Hi Laura,

another possible explanation for the effect would be that you perhaps used =
a compressed file format such as mp3 (or mp2), which can also create simila=
r artifacts. If so, you should use instead the uncompressed .wav file file =
format.

I was using manual gain (no automatic), but I had some difficulty getting c=
lose enough to the birds for a clear signal and then having them shift posi=
