All source code is licensed under the MIT license. See LICENSE file for details.
The loudness scanning tool has moved to its own repository at https://github.com/jiixyj/loudness-scanner
- Portable ANSI C code
- Implements M, S and I modes
- Implements loudness range measurement (EBU - TECH 3342)
- True peak scanning
- Supports all samplerates by recalculation of the filter coefficients
The library itself has no requirements besides ANSI C.
In the root folder, type:
mkdir build cd build cmake .. make
If you want the git version, run simply:
git clone git://github.com/jiixyj/libebur128.git
Library usage should be pretty straightforward. All exported symbols are documented in the ebur128.h header file. For a usage example, see minimal-example.c in the tests folder.
On some operating systems, static libraries should be compiled as position independent code. You can enable that by turning on WITH_STATIC_PIC.
