Understanding and selecting rms voltmeters - EDN

The ac voltmeter notonly must have adequate bandwidth, but also must faithfully respond to the rms value of the measured noise. Similarly, the voltmeter must have the crest-factor capability to capture the noise signal's dynamic range. Crest factor is the ratio of the peak-to-rms value of the input signal.

1) Connect your voltmeter across the positive and negative terminals of your battery (or power supply). This will measure the voltage across the whole system which includes wiring, amplifiers, speakers, etc.
Sound Card Interface / AC RMS voltmeter - pmillett.com

The true RMS voltmeter section takes the signal from the input buffer and feeds it through an Analog Devices AD536 true RMS converter IC. The output is a DC voltage indicative of the true RMS value of the input. This is sent to an off-the-shelf DPM …

2004-12-31 11:39 pm. #3. There isn't a filter that can make a dc meter read true RMS. dc meters are average reading, they are scaled by 1.11 (the form factor) so that a sine wave of say 1v RMS reads 1v. If you don't have a sine wave, then it's not RMS. Analog Devices make chips that do the conversion, involving log amps and filters.
RMS Level for Mastering: Achieving the Perfect Loudness
https://emastered.com/blog/rms-level-for-mastering
RMS stands for root mean square, is a metering tool that measures the average loudness of an audio track within a window of roughly 300 milliseconds. The value displayed is an average of the audio signal. The RMS value will give you a more accurate look at the perceived loudness of the music track for the average listener.

What’s the Difference Between RMS and “True” RMS? | Tester ...
https://www.tester.co.uk/blog/electrical/multimeter-jargon-busters-true-rms/
When you use a multimeter to measure an AC voltage or current, the reading on the meter is an "RMS" or "root mean square" reading. We sometimes call the RMS value the "effective value" of an AC voltage or current. By that, we mean that the RMS value of an AC voltage or current has the same effect as a DC voltage or current of the same value.
