Changed

  • Audio and IO modules can now be disabled during KFR build with KFR_ENABLE_AUDIO and KFR_ENABLE_IO options (both on by default) @jcelerier
  • DSP module can be disabled too with KFR_ENABLE_DSP option (on by default)
  • Documentation migrated to mkdocs + cxxdox 2
  • Prebuilt binaries are tested after build
  • Prebuilt binaries use Clang 21
  • KFR_ENABLE_MULTIARCH is forcibly turned off for non-x86
  • KFR_USE_BOOST_MATH option enables the use of standalone Boost.Math for elliptic filters (on by default)
  • KFR_USE_BOOST option switches to using Boost.Math from a full Boost installation. Enable if you already use Boost
  • C++20 standard is now handled via the cxx_std_20 CMake feature and inherited by dependent targets
  • Refactored CMake config with separate targets and dependency handling
  • add_kfr_library refactored to distinguish between private and public dependencies and definitions
  • In multiarch builds, the base architecture is now named exactly as the module itself (was: kfr_dsp_sse2, kfr_dsp_avx2; now: kfr_dsp, kfr_dsp_avx2)
  • Examples and tools migrated to the new audio I/O code
  • All third-party libraries moved to src/thirdparty or include/kfr/thirdparty
  • Old audio I/O handled by audio_reader and audio_writer is now deprecated
  • reverse expression is now writable
  • audio_sample_type now represents bit depth; negative if floating-point
  • convert_endianness now accepts references to data types

    • iir_params<float_type> still accepts a template parameter to control precision
    • to_sos now accepts float_type (default double) to return iir_params<float_type>
    • New elliptic function follows the same rule and always produces double-precision zpk
