Automated Loudness and Metadata Correction

The DP600 builds on the technology developed for the award-winning Dolby LM100

Broadcast Loudness Meter with Dialogue Intelligence™ and closes the loop in the

measurement and correction process. It gives users the ability to automatically

normalize the loudness of all their le-based content in faster than real time while

preserving their original dynamic range.

This unique process guarantees that important metadata parameters such as dialogue

normalization are set properly for every le (program) without user intervention

and without the time-consuming measurement and correction processes that were

previously done in real time.

In very rare cases involving extreme loudness corrections that require gain, soft limiting will occur only

during program peak levels that would exceed clipping after applying this type of loudness correction.
