![]() It works in a similar way to the human ear. It has a slow response and ignores the signal peaks (300 milliseconds of integration time). VU meterĪ Volume Unit Meter is a metering unit to measure a signal level volume. RMS meters are used for statistical measurements of the overall volume and are very useful for mastering purposes. RMS value is represented by the root mean square of the signal, so the values don’t react as fast as a peak meter it represents an average of the total volume. These meters are usually found in most DAWs, and becomes very useful (in conjunction with a VU Meter) for recording purposes, to avoid digital clipping. PPM meters are usually fast and react to all transients in the audio signal. Peak value is the maximum wave amplitude measured in dB (decibels). Peak, RMS, and VU meters were all designed with different purposes in mind let’s examine the differences and discuss when to use each of them. We have our own standard that will both help organize our work and get rid of volume problems between tracks. ![]() The mastering engineer’s job will be easier.Once we understand the basic concepts around these different types of metering, we can obtain better results and optimal headroom. We often tend to use the same process ITB, as if it were an analog console, but most DAWs only have peak meters and these are not useful when mixing. When we mix ITB (in the box), usually, we don’t have a volume reference starting point. Having optimal headroom is mandatory in order to obtain a great mix. In this article, we will discuss gain staging and levels in the mix, explain peak values, RMS, VU, and detail on how to obtain optimal headroom in the box. ![]()
