Oh, how do you convert from WPEP to WRMS? Does it have to be converted to
voltage and multiplied by .707?

Chris


While the conversion from PEP to RMS is simple for a sine wave or other
simple waveform, it's not simple when dealing with a real voice
waveform. It depends heavily on the characteristics of the voice, and
any audio processing (such as compression or RF clipping) that might be
taking place. Typically, the PEP value of an unprocessed voice waveform
is many times the RMS value.
