From d38c8419c7374286db35e9e8b63abfd1cefac302 Mon Sep 17 00:00:00 2001 From: Chris Robinson Date: Wed, 30 Jun 2021 15:53:15 -0700 Subject: Update the 5.1+center decoder and use it by default The itu5.1-nocenter preset is the same as the previous default, so it can still be used for people that prefer it. But this new one purportedly has better panning and positioning responses in listening tests, which initial impressions concur with. --- alc/panning.cpp | 63 +++++++++++++++++++++++++++++++++++---------------------- 1 file changed, 39 insertions(+), 24 deletions(-) (limited to 'alc') diff --git a/alc/panning.cpp b/alc/panning.cpp index 0ed401a1..2c99d978 100644 --- a/alc/panning.cpp +++ b/alc/panning.cpp @@ -289,13 +289,6 @@ void InitDistanceComp(ALCdevice *device, DecoderView decoder, } -inline auto& GetAmbiScales(AmbDecScale scaletype) noexcept -{ - if(scaletype == AmbDecScale::FuMa) return AmbiScale::FromFuMa(); - if(scaletype == AmbDecScale::SN3D) return AmbiScale::FromSN3D(); - return AmbiScale::FromN3D(); -} - inline auto& GetAmbiScales(DevAmbiScaling scaletype) noexcept { if(scaletype == DevAmbiScaling::FuMa) return AmbiScale::FromFuMa(); @@ -489,26 +482,44 @@ constexpr DecoderConfig QuadConfig{ {{2.50000000e-1f, -2.04124145e-1f, -2.04124145e-1f, 1.29099445e-1f, 0.00000000e+0f}}, }} }; -constexpr DecoderConfig X51Config{ - 2, false, {{SideLeft, FrontLeft, FrontRight, SideRight}}, - DevAmbiScaling::N3D, - {{1.0f, 1.0f, 1.0f}}, +constexpr DecoderConfig X51Config{ + 2, false, {{SideLeft, FrontLeft, FrontCenter, FrontRight, SideRight}}, + DevAmbiScaling::FuMa, + /*HF*/{{1.00000000e+0f, 1.00000000e+0f, 1.00000000e+0f}}, + {{ + {{5.67316000e-1f, 4.22920000e-1f, -3.15495000e-1f, -6.34490000e-2f, -2.92380000e-2f}}, + {{3.68584000e-1f, 2.72349000e-1f, 3.21616000e-1f, 1.92645000e-1f, 4.82600000e-2f}}, + {{1.83579000e-1f, 0.00000000e+0f, 1.99588000e-1f, 0.00000000e+0f, 9.62820000e-2f}}, + {{3.68584000e-1f, -2.72349000e-1f, 3.21616000e-1f, -1.92645000e-1f, 4.82600000e-2f}}, + {{5.67316000e-1f, -4.22920000e-1f, -3.15495000e-1f, 6.34490000e-2f, -2.92380000e-2f}}, + }}, + /*LF*/{{1.00000000e+0f, 1.00000000e+0f, 1.00000000e+0f}}, {{ - {{3.33000782e-1f, 1.89084803e-1f, -2.00042375e-1f, -2.12307769e-2f, -1.14579885e-2f}}, - {{1.88542860e-1f, 1.27709292e-1f, 1.66295695e-1f, 7.30571517e-2f, 2.10901184e-2f}}, - {{1.88542860e-1f, -1.27709292e-1f, 1.66295695e-1f, -7.30571517e-2f, 2.10901184e-2f}}, - {{3.33000782e-1f, -1.89084803e-1f, -2.00042375e-1f, 2.12307769e-2f, -1.14579885e-2f}}, + {{4.90109850e-1f, 