Sonograms

So it was pointed out to me that the sonogram that I posted yesterday needed zooming in to reveal detail, so I've had a play on Raven Lite again and zoomed in to reveal detail, but also compared the original recordings sonogram and the edited versions.

Original Sonogram

Edited Sonogram

Although the sonogram has a little less 'interference' on the edited version I think the original shows the shape of the call better than the edited version, something worth bearing in mind when producing future sound recordings.

Also had a look on Xeno Canto at Bullfinch recordings

Doesn't take long to realise the variation in the calls of the 'Eurasian' Bullfinch, also never realised how many ssp there are!
