@Robert Manzano Interesting. Yes, that was how I specified parallel cores in my script, which seemed to work well. Perhaps try bumping up the number of cores and see what happens. Thanks for the advice re SNR. I have considered this, however perhaps re-visiting it in a more detail will help. Cheers and good luck. Chris G

Hi Rob Good to hear that you’re also trying to analyse bird data using warbleR. It was taking me 5-6h to process ~ 3300 1min audio clips. I was using four parallel cores (using the “parallel” call to do this, say in the “autodect” function) on my computer, however I imagine you could quicken the processing time considerably if you have access to a larger processing computer by specifying more cores. I imagine that processing speed also relates to the size of your files, so this is a consideration too. Out of interest, how are you processing your bird calls? My aim is to build a model to predict specific bird calls within my sound clips (i.e. present / absent), using data from Xeno-Canto and my own recordings as training data. To date, I have been able to extract the relevant information using warbleR and then build a good Random Forest model which predicts well on the training data. My problem is that this model has poor predicative accuracy on my testing data; that is, the 3300 audio clips I want to predict calls on. I assume the problem relates to the fact that I am not including enough different types of “no” calls in my training data, which would explain why my model is performing well on my training, but not testing, data. Anyway, hope this helps Cheers Chris G

Thank you for the advice Jan. Given your help I've now been able to find event-windows in my AudioMoth data (i.e. step one of my workflow). My problem was that I was focusing on the Freq and Duration attributes in autodetect and not so much on the Amplitude attributes. I found that I was able to reliably detect my event-window by fine-tuning the "threshold", "ssmooth" and "wl" attributes (see attached). Again, thank you for your help
