EarlyRefAtkGen | SuperCollider 3.13.0 Help

Description

Generates convolution kernels for early reflections in a mono-to-ambisonic reverb. Outputs a trigger whenever the buffers change.

Arguments:

bufW
bufX
bufY
bufZ	Buffers to which the kernels will be written. All buffers should have the same size, and that size should be a power of 2 for use in PartConvT.
source	The x-, y-, and z-coordinates of the source audio in meters.
receiver	The x-, y-, and z-coordinates of the listener in meters.
roomsize	The width, height, and length of the room in meters.
hw	Ear separation in meters.
b	Reflection coefficient for the room's floor, walls, and ceiling.
n	Controls the number of mirror images to model. n = 0 generates 27 mirror images, and n = 1 to 5 generates 8(N2+1)^3 mirror images.
