From 9a4beac95a0f88ec312a28d06da8270aa58736e3 Mon Sep 17 00:00:00 2001 From: Chloe Marcec Date: Tue, 17 Nov 2020 14:14:29 +1100 Subject: audren: Make use of nodiscard, rework downmixing, release all buffers Preliminary work for upmixing & general cleanup. Fixes basic issues in games such as Shovel Knight and slightly improves the LEGO games. Upmixing stitll needs to be implemented. Audio levels in a few games will be fixed as we now use the downmix coefficients when possible instead of supplying our own --- src/audio_core/audio_out.cpp | 4 ++ src/audio_core/audio_out.h | 3 + src/audio_core/audio_renderer.cpp | 110 ++++++++++++++++++++++++++++--------- src/audio_core/audio_renderer.h | 20 +++---- src/audio_core/behavior_info.h | 30 +++++----- src/audio_core/command_generator.h | 14 ++--- src/audio_core/common.h | 2 +- src/audio_core/effect_context.h | 26 ++++----- src/audio_core/mix_context.h | 26 ++++----- src/audio_core/sink_context.cpp | 18 +++++- src/audio_core/sink_context.h | 13 +++-- src/audio_core/stream.cpp | 9 +++ src/audio_core/stream.h | 21 ++++--- 13 files changed, 194 insertions(+), 102 deletions(-) (limited to 'src') diff --git a/src/audio_core/audio_out.cpp b/src/audio_core/audio_out.cpp index 8619a3f03..fe3a898ad 100644 --- a/src/audio_core/audio_out.cpp +++ b/src/audio_core/audio_out.cpp @@ -43,6 +43,10 @@ std::vector AudioOut::GetTagsAndReleaseBuffers(StreamPtr stream, return stream->GetTagsAndReleaseBuffers(max_count);
