Kuules is 35 plugins for immersive audio: mixing, sound design and delivery, in ambisonics, up to 10th order. Five of them are free.
Pick the work you do; each bundle says why every plugin in it is there.
Most ambisonic tools get sound in and out. Kuules works on the field once it exists: its room, its tone, its distance, its detail.
The body of the field and its sharp detail can be treated separately, in the same three colours in every plugin.
Wherever a control's effect can be drawn, it is drawn — which is how you learn a field by working in it.
