Hi everyone

Thanks for all your help -- I am now following a set of steps that minimizes my 
workload while allowing me some manual input to sort through "good" and "bad" 
calls. I (a) label each call section manually in the spectrogram window (set on 
"autogain" to reduce the bias of varying amplitudes), (b) save the file to keep 
the labels intact, then eventually (c) run a batch process to obtain all the 
measures I'm interested in, using the automatic measures feature of Avisoft, 
and (d) run a batch process to save the labeled calls/ elements as separate 
.wav files for further analysis in a different program.

Thanks again -- this is my first interaction with a usergroup like this, and 
has been a very positive experience.
