This seems almost month old, and without announcement here. I'm quoting help file: Note that if you have selected multiple tracks the DR value will be computed differently depending on the maximum peak difference of the tracks. If the maximum peak difference between tracks is less than 0.3 dB then the DR value is computed with all tracks processed as a single file (Album Mode). Otherwise the DR value is Seems like a completely nonsensical behavoir to me!? As if an album could be identified by similiar peak values of it's tracks... The result is that some albums get scanned in album mode and some in track mode without any possibility to switch between both modes. However, the differences to the offline meter are not due to that album/track mode lottery. Here's another example where the album gets scanned in track mode. Same album, but a different master:dr offline meter results: ************************ ---------------------------------------------------------------------------------------------- Analyzed folder: .\1976 - Songs From the Wood (previous master)\ ---------------------------------------------------------------------------------------------- DR Peak RMS Filename ---------------------------------------------------------------------------------------------- DR15 -0.45 dB -22.92 dB 01.
