Class Methods
.ar
Pseudo Ugen method returning Ugens based on Ambisonics order provided through the first argument.
Arguments:
| order |
Ambisonics order 1-5. |
| in |
b-format as channel array. |
| pitch |
pitch angle (-pi to pi). |
| roll |
roll angle (-pi to pi). |
| yaw |
yaw angle (-pi to pi). |
Returns:
b-format as channel array (4,9,16,25,36 channels depending on the order argument).
