@rob - here is sqrt taper example, maybe it will clarify some things:
float balance = Clip02(balanceKnob+1.f);//assume -1 +1 balanceKnob range - clip internal range to 0-2 to prevent user-error i.e. sqrt(negative number) = NaN
if (balance <= 1.f)
{
LevelLeft = 1.f;
LevelRight = sqrtf(balance);
}
else
{
LevelLeft = sqrtf(1.f-(balance - 1.f));//subtract 1 to get in 0-1 range
LevelRight = 1.f;
}
Edit: Here is the panning version (from my Stereo panning module that I'm coding today  ):
if (pan >= 0.f)//pan in -1 +1 range inernally
{
Left = inputL * sqrtf(1.f-pan);//lower side
Right = inputR + inputL * sqrtf(pan);//blend side
}
else
{
Left = inputL + inputR * sqrtf(-pan);
Right = inputR * sqrtf(1.f+pan);
}
Note: in the balance I'm switching/branching only the Left/Right Levels, in the pan version I'm branching everything.
Cheers

After checking it out, that taylor sin/cos approximation is a bit too inaccurate for the range it is used(0 to PI/2), here is my new version:
float taylorSin (float x)
{
float x2 = x*x;
return (1.f/5040.f)*x*(x2*(x2*(42.0f-1.0f*x2)-840.0f)+5040.0f);
}
float taylorCos(float x)
{
float x2 = x*x;
return (1.f/720.f)*(x2*(x2*(30.0f-1.0f*x2)-360.0f)+720.0f);
}

@rob - I can add a Stereo Balance Control module to my pack if you don't have enough time on your hands, just give me a shout.

Hey Andrew, time is indeed a problem for me atm. Sure, add the balance module to your pack.
My vacation starts soon tho!

ps: I got Daz his complete SDK2 sourcecode, he kindly donated all to be converted. There is also some OpenGL stuff, declined that for now. Now I all need is more time.  |

Not on vacation but got a deadline myself - end of this month, i.e. before my studies begin again. Looking forward to the ports of the Daz modules! |

Rob, is your intent to covert the DD modules to 64 bit?

Yes, it sure is.
He made a lot of modules in SDK2, so don’t expect anything very soon.

@ andrew, @ admin, @ twoifbysea, @ grinderone,
hola a todos, soy nuevo en desarrollo (soy un técnico de sonido), sé que el tema es antiguo pero tal vez pueda arrojar un poco de luz y dar información a otros usuarios que como yo, las matemáticas van,
explicó jejeje de una manera simple, panorámica SIEMPRE es una señal monofónica (no L y no R), imagina que en el mezclador tienes varias señales de entrada y quieres enviarlas y mezclarlas un solo canal llamado maestro, cuando se mezclan instrumentos reales, casi todos serán señales monofónicas (micrófonos, instrumentos de cuerda ...) que se envían a un canal estereofónico (maestro).
más tarde, el productor le dice que la trompeta quiere que se escuche más en el canal R del maestro, y eso es lo que hace la panorámica, tiene una entrada y dos salidas y dirige la señal más hacia un canal u otro (el módulo x -mix de jeff es una panorámica perfecta (Pan).
Balanced es SIEMPRE una señal estereofónica
ahora preste atención a Master, cuando levante la trompeta solo para R
descompensada Master haciendo que R suene más alto que L, y aquí viene el balance
El Balance modifica el volumen de un canal que deja el otro intacto, puede ser de un solo botón que alimenta solo un canal (nunca corta) o en dos volúmenes independientes
los dos controles deslizantes del maestro de un mezclador son realmente un equilibrio (contenedor con dos entradas y dos salidas, usted ingresa dos vca conectados a los controles deslizantes (o mando) y parchea la entrada L a una vca para dar salida a L, y la entrada R a otra vca para generar R, tan simple es un balance, si se ajusta el control deslizante de 0 a 13 y vca a decibelios, se obtiene el ejemplo de mezclador maestro
