xrouting info

Russ · Jul 16, 2005, 07:06 PM

I thought I would post some info on how the signals are mixed within xrouting for anyone interested. This is based on the microcode used by xrouting with my sound card (10K1 based SB0228). I am not sure about 10K2 based cards.

The Recording Levels are the sliders in kxmixer. The mixing is straight addition. i.e. When signals are mixed, 100% of all the signals involved, are added to each other, unless a slider is used, in which case it is multiplied by the slider value, and then then added to the other signal(s).

My hope is that this info, together with the info in the 3D Audio forum about Surrounder, will help clear up some of the confusion regarding the default DSP setup used with kX. Additionally, it could prove useful in finding other ways that you could use the xrouting plugin within a custom DSP setup, etc.

I know that there has been some confusion over the directional indicators used in some of the names of the inputs and outputs. They are used to represent 8 point surround sound where:

nw = front left
n = center
ne = front right
w = left
e = right
sw = rear left
s = rear center
se = rear right

Some of the other names used are more obvious as to what they represent, while some are more generic (the generic inputs at the bottom for example), but the info below should help in determining what they are used for (under the default DSP), and which kxmixer sliders are used with which inputs, etc.

Any and all infor reguarding any plugin is much appreciated.

Thanks Russ.

BTW: I thought I should mention that the above info is for xrouting version 3.4, so as to not cause confusion if future/previous versions of xrouting are different.

I will add this to our online help and the driver help file
thanks!
