LUFS Metering

The LUFS scale is a measurement of loudness units which identify the loudness and true-peak level of audio. LUFS stands for Loudness Units Full Scale. Nevertheless, before it was invented, there were some troubles to correctly indicate this subjective perception of sound. In the following lines I will explain LUFS metering and how it came…

Goniometer (Stereo Separation Metering)

The Goniometer, also known as an Audio Vector Oscilloscope, is an instrument that offers a complete image of the relationships within a stereo signal. It is a tool that shows the stereo separation signal measurement within the audio metering world. Its main task is to plot the signal on a two-dimensional zone so that the…

VU Meters

VU stands for volume units—and VU meters are tools that display an average signal level, as they allow the user to perceive louder sounds. VU meters have a moving needle on a graduate scale. The upper part of the scale is calibrated in dB, and the lower one in percentages. Volume is quite subjective since…

Spectrum Analyzers

Spectrum analyzers are a specific type of sound level meter. They allow the user to study the amplitude versus the frequency spectrum of any given sound. These analyzers use a wide variety of filter networks and vertical columns that show the data organized on a specific range. The range goes from low frequencies to high…

Spectrogram

An audio spectrogram is a visual representation of a sound. In other words, it is an extremely intricate audio analyzer. As a result, it provides a very detailed and accurate image of audio. A spectrogram is a time-varying spectral representation that has a wide diversity of spectral density of any given signal with respect to…
