loudnessnorm

An implementation of RMS based audio normalization in Rust. Currently, it's only able to decode WAVE files with 32-bit floating point samples (because it's easier to work with).

The loudness of the samples are normalized by calculating the RMS then the gain is changed to bring the average amplitude of the source signal to a target level (by default 0 dBFS).

Building

For Windows NT based systems just download the executable from AppVeyor. Navigate to one of the option listed there, head to ARTIFACTS tab and download the executable.

On Linux or Mac based systems, clone the repository. And, run these commands to settle things up.

cargo

• #### Why 32-bit floating point? The intent was to keep the source files the same specs. But, the WAVE library I'm using for I/O doesn't allow this kind of behaviour (conversion of sample formats is not allowed). The final descision is to keep it 32-bit floating point because sample conversion would add a overhead to the program.
