Questions - Animal Cognition 2016 - Elie/Theunissen

[Rachine]

Hello Pr. Theunissen,

I have several questions around your Paper in Animal Cognition 2016 with Julie E. Elie "The vocal repertoire of the domesticated zebra finch: a data driven approach to decipher the information-bearing acoustic features of communication signals".

First, I have a question about the pre-processing of the audio wav files: How can we go from the raw data with 2969+464=3433 stereo wav files with varying size into the segmented mono wav files of around 180 ms with 8136 calls from 45 birds? I am referring to the part from the subsection "Vocalization Preprocessing and the Generation of the Vocalization Data Base" in your paper.

Concerning the database, how is it possible to know the 'Sex' of the adult Zebra Finches?
I also found some WC call entry in the database, is it Whine Call or Wsst Call?

Besides, if I well understood your validation strategy is similar to the GroupShuffleSplit strategy (see image below), Group being the bird and class being the Call type. Is this is correct?

This is so great that you shared so much data and code resources on github. Thank you very much!

Best
