Hello all,
I was just wondering if anyone knew of any programs or AI technology that I could use to sort through my audio recordings? I am a young researcher, so I have little experience in the field. I am looking to also find a program to ID bird sounds or animal sounds in general.
As Alex Rogers has already said, The BTO's Acoustic Pipeline tool is very effective for Bats & small Mammals. However, before uploading my recordings, I run BatClassify against the files (I generally set the time length to 15 secs) and it is fairly accurate in identifying the files containing Bat Sounds. The results are presented as a .csv file which I take into Excel and then I use a formula to determine which are worth uploading (from hours and hours of practical experience only those files with a score over 80% are worth processing further).

When uploading Bat recordings, the Acoustic Pipeline tool will identify that a Bird is present but will not identify the species. It is however pretty good for Bats and small mammals, though I usually visually check the files for unexpected species, once I've received the results of the analysis. Some of the regional Bat groups in the UK have done their own studies on the accuracy of the various recording tools and analysis software for bats.
There are separate services available via the Acoustic Pipeline upload tool, which focus mainly on nocturnal birds - either nocturnal breeding birds (Owls, Nightjars etc) or Nocturnal migrating birds (Thrushes, waterfowl etc). I have been mainly selecting these files visually, but have not yet found a bird equivalent of Bat Classify, to help simplify that process.
Acoustic Pipeline gives you 100Gb upload limit per year for free. If you need more than that, that you can buy extra units.
