As I was getting closer to finishing my project, I looked at what requirements the were for game audio levels. For broadcast and television, the audio lever is monitored using a loudness meter as per the technical delivery standards. For games, however, there are currently no standards for audio levels. There is an on-going debate on whether to introduce technical standards for games but there is currently none.
While we think that BS.1770 would be a popular metering standard and great for short-term loudness measurement, we believe users should be able to work with whichever metering tools and standards they feel most comfortable with. Better loudness metering and normalisation at the asset level, right through submixes and up to the master mix should not only result in more predictable loudness levels but also save time when it comes to adding or modifying content or snapshots and performing the final mix.
