implements the EBU R 128 standard for loudness\nnormalisation.\n\nAll source code is licensed under the MIT license. See COPYING file for\ndetails.\n\nSee also [loudness-scanner tool](https://github.com/jiixyj/loudness-scanner).\n\nNews\n----\n\nv1.2.6 released:\n * Fix dynamic linking on Windows.\n\nv1.2.5 released:\n * Remove `BUILD_STATIC_LIBS` build option. Instead the CMake-supported\n   `BUILD_SHARED_LIBS` option is now honored as expected.\n * Various code cleanups, warning fixes and documentation improvements\n * Fix issue related to filter state indexing with high channel enums (#77)\n * Introduce limits for number of channels and maximum supported samplerate to\n   avoid integer overflows\n * Fix error return code of `ebur128_set_channel`. The actual behavior is now\n   aligned to the documentation (#90).\n\nv1.2.4 released:\n * Fix broken `ebur128_loudness_global_multiple()` function. Since v1.1.0 it\n   calculated the relative threshold just from the last state given to it,\n   resulting in wrong values.\n * More tests\n * Fix some minor build issues\n * Fix uninitialized memory in `ebur128_init()`, possibly resulting in wrong\n   values\n\nv1.2.3 released:\n * Fix uninitialized memory access during true peak scanning (bug #72)\n\nv1.2.2 released (v1.2.1 was mistagged):\n * Fix a null pointer dereference when doing true peak scanning of 192kHz data\n\nv1.2.0 released:\n\n * New functions for real time loudness/peak monitoring:\n   * `ebur128_loudness_window()`\n   * `ebur128_set_max_window()`\n   * `ebur128_set_max_history()`\n   * `ebur128_prev_sample_peak()`\n   * `ebur128_prev_true_peak()`\n * New FIR resampler for true peak calculation, removing Speex dependency\n * Add true peak conformance tests\n * Bug fixes\n\nv1.1.0 released:\n\n * Add `ebur128_relative_threshold()`\n * Add channel definitions from ITU R-REC-BS 1770-4 to channel enum\n * Fix some minor build issues\n\nv1.0.3 released:\n\n * Fix build with recent speexdsp\n * Correct license file name\n * CMake option to disable static library\n * minimal-example.c: do not hard code program name in usage\n\nFeatures\n--------\n\n* Portable ANSI C code\n* Implements M, S and I modes\n* Implements loudness range measurement (EBU - TECH 3342)\n* True peak scanning\n* Supports all samplerates by recalculation of the filter coefficients\n\nInstallation\n------------\n\nIn the root folder, type:\n\n    mkdir build\n    cd build\n    cmake ..\n    make\n\nIf you want the git version, run simply:\n\n    git clone git://github.com/jiixyj/libebur128.git\n\nUsage\n-----\n\nLibrary usage should be pretty straightforward. All exported symbols are\ndocumented in the ebur128.h header file. For a usage example, see\nminimal-example.c in the tests folder.\n\nOn some operating systems, static libraries should be compiled as position\nindependent code. You can enable that by turning on `WITH_STATIC_PIC`.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjiixyj%2Flibebur128","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjiixyj%2Flibebur128","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjiixyj%2Flibebur128/lists"}
