- For multichannel or ambisonics, the user can specify:
- a triplet of
gain, azimuth, elevationto pan the signal to the desired position - a panning matrix of dimension [ num_lfe_in x num_ch_out ] with elements specifying output gain
- a triplet of
- For Binaural rendering, the recommendation by Dolby will be applied, where LFE is added to both left and right ears with 5.5dB gain after LPF.
- For multichannel or ambisonics, the user can specify:
