Ok, so who knows a bit about measuring audio power ? Setting aside any
furious arguments about peak power, rms power, average power, backpeddling
average peak music power on any given friday in March etc, does an audio
power meter sum the power in both half cycles to arrive at a reading, or
just one.

I guess what I'm asking is half wave reccy ahead of the meter, or full wave
bridge ?

** The phrase " audio power meter " is not defined.

** AC voltage meters are usually full wave.

True RMS types certainly are.

Or are you really asking about programme level meters like VUs and PPMs ?

The type of rectifier doesn't make a great deal of difference,
although full wave probably has the edge on accuracy. Don't put a
capacitor after it, just let the meter do the averaging, then do the
sums: power = v squared / R.

There are audio power meters that approximate true RMS for greater
accuracy, but they are from the prehistoric era before we could do all
that stuff digitally.

If you really want to measure power accurately, use a resistor as the
load, and measure its temperature.

** Sure - average rectified sine wave value is *just fine*.
