    Bit of an odd title but I'm looking to cut some corners to simplify a design...

    I'm building a new bat detector (frequency division same as before) but its going to be alot more compact and use fewer components. I have some quad op amp ICs and was wondering if I could get away with just using one of them (dual rail so one of the amps will be used in teh splitter).

    The general idea of the thing is something like this:
    electret > amplifier > high pass filter > comparator > counter > speaker

    - Does it really need a 'normal gain stage' since a comparator is basically maximum / infinite gain?
    - Do I need buffer stages or can I use a non-inverting amp etc?
