openal-soft-1.18.2:
Fixed resetting the FPU rounding mode after certain function calls on
Windows.
Fixed use of SSE intrinsics when building with Clang on Windows.
Fixed a crash with the JACK backend when using JACK1.
Fixed use of pthread_setnane_np on NetBSD.
Fixed building on FreeBSD with an older freebsd-lib.
OSS now links with libossaudio if found at build time (for NetBSD).
openal-soft-1.18.1:
Fixed an issue where resuming a source might not restart playing it.
Fixed PulseAudio playback when the configured stream length is much less
than the requested length.
Fixed MMDevAPI capture with sample rates not matching the backing device.
Fixed int32 output for the Wave Writer.
Fixed enumeration of OSS devices that are missing device files.
Added correct retrieval of the executable's path on FreeBSD.
Added a config option to specify the dithering depth.
Added a 5.1 decoder preset that excludes front-center output.
openal-soft-1.18.0:
Implemented the AL_EXT_STEREO_ANGLES and AL_EXT_SOURCE_RADIUS extensions.
Implemented the AL_SOFT_gain_clamp_ex, AL_SOFT_source_resampler,
AL_SOFT_source_spatialize, and ALC_SOFT_output_limiter extensions.
Implemented 3D processing for some effects. Currently implemented for
Reverb, Compressor, Equalizer, and Ring Modulator.
Implemented 2-channel UHJ output encoding. This needs to be enabled with a
config option to be used.
Implemented dual-band processing for high-quality ambisonic decoding.
Implemented distance-compensation for surround sound output.
Implemented near-field emulation and compensation with ambisonic rendering.
Currently only applies when using the high-quality ambisonic decoder or
ambisonic output, with appropriate config options.
Implemented an output limiter to reduce the amount of distortion from
clipping.
Implemented dithering for 8-bit and 16-bit output.
Implemented a config option to select a preferred HRTF.
Implemented a run-time check for NEON extensions using /proc/cpuinfo.
Implemented experimental capture support for the OpenSL backend.
Fixed building on compilers with NEON support but don't default to having
NEON enabled.
Fixed support for JACK on Windows.
Fixed starting a source while alcSuspendContext is in effect.
Fixed detection of headsets as headphones, with MMDevAPI.
Added support for AmbDec config files, for custom ambisonic decoder
configurations. Version 3 files only.
Added backend-specific options to alsoft-config.
Added first-, second-, and third-order ambisonic output formats. Currently
only works with backends that don't rely on channel labels, like JACK,
ALSA, and OSS.
Added a build option to embed the default HRTFs into the lib.
Added AmbDec presets to enable high-quality ambisonic decoding.
Added an AmbDec preset for 3D7.1 speaker setups.
Added documentation regarding Ambisonics, 3D7.1, AmbDec config files, and
the provided ambdec presets.
Added the ability for MMDevAPI to open devices given a Device ID or GUID
string.
Added an option to the example apps to open a specific device.
Increased the maximum auxiliary send limit to 16 (up from 4). Requires
requesting them with the ALC_MAX_AUXILIARY_SENDS context creation
attribute.
Increased the default auxiliary effect slot count to 64 (up from 4).
Reduced the default period count to 3 (down from 4).
Slightly improved automatic naming for enumerated HRTFs.
Improved B-Format decoding with HRTF output.
Improved internal property handling for better batching behavior.
Improved performance of certain filter uses.
Removed support for the AL_SOFT_buffer_samples and AL_SOFT_buffer_sub_data
extensions. Due to conflicts with AL_EXT_SOURCE_RADIUS.
