From 5f7268c0cc356b08db0d25ca3e665078180d0aec Mon Sep 17 00:00:00 2001 From: Chris Robinson Date: Tue, 18 Jul 2017 20:30:45 -0700 Subject: Add a 5.1 preset that excludes the front-center speaker On some speaker setups, the front-center speaker is not designed for full-range content and should be used exclusively for dialog. Consequently it should not be used for positional sounds, only the dedicated dialog effect. --- presets/itu5.1-nocenter.ambdec | 46 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 presets/itu5.1-nocenter.ambdec (limited to 'presets') diff --git a/presets/itu5.1-nocenter.ambdec b/presets/itu5.1-nocenter.ambdec new file mode 100644 index 00000000..23839d0e --- /dev/null +++ b/presets/itu5.1-nocenter.ambdec @@ -0,0 +1,46 @@ +# AmbDec configuration +# Written by Ambisonic Decoder Toolbox, version 8.0 + +# input channel order: WYXVU + +/description itu50-noCenter_2h0p_allrad_5200_rE_max_1_band + +# Although unused in this 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).
