Implementation of the EBU R128 loudness standard.
The European Broadcasting Union Loudness Recommendation (EBU R128) informs broadcasters how they can analyze and normalize audio so that each piece of audio sounds roughly the same volume to the human ear.
This crate provides an API which analyzes audio and outputs perceived loudness. The results can then be used to normalize volume during playback.
Features:
This crate is a Rust port of the libebur128 C library, produces the same results as the C library and has comparable performance.
EBU TECH 3341/3342 ComplianceCurrently, the implementation passes all tests defined in EBU - TECH 3341 and EBU - TECH 3342.
ebur128 optionally provides a C API that is API/ABI-compatible with libebur128. It can be built and installed via cargo-c:
# If cargo-c was not installed yet $ cargo install cargo-c # Change the prefix to the place where it should be installed $ cargo cbuild --prefix /usr/local $ cargo cinstall --prefix /usr/local
This installs a shared library, static library, C header and pkg-config file that is compatible with libebur128.
