LGPL-2.1-or-later
* Mon Mar 03 2025 Martin Hauke <mardnh@gmx.de>
- Update to version 1.24.2
* Implemented the AL_SOFT_bformat_hoa extension.
* Implemented default device change events for the PulseAudio
backend.
* Implemented an option for WASAPI exclusive mode playback.
* Fixed reverb being too quiet for sounds from different
directions.
* Fixed building alffplay on systems without pkg-config.
* Improved output format detection for CoreAudio.
* Changed the default resampler back to Cubic Spline.
* Added an SDL3 playback backend. Disabled by default to avoid
a runtime dependency and for compatibility; a single process
can't safely use SDL2 and SDL3 together on some OSs, so enable
with care.
* Converted examples from SDL2 to SDL3.
* Integrated fmtlib into the main library and router for logging
and string formatting.
- Update to version 1.24.1
* Fixed compilation on PowerPC.
* Fixed compilation on some targets that lack lock-free 64-bit
atomics.
* Fixed a crash when parsing certain option values.
* Improved compatibility when compiling as C++20 or later.
* Integrated fmtlib for some examples and utilities.
- Update to version 1.24.0
* 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 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.
* 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.
* 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.

are near each other.

* Fixed ARM NEON detection on Windows.
* Fixed CoreAudio capture when the requested sample rate doesn't match the
system configuration.

* Sat Jan 16 2021 Matthias Mailänder <mailaender@opensuse.org>
- new version 1.21.0
* Updated library codebase to C++14.
* Implemented the AL_SOFT_effect_target extension.
* Implemented the AL_SOFT_events extension.
* Implemented the ALC_SOFT_loopback_bformat extension.
* Improved memory use for mixing voices.
* Improved detection of NEON capabilities.
* Improved handling of PulseAudio devices that lack manual start control.
* Improved mixing performance with PulseAudio.
* Improved high-frequency scaling quality for the HRTF B-Format decoder.
* Improved makemhr's HRIR delay calculation.
* Improved WASAPI capture of mono formats with multichannel input.
* Reimplemented the modulation stage for reverb.
* Enabled real-time mixing priority by default, for backends that use the setting. It can still be disabled in the config file.
* Enabled dual-band processing for the built-in quad and 7.1 output decoders.
* Fixed a potential crash when deleting an effect slot immediately after the last source using it stops.
* Fixed building with the static runtime on MSVC.
* Fixed using source stereo angles outside of -pi...+pi.
* Fixed the buffer processed event count for sources that start with empty buffers.
* Fixed trying to open an unopenable WASAPI device causing all devices to stop working.
* Fixed stale devices when re-enumerating WASAPI devices.
* Fixed using unicode paths with the log file on Windows.
* Fixed DirectSound capture reporting bad sample counts or erroring when reading samples.
* Added an in-progress extension for a callback-driven buffer type.
* Added an in-progress extension for higher-order B-Format buffers.
* Added an in-progress extension for convolution reverb.
* Added an experimental Oboe backend for Android playback. This requires the Oboe sources at build time, so that it's built as a static library included in libopenal.
* Added an option for auto-connecting JACK ports.
* Added greater-than-stereo support to the SoundIO backend.
* Modified the mixer to be fully asynchronous with the external API, and should now be real-time safe. Although alcRenderSamplesSOFT is not due to locking to check the device handle validity.
* Modified the UHJ encoder to use an all-pass FIR filter that's less harmful to non-filtered signal phase.
* Converted examples from SDL_sound to libsndfile. To avoid issues when combining SDL2 and SDL_sound.
* Worked around a 32-bit GCC/MinGW bug with TLS destructors. See: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83562
* Reduced the maximum number of source sends from 16 to 6.
* Removed the QSA backend. It's been broken for who knows how long.
* Got rid of the compile-time native-tools targets, using cmake and global initialization instead. This should make cross-compiling less troublesome.

- Add SDL2 and PortAudio backends
* Tue Feb 04 2020 Ludwig Nussel <lnussel@suse.de>

* Improved clarity a bit for the HRTF second-order ambisonic decoder.
* Improved detection of compatible layouts for SOFA files in makemhr and sofa-info.
* Added the ability to resample HRTFs on load.
* MHR files no longer need to match the device sample rate to be usable.
* Added an option to limit the HRTF's filter length.
