Nov 1, 2022 at 19:02 comment added Taiki Sakai @lframond yes, that can also work but you need to make sure you apply the appropriate filter before downsampling to make sure your results do not have any aliasing. Just adds extra processing steps
Oct 17, 2022 at 6:59 comment added lframond what about down-sampling the recordings to 10 kHz? This would automatically make spectrograms that are truncated to 5 kHz... would that be a solution and if not, why?

Jun 28, 2022 at 0:07 comment added Taiki Sakai I'm not sure if you can do it in something like Raven or Audition, but it should be very easy to do in whatever programming language you are using for your machine learning model. You'll need to have the spectrograms as a matrix at some point (either by creating it from the waveform or reading it from an image), so you can just subset that matrix for only the rows with frequencies you are interested in
Jun 27, 2022 at 7:42 comment added Potichien Thanks for this! Truncating the spectogram is actually what I originally wanted to do but I could not find how to do it, either on Raven or Audition. Do you have a link to a tutorial or something that could help? I'll think about your comment on the harmonics, thank you for this
