After installing the plugins, you need to load Youlean Loudness Meter 2 inside your preferred DAW. The following plugin types are supported: VST2, VST3, AU, AAX.

• Placement: The plugin should be placed at the last position on the master mixer bus.

• Enable Playback: Once the plugin is inserted, enable playback by pressing play in your DAW to see the loudness measurements.

Note: The master fader must be set to 0dB, as it applies volume correction after all plugins in the mixer chain, which can lead to inaccurate loudness measurements if not set properly.

Youlean Loudness Meter 2 is engineered to be compatible with a wide range of systems, ensuring that users across different platforms can access its advanced loudness metering capabilities. Below are the system requirements needed to run Youlean Loudness Meter 2 effectively.

Operating Systems:

• macOS: Supports Version 10.13 (High Sierra) or later, compatible with both Intel x64 and ARM64 architectures (Intel CPU, Apple Silicon, M1, M2, M3).

• Windows: Compatible with Windows 7 or higher, supports both 32-bit and 64-bit Intel/AMD systems.

Formats:

Application (Standalone): Available for both macOS and Windows. This standalone version allows easy access and usage without needing a DAW.

Command Line Tool: For users who prefer script-based control or automation. This tool offers advanced capabilities for integrating into custom workflows or automated systems.

Plug-in Formats:

• VST2: For DAWs supporting the VST2 standard.

• VST3: Compatible with newer VST3 standard DAWs.

• AU (Audio Unit): Specifically for macOS, works with AU-supporting DAWs.

• AAX: Designed for Avid's Pro Tools.

Youlean Loudness Meter 2 is equipped with a comprehensive set of measurements essential for audio production and broadcasting. Here's an overview of its key measurement capabilities, including those specific to dialogue:

Momentary Loudness (LUFS):

Measures average loudness over 400 milliseconds, ideal for monitoring rapid loudness fluctuations.

Short-term Loudness (LUFS):

Averages loudness over a 3-second period, useful for evaluating specific parts of a track, like verses or choruses.

Integrated Loudness (LUFS):

Calculates the average loudness over the entire duration of a track or segment, essential for broadcasting and streaming platform compliance.

True Peak Level (dBTP):

Detects the maximum level of audio signal peaks to prevent digital clipping and distortion.

Loudness Range (LRA):

Measures the difference between the quietest and loudest parts of a track, indicating its dynamic range.

Average Dynamics (PLR):

This ratio reflects the difference between the peak level and integrated loudness, providing insights into the overall dynamics of the track.

Dynamics (PSR):

Offers real-time insights into the dynamic processing of the audio by measuring the instantaneous difference between peak and loudness levels.

Integrated Dialogue Gated Loudness:

Specifically measures the integrated loudness of dialogue within a program. This is crucial for content where dialogue clarity and consistency are key, such as in film and TV production.

Dialogue Gated LRA:

Calculates the loudness range of dialogue content by focusing on the parts where dialogue is present. This measurement is vital for understanding the dynamic range of speech in mixed audio content.

Dialogue Percentage:

Indicates the percentage of the program's duration that contains dialogue. This metric is particularly useful in assessing the balance between dialogue and other elements in the audio mix, such as music or sound effects.

Special thanks to all the testers who have helped over the years!
