We created a plugin for Harmonic's Rhozet Carbon Coder that automatically measures the loudness and true peak values of the materials and normalize them according to a specified target.
The measurements can be done for up to 32 channels. C-Normalizer is fully compliant with loudness measurement standards : ITU-R BS.1770-3 (with the relative gate of -10 LU) and EBU R-128. The normalization is done according to the desired value of Program Loudness or Max Short Term Loudness. In most cases, in order to maintain the original program dynamics, the normalization consist in a simply linear gain modification. Besides, C-Normalizer is capable of creating two log files of the program material, for evaluation and quality control of the descriptors (Program Loudness, Max. Short Term Loudness, Max. Momentary Loudness, Loudness Range and Max. True Peak) with their time code position for both source and target. It also contains a True Peak Limiter, which assures you that when you make the normalization of the audio program, the value of Max True Peak doesn't exceed the desired value.
