After updating to 1.3, Roon will re-extract file tags from your library and then re-queue your files for audio analysis. This can place some extra load on your core until that work is complete, so consider this when deciding when to accept the update.
Starting in Roon 1.3, we have fully adopted the R128 volume leveling standards. Your music library will be re-analyzed automatically to extract R128 data, and the volume leveling features throughout the app will make use of it.
Finally, Roon’s Audio Analysis can now be configured to use all of your CPU cores, and several stability issues related to analysis have been addressed.
