LUFS Metering

The LUFS scale is a measurement of loudness units that are designed to identify the loudness and true-peak level of audio. The loudness unit measurement system is biased to the real perception of audio. A loudness unit is equivalent to a dB. The LUFS scale is capable of balancing multiple audio sources at the same…

Stereo Separation Metering

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

VU Metering

A VU (volume units) meter is a tool that displays an average signal level, as it allows the user to perceive louder sounds. The first known VU meter was created in North America and was called SVI, short for Standard Volume Indicator. The name originally emerged because the meter scale was calibrated in volume units.…

Spectrum Analyzer

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

Spectrogram

An audio spectrogram is a visual representation of a sound. A spectrogram is an extremely sophisticated audio analyzer that 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 time. Spectrograms, sonograms, voicegrams, and…
