RMS Normalization - Hack Audio

When performing RMS normalization, it is possible to scale the amplitude of a signal such that the peak magnitude is greater than 1. This will cause the signal to be clipped, or distorted. This can occur even if the RMS …
How to normalize audio? Why do it? Everything you need to know

In digital audio you can’t get any louder than the highest peak at 0 dBFS, so normalizing to this value will create the loudest file you can. RMS volume detection This considers the “overall” loudness of a file. There may be large peaks, but also softer sections. It takes an average and calls that the volume.
Root mean square normalization in ... - Ayoub Malek’s Blog
https://superkogito.github.io/blog/rmsnormalization.html
Audio normalization is a fundamental audio processing technique that consists of applying a constant amount of gain to an audio in order to bring its amplitude to a target level. A commonly used normalization technique is the Root Mean Square (RMS) normalization. This blog post introduces RMS normalization and provides a Python implementation of it.
Normalizing audio waveforms code implementation (Peak, RMS)

x t r a n s f o r m e d ( n) = c × l o g ( 1 + x ( n)) Where c is a normalisation parameter. Due to its shape the l o g ( ⋅) function will boost small amplitude values and limit high amplitude values. To get a feel about how the waveform might look like, you might want to have a quick look at the way Audacity does its 'dB View' of waveforms.

Find and select new plugins. Click Enable. Click OK. Now the RMS plugin will appear in the Effect menu and the ACX plugin is going to be available under the Analyze menu. N. B. Since version 2. 4. 2 (or maybe even earlier, I don’t know for sure) they’ve incorporated a stock RMS normalizer called LOUDNESS NORMALIZATION.

One popular quick and simple solution is to simply apply the hyperbolic tangens function (tanh). This will limit values to [-1, 1] by penalizing higher values more. If you amplify the signal before applying tanh, the effect will be more pronounced. Another alternative is a logarithmic transform.

ffmpeg -i (inputfilename) -af "normalize_rms=-20dB" (outputfilename) Explanation of Conditional Statement and Example: Pass 1: run astats or volumedetect to calculate RMS level. Pass 2: If RMS level = X dB, then add Y dB level to match the user specified dB level. Example: If RMS level = -30dB, and user specified RMS level = -20dB, then add 10dB. audio ffmpeg …
