it is worth thinking of devices as microphones with built in recorders, rat=
her than recorders with built in microphones. the nagra ares, as far as i k=
now,=A0 tried to do this. i wish more would, and at much lower=A0price poin=
even record level is not needed, just three sensitivity positions. headphon=
es and simple monitoring for levels. removable sd cards means not even a us=
b connector is needed. just space for some batteries.
