Hi Mike,

I would agree that it is a Pipistrelle bat. The Soprano Pipistelle  has a h=
igher end frequency ("QCF") ranging between 53 and 60 kHz. The maximum freq=
uency (at the beginning) of a bat call is more difficult to determine becau=
se the results would strongly depend on the specific recording situation an=
d the frequency response of the microphone.

There is a table of the frequency ranges of European bats available at www.=
batecho.eu:

According to this table, your end frequency of 46 kHz fits very well the li=
mits between 41 and 50 kHz.

Regards,
Raimund
