Nine months later, in December, a friend of mine was in north Florida attending the 2011 BFRO expedition. I suggested she check out the place where I had success with my recorder in March, and she spent 3 nights camped out and recording on her way home from the expedition. Happily, she too recorded some great vocals, better even than the ones I recorded. Her clip includes a moan howl, two whoops, some wood knocks, and a long wavering howl. But what's also notable in her clip is the voice of the main vocalizer. It sounds very similar to the vocalizer I recorded in March.
Here's a video-spectrogram that replays both clips and makes it easier to compare one clip to the other, while also highlighting some of the vocal features in each recording. I postponed publication of this post because I was just in Decatur County last week, hoping to record a third performance. But sadly that didn't happen, so there was nothing new to add to this video.
Nicely done as always.
ReplyDeleteI was just about to ask you how the trip went. Sorry you didn't catch anything that stood out this time but the others from last year are just incredible. I'll bet there is something really faint on your recordings of the latest trip though. Is there a way you can check other acoustic ranges usually outside of the norm? Just curious. Will email soon; need your expert opinion on some things.

Good question hankd. And what I normally do is use a spectrogram to study the captured audio. I open the view wide enough to see frequencies that include the expected vocal range, and then a little bit higher, too (to spot things like high shrieks or whistles). You're probably right. If I go back through my audio with a fine toothed comb, I probably would find a faint vocal or two. Just haven't had the time to scrutinize that closely yet. I'll keep an eye out for your email!
