Can anyone identify this night time bird?

Having our windows open last night we first heard a typical  tawny owl sounds and calling that we hear every so ofter but after that we heard about five minutes later this bird, it moved gradually towards to house and at one point sounded like it was in the trees just over the way, the audio even picks it up reverberating off the houses

This was about 10:45pm, constantly for about 15 minutes and then completely stopped, didn't even sound like it moved away
