Arguments:

in

The B-format signal, an array: [w, x, y, z]

size

Analysis filter kernel size.

NOTE: For method: 'instant', must be a power of 2.
method

The Soundfield analysis method:

  • 'instant'
  • 'average'
WARNING: This UGen requires the reactive intensity vector, so will throw an error if called with the 'average' keyword.

Please see discussion of method here.