3.77305010e-1f, -3.73106990e-1f, -1.25914530e-1f, 1.45133000e-2f}}, + {{1.49085730e-1f, 3.03561680e-1f, 1.53290060e-1f, 2.45112480e-1f, -1.50753130e-1f}}, + {{1.37654920e-1f, 0.00000000e+0f, 4.49417940e-1f, 0.00000000e+0f, 2.57844070e-1f}}, + {{1.49085730e-1f, -3.03561680e-1f, 1.53290060e-1f, -2.45112480e-1f, -1.50753130e-1f}}, + {{4.90109850e-1f, -3.77305010e-1f, -3.73106990e-1f, 1.25914530e-1f, 1.45133000e-2f}}, }} }; -constexpr DecoderConfig X51RearConfig{ - 2, false, {{BackLeft, FrontLeft, FrontRight, BackRight}}, - DevAmbiScaling::N3D, - {{1.0f, 1.0f, 1.0f}}, +constexpr DecoderConfig X51RearConfig{ + 2, false, {{BackLeft, FrontLeft, FrontCenter, FrontRight, BackRight}}, + DevAmbiScaling::FuMa, + /*HF*/{{1.00000000e+0f, 1.00000000e+0f, 1.00000000e+0f}}, {{ - {{3.33000782e-1f, 1.89084803e-1f, -2.00042375e-1f, -2.12307769e-2f, -1.14579885e-2f}}, - {{1.88542860e-1f, 1.27709292e-1f, 1.66295695e-1f, 7.30571517e-2f, 2.10901184e-2f}}, - {{1.88542860e-1f, -1.27709292e-1f, 1.66295695e-1f, -7.30571517e-2f, 2.10901184e-2f}}, - {{3.33000782e-1f, -1.89084803e-1f, -2.00042375e-1f, 2.12307769e-2f, -1.14579885e-2f}}, + {{5.67316000e-1f, 4.22920000e-1f, -3.15495000e-1f, -6.34490000e-2f, -2.92380000e-2f}}, + {{3.68584000e-1f, 2.72349000e-1f, 3.21616000e-1f, 1.92645000e-1f, 4.82600000e-2f}}, + {{1.83579000e-1f, 0.00000000e+0f, 1.99588000e-1f, 0.00000000e+0f, 9.62820000e-2f}}, + {{3.68584000e-1f, -2.72349000e-1f, 3.21616000e-1f, -1.92645000e-1f, 4.82600000e-2f}}, + {{5.67316000e-1f, -4.22920000e-1f, -3.15495000e-1f, 6.34490000e-2f, -2.92380000e-2f}}, + }}, + /*LF*/{{1.00000000e+0f, 1.00000000e+0f, 1.00000000e+0f}}, + {{ + {{4.90109850e-1f, 3.77305010e-1f, -3.73106990e-1f, -1.25914530e-1f, 1.45133000e-2f}}, + {{1.49085730e-1f, 3.03561680e-1f, 1.53290060e-1f, 2.45112480e-1f, -1.50753130e-1f}}, + {{1.37654920e-1f, 0.00000000e+0f, 4.49417940e-1f, 0.00000000e+0f, 2.57844070e-1f}}, + {{1.49085730e-1f, -3.03561680e-1f, 1.53290060e-1f, -2.45112480e-1f, -1.50753130e-1f}}, + {{4.90109850e-1f, -3.77305010e-1f, -3.73106990e-1f, 1.25914530e-1f, 1.45133000e-2f}}, }} }; constexpr DecoderConfig X61Config{ @@ -618,8 +629,12 @@ void InitPanning(ALCdevice *device, const bool hqdec=false, const bool stablize= } } - /* For non-DevFmtAmbi3D, set the ambisonic order. */ + /* For non-DevFmtAmbi3D, set the ambisonic order and reset the layout and + * scale. + */ device->mAmbiOrder = decoder.mOrder; + device->mAmbiLayout = DevAmbiLayout::ACN; + device->mAmbiScale = DevAmbiScaling::N3D; const size_t ambicount{decoder.mIs3D ?
