iZotope RX Loudness Control

If you use Adobe Media Encoder, Adobe Premiere Pro or Pro Tools to mix and process audio tracks, you might want to try iZotope RX Loudness Control, a plugin capable of correcting global loudness automatically. It also works by importing video clips to handle audio settings.

The tool can analyze a complete audio mix to determine the volume level, inform you if it's compliant with the loudness standard you specify, and normalize it if necessary. Once it's done, it generates a CSV file with logging details.

Although the loudness standard is customizable, iZotope RX Loudness Control comes bundled with several presets: AGCOM 219/09/CSP, ARIB TR-B32, ATSC A/85, BS.1770-1, BS.1770-2/3, EBU R128, EBU R128 DPP, EBU R128 s1 - Momentary, EBU R128 s1 - Short-term, and OP-59. Their integrated, tolerance, short-term, momentary, true peak and gating parameters are included in the help file.

Four tabs can be accessed for applying effects, handling audio, entering authorization details, and setting publishing options. For example, you can enable a time tuner and cut the audio duration, pick a preset for the loudness standard or customize parameters, configure the true peak limited, and ask the tool to write the previously mentioned CSV report.

Audio properties can be edited when it comes to true pick, integrated, loudness tolerance, and short/momentary loudness. You can also use a loudness gate and save history to CSV.

Once you're pleased with the entire project, you can export it to various media platforms, like Adobe Creative Cloud, Behance, Facebook, any website via FTP, Vimeo, or YouTube. The export options depend on the VST host you're using.

The tool worked smoothly with Media Encoder in our tests. Taking into account its advanced settings and intuitive interface, iZotope RX Loudness Control comes in handy for verifying the loudness level of music files and normalizing it if necessary.
