/description 3D7-noCenter_1h1v_pinv_even_energy_rV_max_rE_2_band
# In OpenAL Soft, 3D7.1 is a distinct configuration that uses the standard 5.1
# channels (LF, RF, CE, LS, RS), plus two auxiliary channels (AUX0, AUX1) in
# place of the rear speakers. AUX0 corresponds to the LB speaker (upper back
# center), and AUX1 corresponds to the RB speaker (lower front center).
# Similar to the the ITU-5.1-nocenter configuration, the front-center is
# declared here so that an appropriate distance may be set (for proper delaying
# or attenuating of dialog and such which feed it directly). It otherwise does
# not contribute to positional sound output due to its irregular position.
