WebWhen 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 normalization is less than 0 dBFS RMS. The next step after processing a signal by a single number is to look at how we can ...
