compress the field, keep the image

A compressor on an ambisonic bus that treats channels separately pulls the image apart. Kuules Compress works on the field in lanes — the omni, the first order, the higher orders — and keeps the source where it was.

Fenced, not hoped. Every build is tested: a source in front stays in front; the rear null stays a null.
Threshold, ratio and knee for the body of the field and for its detail, separately.
Or by direction: level the loud directions, lift the quiet ones.
Thresholds are lines on the level graph. Drag them.
