From 8b00954ec79fad71691ad2d4c82d5c1c60e21b0c Mon Sep 17 00:00:00 2001 From: MerryMage Date: Sun, 21 Feb 2016 13:13:52 +0000 Subject: AudioCore: Skeleton Implementation This commit: * Adds a new subproject, audio_core. * Defines structures that exist in DSP shared memory. * Hooks up various other parts of the emulator into audio core. This sets the foundation for a later HLE DSP implementation. --- src/audio_core/sink.h | 34 ++++++++++++++++++++++++++++++++++ 1 file changed, 34 insertions(+) create mode 100644 src/audio_core/sink.h (limited to 'src/audio_core/sink.h') diff --git a/src/audio_core/sink.h b/src/audio_core/sink.h new file mode 100644 index 000000000..cad21a85e --- /dev/null +++ b/src/audio_core/sink.h @@ -0,0 +1,34 @@ +// Copyright 2016 Citra Emulator Project +// Licensed under GPLv2 or any later version +// Refer to the license.txt file included. + +#pragma once + +#include + +#include "common/common_types.h" + +namespace AudioCore { + +/** + * This class is an interface for an audio sink.
