I forgot to mention that I can hear a ringing sound when I play the 1/5 speed
Skylark. I did a spectrum analysis in Audactiy, and it's about 4400Hz, i.e.
close to 1/10 of 44.1kHz. Is this some sort of artefact from slowing it down?

I agree, it's a little out of synch. The full speed version might be too, but
it moves so fast it's hard to be sure.
Chris, how do you get your spectrograms so clean? Is that the results of them
being cleaned up somehow, or is it because the recordings are clean? Mine are
from a SASS style array, so there's lots of background noise making the
spectrograms speckly.

What a lovely website Chris!
I had a quick look & listen to 2 species with sonograms, your system
seems to work well. But for the Skylark at one-fifth speed the
sonogram started to lag behind towards the end. Not a criticism,
just an observation on the technologies we are discussing.
