openal-soft: Update to 1.20.1

openal-soft-1.20.1:

    Implemented the AL_SOFT_direct_channels_remix extension. This extends
    AL_DIRECT_CHANNELS_SOFT to optionally remix input channels that don't have
    a matching output channel.

    Implemented the AL_SOFT_bformat_ex extension. This extends B-Format buffer
    support for N3D or SN3D scaling, or ACN channel ordering.

    Fixed a potential voice leak when a source is started and stopped or
    restarted in quick succession.

    Fixed a potential device reset failure with JACK.

    Improved handling of unsupported channel configurations with WASAPI. Such
    setups will now try to output at least a stereo mix.

    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.

openal-soft: Update to 1.20.0

pkgsrc changes:

- Support more audio backends.

openal-soft-1.20.0:

    Converted the library codebase to C++11. A lot of hacks and custom
    structures have been replaced with standard or cleaner implementations.

    Partially implemented the Vocal Morpher effect.

    Fixed the bsinc SSE resamplers on non-GCC compilers.

    Fixed OpenSL capture.

    Fixed support for extended capture formats with OpenSL.

    Fixed handling of WASAPI not reporting a default device.

    Fixed performance problems relating to semaphores on macOS.

    Modified the bsinc12 resampler's transition band to better avoid aliasing
    noise.

    Modified alcResetDeviceSOFT to attempt recovery of disconnected devices.

    Modified the virtual speaker layout for HRTF B-Format decoding.

    Modified the PulseAudio backend to use a custom processing loop.

    Renamed the makehrtf utility to makemhr.

    Improved the efficiency of the bsinc resamplers when up-sampling.

    Improved the quality of the bsinc resamplers slightly.

    Improved the efficiency of the HRTF filters.

    Improved the HRTF B-Format decoder coefficient generation.

    Improved reverb feedback fading to be more consistent with pan fading.

    Improved handling of sources that end prematurely, avoiding loud clicks.

    Improved the performance of some reverb processing loops.

    Added fast_bsinc12 and 24 resamplers that improve efficiency at the cost of
    some quality. Notably, down-sampling has less smooth pitch ramping.

    Added support for SOFA input files with makemhr.

    Added a build option to use pre-built native tools. For cross-compiling,
    use with caution and ensure the native tools' binaries are kept up-to-date.

    Added an adjust-latency config option for the PulseAudio backend.

    Added basic support for multi-field HRTFs.

    Added an option for mixing first- or second-order B-Format with HRTF
    output. This can improve HRTF performance given a number of sources.

    Added an RC file for proper DLL version information.

    Disabled some old KDE workarounds by default. Specifically, PulseAudio
    streams can now be moved (KDE may try to move them after opening).

openal-soft: Update COMMENT and DESCR.

This isn't really an 'alternative' any more, it's the implementation
preferred by most vendors.

Log message:
openal-soft: update to 1.19.1.

openal-soft-1.19.1:

    Implemented capture support for the SoundIO backend.

    Fixed source buffer queues potentially not playing properly when a queue
    entry completes.

    Fixed possible unexpected failures when generating auxiliary effect slots.

    Fixed a crash with certain reverb or device settings.

    Fixed OpenSL capture.

    Improved output limiter response, better ensuring the sample amplitude is
    clamped for output.

openal-soft-1.19.0:

    Implemented the ALC_SOFT_device_clock extension.

    Implemented the Pitch Shifter, Frequency Shifter, and Autowah effects.

    Fixed compiling on FreeBSD systems that use freebsd-lib 9.1.

    Fixed compiling on NetBSD.

    Fixed the reverb effect's density scale and panning parameters.

    Fixed use of the WASAPI backend with certain games, which caused odd COM
    initialization errors.

    Increased the number of virtual channels for decoding Ambisonics to HRTF
    output.

    Changed 32-bit x86 builds to use SSE2 math by default for performance.
    Build-time options are available to use just SSE1 or x87 instead.

    Replaced the 4-point Sinc resampler with a more efficient cubic resampler.

    Renamed the MMDevAPI backend to WASAPI.

    Added support for 24-bit, dual-ear HRTF data sets. The built-in data set
    has been updated to 24-bit.

    Added a 24- to 48-point band-limited Sinc resampler.

    Added an SDL2 playback backend. Disabled by default to avoid a dependency
    on SDL2.

    Improved the performance and quality of the Chorus and Flanger effects.

    Improved the efficiency of the band-limited Sinc resampler.

    Improved the Sinc resampler's transition band to avoid over-attenuating
    higher frequencies.

    Improved the performance of some filter operations.

    Improved the efficiency of object ID lookups.

    Improved the efficienty of internal voice/source synchronization.

    Improved AL call error logging with contextualized messages.

    Removed the reverb effect's modulation stage. Due to the lack of reference
    for its intended behavior and strength.

Log message:
openal-soft: update to 1.18.2.

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).
