Unhappy Question about measurement features

Hi,
Is there a Raven measurement that calculates the amount of a selection (or bin) that is taken up by sound or has sound readings in it? I would like to find a way to run the analysis described below on Raven.

Acoustic Diversity Index from Villanueva-Rivera et al. 2011. The ADI is calculated by dividing the spectrogram into bins (default 10) and taking the proportion of the signals in each bin above a threshold (default -50 dBFS). The ADI is the result of the Shannon index applied to these bins.

Thank,
Adrienne

Hi Adrienne,

We do plan to include this Acoustic Diversity Index in a future release of Raven Pro. However, that isn't likely to happen in the next few weeks.
