I’ve been really struggling with submitting decent audio recordings - not loud enough, extraneous noises, too much dead space, etc. Then I found these great guides from the Cornell Lab of Ornithology.
I spent an evening reading them, selecting one of their recommended apps for editing recordings and working through their tutorial on how to use it, and now you can actually hear the bird songs in my submittals. :-)
Also: the metadata on recordings does not transfer when uploading the recordings. A work-around I found on another thread is to take a random photo at the same time as the recording. Make the observation with the photo, which will bring in the metadata. Then edit the observation, remove the photo, and add the recording. The metadata will be retained even after the photo is deleted.
I highly recommend recording through the Birdnet app. Not only do you see a spectrogram, you can select a range, save that clip as an observation, and export it to iNat. Unfortunately, none of the metadata exports, so you have to manually enter the time, date, and location fields, but it gets the audio file into an iNat observation.
Thank you for those resources for better sound files! I’ve been trying to make more sound files OBs this year, so these are helpful.
OTOH, I believe iNaturalist does not really like to have random photos uploaded to a record to provide meta data and stored on iNat because it could impact the CV training protocols.
So, I think what you can do to avoid that is some version of:
upload the random photo to pick up the metadata
upload your sound files
then delete the random photo after making your record.
