EZ Meta Tag Editor

Automatic check for updates

Automatically connects to the update server and notifies when a new software update is available.

Play a sound when a task is completed

Plays a notification sound when ReplayGain scanning is finished.

Quick Edit metadata fields

When enabled, enters edit mode directly in the file list with a single click. Just a click on a metadata field, and it becomes editable in place.

Number of parallel EBU R 128 | ReplayGain scanners

Sets the number of parallel scanners used for audio analysis.

Loudness display units

Loudness

Chooses how loudness values are shown across the application. This setting controls the unit used when displaying track and album loudness

• LUFS (Loudness Units relative to Full Scale):
  An industry-standard EBU R 128 measurement used in broadcasting and streaming.
• ReplayGain Δ:
  Displays the gain adjustment needed to reach a reference loudness. Useful for understanding how much a track will be boosted or reduced during playback.
• ReplayGain SPL:
  ReplayGain reference loudness (SPL - sound pressure level) based on ReplayGain analysis.

Peak

Chooses how peak levels are displayed throughout the application. This setting controls whether peaks are shown as a percentage or in decibels.

• Percent (%):
  Displays the peak level as a percentage of full scale (0–100%). This format makes it easy to spot how close a signal is to clipping.
• Decibels (dB):
  Shows the peak level relative to full scale (dB FS/TP), where 0 dB FS/TP represents the maximum possible level. Negative values indicate how far below clipping the peak is, offering more precise technical insight.

EBU R 128 | ReplayGain Algorithm

Controls how loudness and peak values are calculated when analyzing audio. It affects both normalization accuracy and how closely playback matches perceived loudness.

Loudness Algorithm Options

• Integrated
  Measures the average loudness over the entire track or album. This is the standard method defined by EBU R 128 and provides consistent, reliable results for most use cases.
• Top of Loudness Range
  Focuses on the louder sections of the audio instead of the full average. This can better reflect how loud a track feels during its most prominent moments, which may be useful for dynamic material.

Peak Measurement Options

• Sample Peak
  Calculates peak levels based on the actual digital samples in the audio file. It is fast and commonly used, but may miss peaks that occur between samples.
• True Peak
  Estimates the real peak level of the audio signal by accounting for inter-sample peaks (what happens after digital-to-analog conversion). This provides more accurate detection of potential clipping, especially for lossy formats or playback systems.
