From f556c80d0230056335632b60c71f1567e177239e Mon Sep 17 00:00:00 2001 From: Mary Date: Fri, 26 Feb 2021 01:11:56 +0100 Subject: Haydn: Part 1 (#2007) * Haydn: Part 1 Based on my reverse of audio 11.0.0. As always, core implementation under LGPLv3 for the same reasons as for Amadeus. This place the bases of a more flexible audio system while making audout & audin accurate. This have the following improvements: - Complete reimplementation of audout and audin. - Audin currently only have a dummy backend. - Dramatically reduce CPU usage by up to 50% in common cases (SoundIO and OpenAL). - Audio Renderer now can output to 5.1 devices when supported. - Audio Renderer init its backend on demand instead of keeping two up all the time. - All backends implementation are now in their own project. - Ryujinx.Audio.Renderer was renamed Ryujinx.Audio and was refactored because of this. As a note, games having issues with OpenAL haven't improved and will not because of OpenAL design (stopping when buffers finish playing causing possible audio "pops" when buffers are very small). * Update for latest hexkyz's edits on Switchbrew * audren: Rollback channel configuration changes * Address gdkchan's comments * Fix typo in OpenAL backend driver * Address last comments * Fix a nit * Address gdkchan's comments --- .../Renderer/Server/MemoryPool/MemoryPoolState.cs | 148 +++++++++++++++++++++ 1 file changed, 148 insertions(+) create mode 100644 Ryujinx.Audio/Renderer/Server/MemoryPool/MemoryPoolState.cs (limited to 'Ryujinx.Audio/Renderer/Server/MemoryPool/MemoryPoolState.cs') diff --git a/Ryujinx.Audio/Renderer/Server/MemoryPool/MemoryPoolState.cs b/Ryujinx.Audio/Renderer/Server/MemoryPool/MemoryPoolState.cs new file mode 100644 index 00000000..ebde1403 --- /dev/null +++ b/Ryujinx.Audio/Renderer/Server/MemoryPool/MemoryPoolState.cs @@ -0,0 +1,148 @@ +// +// Copyright (c) 2019-2021 Ryujinx +// +// This program is free software: you can redistribute it and/or modify +// it under the terms of the GNU Lesser General Public License as published by +// the Free Software Foundation, either version 3 of the License, or +// (at your option) any later version. +// +// This program is distributed in the hope that it will be useful, +// but WITHOUT ANY WARRANTY; without even the implied warranty of +// MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
