How to calculate loudness in Matlab?

Measure Loudness and Sharpness of Stationary Signals

fs = 48e3; dur = 5; pnoise = 2*pinknoise(dur*fs); wnoise = rand(dur*fs,1) - 0.5; wnoise = wnoise*sqrt(var(pnoise)/var(wnoise)); Call acousticLoudness using the default ISO 532-1 (Zwicker) method and no output arguments to plot the loudness of the pink noise.

How is integrated loudness calculated?

loudness — Integrated loudness (LUFS)

The ITU-R BS. 1770-4 and EBU R 128 standards define the integrated loudness. The algorithm computes the loudness by breaking down the audio signal into 0.4-second segments with 75% overlap. If the input signal is less than 0.4 seconds, loudness is returned empty.

Can Matlab produce sound?

To produce a sound and specify its pitch and duration in MATLAB^®, use the sound function.

What are LUFS in music?

LUFS stands for Loudness Units relative to Full Scale or Loudness Units Full Scale (i.e., the maximum level a system can handle.) It's a standardized measurement of audio loudness that factors human perception and electrical signal intensity together.
