Rotator
This tool rotates the $L^\text{th}$ degree Ambisonic scene around the $z$-axis (yaw angle), $y$-axis (pitch angle) and $x$-axis (roll angle),
according to Fig.1. Driven with OSC from head-tracking signals, this tool can compensate the head rotations during binaural playback. Implementation according to 1 with corrections.
Compilation parameters
L: maximal Spherical Harmonics degree (i.e., Ambisonics order, $L > 0$)
Inputs / Outputs
- Inputs: $(L+1)^2$
- Outputs: $(L+1)^2$
