Elecard Sound Level Corrector

Elecard Sound Level Corrector is a GStreamer plugin for calculating loudness of the input signal and adjusting output loudness to not go over the level set by one of the parameters.

Features

Elecard Sound Level Corrector has the following features:

  • Supports 4 sound levels: window shift, momentary, short term, and average;

  • Relies on the LUFS measurement system to show/specify loudness parameters.

Parameter Description

Below is the table describing Elecard Sound Level Corrector parameters and their values:

Controls reference loudness, where:

  • 0—uses loudness estimation for window shift (100 milliseconds);

  • 1—uses a momentary loudness value (400 milliseconds);

  • 2—uses a short-term loudness value (3,000 milliseconds);

  • 3—uses an average momentary value for interval adjustment.
