To understand us &#8230; If we have, for example, a recorded song where a drummer emphasizes playing the tarola or a cymbal, we will see that our peak meter will show a higher value for a moment, because it is the one that is sounding louder in that instant. This meter will work with fast attack times, to be able to immediately measure these peaks and maybe use a limiter to avoid them.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_RMS\"><\/span>What is RMS?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The RMS value, however, will mark the average value of the loudness or volume of our music &#8230; how does that do it? , for this it will use attack times, much longer longer. To be clearer &#8230; This value will give a reference of the energy level or volume (how high or low is the volume that is playing) but will not be affected by the peaks.<\/p>\n<p>When we say that it has a slower attack value, this means that it does not measure variations so quickly, but rather that it is &#8220;slow&#8221; to react and therefore shows us something that could be an &#8220;average&#8221; volume level.<\/p>\n<p>In any case, the suitable normalizer must be a mixture of limiter (that device that prevents the music from distorting because it has exceeded the maximum possible level) and a compressor, which is the one that prevents the peaks from exceeding a level and also prevents them from Volume drops drop more than a preset value.<\/p>\n<p>In this way the music always remains within a medium range, without exceeding a limit neither up nor down.<\/p>\n<p>Professionally recorded or broadcast music is always limited and compressed to keep it playing its best within a suitable range.<\/p>\n<p>The only software that does exactly this is the Mp4Gain.
