainer
Requirement specification for
a VST plugin for Windows XP platforms which allows for panning of mono sources
and “balancing” of stereo sources, in the following called
„panner“
|
001 |
The panner shall be
implemented as a VST plugin for Windows XP platforms as a stereo in/stereo
out device and shall be able to function with common bit depths and sample
rates up to 32bit/96kHz. |
|
002 |
The panner shall have at
least one control (“panpot”). |
|
002a |
The panpot shall provide
one real value to the panner ranging from -1…+1. 0 shall be defined as
“center position”. -1 shall be defined as “hard left”. +1 shall be defined
as “hard right”. This value shall be called
“p” |
|
003 |
The panner’s controls
shall be controllable within Ableton Live by MIDI commands. |
|
004 |
The panner shall
function as a 2 in, 2 out mixer which sends a combination of the two
channels of the stereo input pair (IL and IR) to the two channels of the
stereo output pair (OL and OR) defined by a mathematical
transformation. |
|
005 |
The mathematical
transformation shall be of the form
OL = IL*f(p) +
IR*g(p)
OR = IL*f(-p)) +
IR*g(-p)
with f, g real functions
of p. |
|
006 |
There shall be at least
one choice of function pairs f, g. |
|
007 |
There shall be one
choice of functions f, g as follows:
f = 1 ; p <
0
f = 1-p ;
otherwise.
g =
1-f. |
|
008 |
If the number of
function pairs is greater than one, there shall be a control for selecting
the function. |
|
009 |
If the selected
functions f,g are continuous, changing p may not lead to signal
artifacts. |
|
010 |
The panner shall be
optimized for resource-friendlyness, i.e. it shall not tax the host
computer’s CPU or main memory more than
necessary. |
