7 Implemented the ALC_SOFT_HRTF extension.
9 Implemented SSE2 and SSE4.1 cubic resamplers.
11 Implemented B-Format output support for the wave file writer. This creates
12 FuMa-style first-order Ambisonics wave files (AMB format).
14 Implemented capture support for the MMDevAPI backend.
16 Implemented a stereo-mode config option for treating stereo modes as either
17 speakers or headphones.
19 Implemented per-device configuration options.
21 Fixed handling of PulseAudio and MMDevAPI devices that have identical
24 Fixed a potential lockup when stopping playback of suspended PulseAudio devices.
26 Fixed logging of Unicode characters on Windows.
28 Fixed 5.1 surround sound channels. By default it will now use the side
29 channels for the surround output. A configuration using rear channels is
32 Fixed the QSA backend potentially altering the capture format.
34 Fixed detecting MMDevAPI's default device.
36 Fixed returning the default capture device name.
38 Altered the behavior of alcSuspendContext and alcProcessContext to better
39 match certain Windows drivers.
41 Altered the panning algorithm for better side and back positioning cues
42 with surround sound output.
44 Improved support for certain older Windows apps.
46 Improved the alffplay example to support surround sound streams.
48 Improved support for building as a sub-project.
50 Added a toolchain to help with cross-compiling to Android.
54 Implemented EFX Chorus, Flanger, Distortion, Equalizer, and Compressor
57 Implemented high-pass and band-pass EFX filters.
59 Implemented the high-pass filter for the EAXReverb effect.
61 Implemented SSE2 and SSE4.1 linear resamplers.
63 Implemented Neon-enhanced non-HRTF mixers.
65 Implemented a QSA backend, for QNX.
67 Implemented the ALC_SOFT_pause_device, AL_SOFT_deferred_updates,
68 AL_SOFT_block_alignment, AL_SOFT_MSADPCM, and AL_SOFT_source_length
71 Fixed resetting mmdevapi backend devices.
73 Fixed clamping when converting 32-bit float samples to integer.
75 Fixed modulation range in the Modulator effect.
77 Several fixes for the OpenSL playback backend.
79 Fixed device specifier names that have Unicode characters on Windows.
81 Added support for filenames and paths with Unicode (UTF-8) characters on
84 Added support for alsoft.conf config files found in XDG Base Directory
85 Specification locations (XDG_CONFIG_DIRS and XDG_CONFIG_HOME, or their
86 defaults) on non-Windows systems.
88 Added a GUI configuration utility (requires Qt 4.8).
90 Added support for environment variable expansion in config options (not
91 keys or section names).
93 Added an example that uses SDL2 and ffmpeg.
95 Modified examples to use SDL_sound.
97 Modified CMake config option names for better sorting.
99 HRTF data sets specified in the hrtf_tables config option may now be
100 relative or absolute filenames.
102 Made the default HRTF data set an external file, and added a data set for
103 48khz playback in addition to 44.1khz.
105 Added support for C11 atomic methods.
107 Improved support for some non-GNU build systems.
111 Fixed a regression with retrieving the source's AL_GAIN property.
115 Fixed device enumeration with the OSS backend.
117 Reorganized internal mixing logic, so unneeded steps can potentially be
118 skipped for better performance.
120 Removed the lookup table for calculating the mixing pans. The panning is
121 now calculated directly for better precision.
123 Improved the panning of stereo source channels when using stereo output.
125 Improved source filter quality on send paths.
127 Added a config option to allow PulseAudio to move streams between devices.
129 The PulseAudio backend will now attempt to spawn a server by default.
131 Added a workaround for a DirectSound bug relating to float32 output.
133 Added SSE-based mixers, for HRTF and non-HRTF mixing.
135 Added support for the new AL_SOFT_source_latency extension.
137 Improved ALSA capture by avoiding an extra buffer when using sizes
138 supported by the underlying device.
140 Improved the makehrtf utility to support new options and input formats.
142 Modified the CFLAGS declared in the pkg-config file so the "AL/" portion of
143 the header includes can optionally be omitted.
145 Added a couple example code programs to show how to apply reverb, and
148 The configuration sample is now installed into the share/openal/ directory
149 instead of /etc/openal.
151 The configuration sample now gets installed by default.
