OpenAL Soft v1.24.0

A long overdue release. This release's highlights include:

• Updated library codebase to C++17.
• Implemented the ALC_SOFT_system_events extension.
• Implemented the AL_EXT_debug extension.
• Implemented the AL_EXT_direct_context extension.
• Implemented speaker configuration and headphones detection on CoreAudio.
• Fixed a potential crash with some extension functions on 32-bit Windows.
• Fixed a crash that can occur when stopping playback with the Oboe backend.
• Fixed calculating the reverb room rolloff.
• Fixed EAX occlusion, obstruction, and exclusion low-pass filter strength.
• Fixed EAX distance factor calculations.
• Fixed querying AL_EFFECTSLOT_EFFECT on auxiliary effect slots.
• Fixed compilation on some macOS systems that lack libdispatch.
• Fixed compilation as a subproject with MinGW.
• Changed the context error state to be thread-local. This is technically out of spec, but necessary to avoid race conditions with multi-threaded use.
• Split the cubic resampler into 4-point spline and gaussian variants. The latter prioritizing the suppression of aliasing distortion and harmonics, the former not reducing high frequencies as much.
• Improved timing precision of starting delayed sources.
• Improved ring modulator quality.
• Improved performance of convolution reverb.
• Improved WASAPI device enumeration performance.
• Added UWP support.
• Added 'noexcept' to functions and function types when compiled as C++. As a C API, OpenAL can't be expected to throw C++ exceptions, nor can it handle them if they leave a callback.
• Added an experimental config option for using WASAPI spatial audio output.
• Added enumeration support to the PortAudio backend.
• Added compatibility options to override the AL_VENDOR, AL_VERSION, and AL_RENDERER strings.
• Added an example to play LAF files.
• Disabled real-time mixing by default for PipeWire playback.
• Disabled the SndIO backend by default on non-BSD targets.
