Azimuth Rotator

This tool rotates the $L^\text{th}$ degree Ambisonic scene around the $z$-axis (azimuth angle). Driven with OSC from head-tracking signals, this tool can compensate the head rotations during binaural playback. Implementation according to ¹ with corrections.

Compilation parameter

• L: maximal Spherical Harmonics degree (i.e., Ambisonics order, $L \geq 0$)

Inputs / Outputs

• Inputs: $(L+1)^2$
• Outputs: $(L+1)^2$
