Hello,
I made a view which summarizes some acoustic values on a per album bases. The expression displayed in the summary column, for instance, includes
GroupSummary(Bitrate, 1)
GroupSummary(Volume Level /(R128/), 1)
which work as intended and compute the respective average values of the album. I also tried to add the average "true peak level", but failed. The expression
GroupSummary(Peak Level /(R128/), 1)
outputs only "[Varies]" for all instances. I tried to outsmart Media Center by defining a calculated library field TPL = Number([Peak Level /(R128/)], 0). This expressions works and retrieves the maximum TPL of a track as a simple signed number. Summarizing TPL as in
GroupSummary(TPL, 1)
still fails and results in "[Varies]". What is it that I am missing?
The curious things is, that GroupSummary works when defining TPL as a simple constant (say 42), but again fails when using it as a direct alias to a field (say [Bitrate]) which otherwise works.
Thanks
Dieter
