British Trust for Ornithology (BTO)
Accompanying an article in British Wildlife describing the sound identification of small terrestrial mammals in the UK, colleagues and I at the BTO have put together a sound library (wav files and playable spectrograms - in 10 x time expansion), which are free accessible via www.bto.org/small-mammals.

Stuart, that is really cool! Are these clips translated into audible frequency range?

Hi Phil, the playable spectrograms have been translated into the audible frequency range (by playing in 10 x time expansion), becuase the small mammal calls are mainly above our hearing range, but a copy of the original wav files can be downloaded from the web site.

Ah, perfect. I was wondering why I never hear those calls!
That's really nice work, thanks so much for sharing!
