Re: sum-of-magnitudes estimate

Any thoughts on which of the above are "best" in some cosmic (or perhaps
even RMS ;-) sense? Anybody got any better way to do this, where
"better" is defined as "more accurate, but still pretty computationally
light"?
===========================
I have calculated and graphed the average and rms of many speech and
music waveforms, and the rms always seems to ride about 2dB above the
average. This is personal observation. You might observe different, but
its easier to calc the avg and add 2dB!
