41 Implemented a C and SSE based band-limited Sinc resampler. This does 12- to
42 24-point Sinc resampling, and performs anti-aliasing.
44 Implemented B-Format output support for the wave file writer. This creates
45 FuMa-style first-order Ambisonics wave files (AMB format).

48 speakers or headphones.
50 Implemented per-device configuration options.
52 Fixed handling of PulseAudio and MMDevAPI devices that have identical
55 Fixed a potential lockup when stopping playback of suspended PulseAudio devices.
57 Fixed logging of Unicode characters on Windows.
59 Fixed 5.1 surround sound channels. By default it will now use the side
60 channels for the surround output. A configuration using rear channels is
63 Fixed the QSA backend potentially altering the capture format.
65 Fixed detecting MMDevAPI's default device.
67 Fixed returning the default capture device name.
69 Fixed mixing property calculations when deferring context updates.
71 Altered the behavior of alcSuspendContext and alcProcessContext to better
72 match certain Windows drivers.
74 Altered the panning algorithm, utilizing Ambisonics for better side and
75 back positioning cues with surround sound output.
77 Improved support for certain older Windows apps.
79 Improved the alffplay example to support surround sound streams.
81 Improved support for building as a sub-project.
83 Added an HRTF playback example.
85 Added a tone generator output test.
87 Added a toolchain to help with cross-compiling to Android.
91 Implemented EFX Chorus, Flanger, Distortion, Equalizer, and Compressor
94 Implemented high-pass and band-pass EFX filters.
96 Implemented the high-pass filter for the EAXReverb effect.
98 Implemented SSE2 and SSE4.1 linear resamplers.
100 Implemented Neon-enhanced non-HRTF mixers.
102 Implemented a QSA backend, for QNX.
104 Implemented the ALC_SOFT_pause_device, AL_SOFT_deferred_updates,
105 AL_SOFT_block_alignment, AL_SOFT_MSADPCM, and AL_SOFT_source_length
108 Fixed resetting mmdevapi backend devices.
110 Fixed clamping when converting 32-bit float samples to integer.
112 Fixed modulation range in the Modulator effect.
114 Several fixes for the OpenSL playback backend.
116 Fixed device specifier names that have Unicode characters on Windows.
118 Added support for filenames and paths with Unicode (UTF-8) characters on
121 Added support for alsoft.conf config files found in XDG Base Directory
122 Specification locations (XDG_CONFIG_DIRS and XDG_CONFIG_HOME, or their
123 defaults) on non-Windows systems.
125 Added a GUI configuration utility (requires Qt 4.8).
127 Added support for environment variable expansion in config options (not
128 keys or section names).
130 Added an example that uses SDL2 and ffmpeg.
132 Modified examples to use SDL_sound.
134 Modified CMake config option names for better sorting.
136 HRTF data sets specified in the hrtf_tables config option may now be
137 relative or absolute filenames.
139 Made the default HRTF data set an external file, and added a data set for
140 48khz playback in addition to 44.1khz.
142 Added support for C11 atomic methods.
144 Improved support for some non-GNU build systems.
148 Fixed a regression with retrieving the source's AL_GAIN property.
152 Fixed device enumeration with the OSS backend.
154 Reorganized internal mixing logic, so unneeded steps can potentially be
155 skipped for better performance.
157 Removed the lookup table for calculating the mixing pans. The panning is
158 now calculated directly for better precision.
160 Improved the panning of stereo source channels when using stereo output.
162 Improved source filter quality on send paths.
164 Added a config option to allow PulseAudio to move streams between devices.
166 The PulseAudio backend will now attempt to spawn a server by default.
168 Added a workaround for a DirectSound bug relating to float32 output.
170 Added SSE-based mixers, for HRTF and non-HRTF mixing.
172 Added support for the new AL_SOFT_source_latency extension.
174 Improved ALSA capture by avoiding an extra buffer when using sizes
175 supported by the underlying device.
177 Improved the makehrtf utility to support new options and input formats.
179 Modified the CFLAGS declared in the pkg-config file so the "AL/" portion of
180 the header includes can optionally be omitted.
182 Added a couple example code programs to show how to apply reverb, and
185 The configuration sample is now installed into the share/openal/ directory
186 instead of /etc/openal.
188 The configuration sample now gets installed by default.
