Understanding what does RMS stands for in Audio ...
https://www.audiorecording.me/understanding-what-does-rms-stands-for-in-audio-definition-details.html
Between the minimum (the quietest sections of the audio) and the loudest section (towards 0dBFS, the peak) is where the RMS value can be found. …
RMS Amplitude - Hack Audio
https://www.hackaudio.com/digital-signal-processing/amplitude/rms-amplitude/
An analysis used for the overall amplitude of a signal is called the root-mean-square (RMS) amplitude or level. Conceptually, it describes the average signal amplitude. However, it is different than simply measuring the arithmetic …
RMS value of audio signal - Page 1 - EEVblog
https://www.eevblog.com/forum/projects/rms-value-of-audio-signal/
You dont need to calculate RMS if you only want to test against threshold. If you really want RMS value (root of mean squares) just take square root of the average power. But as i said you can as well square your threshold and save computing power of the square root... Logged Good enough is the enemy of the best. rakeshm55 Regular Contributor
RMS Level for Mastering: Achieving the Perfect Loudness
https://emastered.com/blog/rms-level-for-mastering
What is RMS? 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 Is RMS? -What Does RMS Power Rating Mean In Speakers?
https://www.carelectronix.com/what-is-rms-what-does-rms-power-rating-mean-in-speakers/
RMS (Root Mean Square) is the preferred method of obtaining power measurements for audio signals. The idea behind it is to give you an idea of how powerful your sound system will be perceived by the audience/listener. This means that the human ear perceives lower sound levels than what they are actually exposed to.
Average RMS value of an 3D audio signal in Python - …
https://stackoverflow.com/questions/25324399/average-rms-value-of-an-3d-audio-signal-in-python
The RMS of is signal is the root mean squared, which is not the same as the mean. So you need to perform the RMS calculation. math.sqrt(numpy.mean(x*x)) There are several other pages on this site that discuss this in further: here, here, here
What is "RMS (Root Mean Square)"? - inSync
https://www.sweetwater.com/insync/rms-root-mean-square/
RMS is (to engineers anyway) a meaningful way of calculating the average of values over a period of time. With audio, the signal value (amplitude) is squared, averaged over a period of time, then the square root of the result is calculated. The result is a value, that when squared, is related (proportional) to the effective power of the signal.
how to calculate rms of an audio file - MathWorks
https://www.mathworks.com/matlabcentral/answers/399348-how-to-calculate-rms-of-an-audio-file

Significance of RMS (Root Mean Square) value - …
https://www.gaussianwaves.com/2015/07/significance-of-rms-root-mean-square-value/
RMS value of a signal is calculated as the square root of average of squared value of the signal. For a complex-valued signal set represented as discrete sampled values – , the mean square xRMS value is given as Applying Parseval’s theorem, the root mean square value can also be computed using frequency domain components X [k]
audio - Getting loudness of a track with RMS - Signal ...
https://dsp.stackexchange.com/questions/290/getting-loudness-of-a-track-with-rms
Would I simply sample for one second (audio[0] - audio[44099], audio[44099] - audio[88199] etc..) and calculate the RMS of those values? So, for example, would I do this: $$RMS = \sqrt{\frac{\text{audio}[0]^2 + \text{audio}[1]^2 + \text{audio}[2]^2.....\text{audio}[44099]^2}{44100}}$$
