Bill,
No these are wav files, I have been using Anabats with Analook, but
the first proptotype of our new bat detector should be up and "sort
of" running in a week or so and it uses wav files saved to an SD
card.
However, I didn't realise yuu could constrcut a filter with Analook,
and as I am still using Anabats I will give that a look.
Thanks,
Graham
