Re: [nfc-l] Mystery Calls

Ah, that makes sense. Is there no way to extend what the detector pulls?

The original call on this thread sounds a lot like a goldfinch to me.

Re: [nfc-l] Mystery Calls

2017-05-02 Thread Jay McGowan
Hey all,
I've posted this before, but I would implore folks posting example
recordings to this list to leave a few seconds of sound before and after
the call in question so you can actually hear it. With only a second-long
recording, all I hear is a burst of sound with no time for my ear to
acclimate to the background noise. The same goes for audio upload to eBird.
We suggest leaving three seconds, if possible, before the first and after
the last vocalization in the recording before upload.

Thanks!

Jay

Re: [nfc-l] Interesting Calls

2016-09-23 Thread Jay McGowan
Hi all,
I just wanted to post a reminder that when sending out flight calls for ID,
some of us would really appreciating your leaving a second or two before
and after the target sound. This really helps a lot when trying to actually
listen to the recordings, as it can end up sounding like just a wall of
sound otherwise, with the target voc impossible to pick out of the noise
without some introduction first. Boosting the gain (normalizing) the clip
would also be helpful in many cases. Both of these are also very important
for prepping recordings for upload to eBird, if that is something anyone on
here is interested in doing.

Thanks!
Jay

Re: [nfc-l] Barn Owl Candidate - Etna, NY

Very cool, Chris! Here is my eBird report from Friday night with details of
my owl, for those interested. No recordings, unfortunately.
