[rrd-users] Average of sound levels

[Peter]

Hi,
it is possible to store sound levels in a rrd database an calculate the
correct average?

This excel Matrix formula (enter in A1 with ctrl+shift enter)
=10*LOG10(AVERAGE(10^(0.1*(B1:C8))))
calculate the average sound level of cells B1:C8

The RRA command has only the aggregate functions AVERAGE, MIN, MAX, LAST
It is possible to add a custom function LAVERAGE?

Peter
