The presets are prepared to work with OpenAL Soft's high +quality decoder. By default all of the speaker distances within a preset are +set to the same value, which results in no effect from distance compensation. +If this doesn't match your physical speaker setup, it may be worth copying the +preset and modifying the distance values to match (note that modifying the +azimuth and elevation values in the presets will not have any effect; the +specified angles do not change the decoder behavior). + +Details of the individual presets are as follows. + +square.ambdec +Specifies a basic square speaker setup for Quadrophonic output, with identical +width and depth. Front speakers are placed at +45 and -45 degrees, and back +speakers are placed at +135 and -135 degrees. + +rectangle.ambdec +Specifies a narrower speaker setup for Quadrophonic output, with a little less +width but a little more depth over a basic square setup. Front speakers are +placed at +30 and -30 degrees, providing a bit more compatibility for existing +stereo content, with back speakers at +150 and -150 degrees. + +hexagon.ambdec +Specifies a flat-front hexagonal speaker setup for 7.1 Surround output. The +front left and right speakers are placed at +30 and -30 degrees, the side +speakers are placed at +90 and -90 degrees, and the back speakers are placed at ++150 and -150 degrees. Although this is for 7.1 output, no front-center speaker +is defined for the decoder, meaning that speaker will be silent for 3D sound +(however it may still be used with AL_SOFT_direct_channels or ALC_EXT_DEDICATED +output). A "proper" 7.1 decoder may be provided in the future, but due to the +nature of the speaker configuration will have trade-offs. + +3D7.1.ambdec +Specifies a 3D7.1 speaker setup for 7.1 Surround output. Although it's for 7.1 +output, the speakers for such a configuration need to be placed in different +positions for proper results. Please see docs/3D7.1.txt for more information. diff --git a/presets/rectangle.ambdec b/presets/rectangle.ambdec new file mode 100644 index 00000000..caf72318 --- /dev/null +++ b/presets/rectangle.ambdec @@ -0,0 +1,45 @@ +# AmbDec configuration +# Written by Ambisonic Decoder Toolbox, version 8.0 + +/description Rectangle_1h0p_pinv_match_rV_max_rE_2_band + +/version 3 + +/dec/chan_mask b +/dec/freq_bands 2 +/dec/speakers 4 +/dec/coeff_scale fuma + +/opt/input_scale fuma +/opt/nfeff_comp input +/opt/delay_comp on +/opt/level_comp on +/opt/xover_freq 400.000000 +/opt/xover_ratio 0.000000 + +/speakers/{ +# id dist azim elev conn +#----------------------------------------------------------------------- +add_spkr LF 1.000000 30.000000 0.000000 +add_spkr RF 1.000000 -30.000000 0.000000 +add_spkr RB 1.000000 -150.000000 0.000000 +add_spkr LB 1.000000 150.000000 0.000000 +/} + +/lfmatrix/{ +order_gain 1.000000 1.000000 0.000000 0.000000 +add_row 0.353553 0.500000 0.288675 +add_row 0.353553 -0.500000 0.288675 +add_row 0.353553 -0.500000 -0.288675 +add_row 0.353553 0.500000 -0.288675 +/} + +/hfmatrix/{ +order_gain 1.414214 1.000000 0.000000 0.000000 +add_row 0.353553 0.500000 0.288675 +add_row 0.353553 -0.500000 0.288675 +add_row 0.353553 -0.500000 -0.288675 +add_row 0.353553 0.500000 -0.288675 +/} + +/end diff --git a/presets/square.ambdec b/presets/square.ambdec new file mode 100644 index 00000000..547ed367 --- /dev/null +++ b/presets/square.ambdec @@ -0,0 +1,45 @@ +# AmbDec configuration +# Written by Ambisonic Decoder Toolbox, version 8.0 + +/description Square_1h0p_pinv_match_rV_max_rE_2_band + +/version 3 + +/dec/chan_mask b +/dec/freq_bands 2 +/dec/speakers 4 +/dec/coeff_scale fuma + +/opt/input_scale fuma +/opt/nfeff_comp input +/opt/delay_comp on +/opt/level_comp on +/opt/xover_freq 400.000000 +/opt/xover_ratio 0.000000 + +/speakers/{ +# id dist azim elev conn +#----------------------------------------------------------------------- +add_spkr LF 1.000000 45.000000 0.000000 +add_spkr RF 1.000000 -45.000000 0.000000 +add_spkr RB 1.000000 -135.000000 0.000000 +add_spkr LB 1.000000 135.000000 0.000000 +/} + +/lfmatrix/{ +order_gain 1.000000 1.000000 0.000000 0.000000 +add_row 0.353553 0.353553 0.353553 +add_row 0.353553 -0.353553 0.353553 +add_row 0.353553 -0.353553 -0.353553 +add_row 0.353553 0.353553 -0.353553 +/} + +/hfmatrix/{ +order_gain 1.414214 1.000000 0.000000 0.000000 +add_row 0.353553 0.353553 0.353553 +add_row 0.353553 -0.353553 0.353553 +add_row 0.353553 -0.353553 -0.353553 +add_row 0.353553 0.353553 -0.353553 +/} + +/end |
