Crash reports help identify and fix issues, improving the app's performance.

For reporting and assistance, contact us.

Windows crash reports

If you experience a crash on the Windows operating system, the Youlean Loudness Meter may save a crash report.

The location where crash reports will be saved is:

C:\Users\%USERNAME%\AppData\Local\Youlean\Crash Reports

macOS crash reports

On macOS systems, Apple will collect crash reports automatically. The crash reports are stored in the "Console" app on your macOS device.

For more information on how to get a crash report, read this Apple documentation.

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.

Plugin doesn't show in Ableton Live

Once you install the VST3 plugin make sure that VST3 plugins are enabled in Ableton settings.

For more info, read Ableton's documentation.

Plugin and App Measurements are Different

The most likely cause for this issue could be:

• Wrong channel configuration

• The master channel fader is not at 0dB

How to move all meter data to another computer

The user data is stored in the following locations:

Windows:

C:\Users\%USERNAME%\AppData\Local\Youlean\Youlean Loudness

macOS:

~/Library/Application Support/Youlean/Youlean Loudness Meter 2

To move all data, copy these folders to the other computers.

The meter interface is not visible in Garageband

If you open a plugin and you see this:

Make sure that this option is disabled in Garageband preferences:

The meter doesn't show any measurements

The problem might be if the Elapsed histogram mode is selected, but audio playback is stopped.

The solution is to switch to continuous mode for measurements or to activate a host playback.

Youlean Loudness Meter was and currently is developed by a single developer: Julijan Nikolic

The first version was released on November 30, 2016, and development is still going on.

The development was started for the KVR Developer Challenge 2016 competition in which Youlean Loudness Meter got the top votes and first place.

The winning product was then presented at NAMM 2017 in Los Angeles, USA.

Since then, Youlean Loudness Meter has had a lot of new features added.

The Command-Line Tool of Youlean Loudness Meter 2 offers advanced users an efficient way to analyze and normalize audio files, and export reports. To begin using the tool, ensure it's properly installed. You can either manually install it or use an installer to integrate it into your system path for system-wide availability.

Basic Usage:

The tool functions via specific command line arguments. Here's the basic usage structure:

Usage: --input-file-path <path> [options]

Key Commands and Options:

• --input-file-path <path>: Sets the input file path. You can input multiple paths for multi-mono files.

• --preset-name <name>: Selects the preset name for analysis settings.

• --channel-config <config>: Chooses the channel configuration, with 'auto' as the default.

• --export: Triggers the export of reports.

• --normalize: Exports a normalized file.

Examples of Usage:

1. Basic Analysis:

--input-file-path "/your/file/path/file.wav"

ylm2 --input-file-path "C:\example\file.L.wav" "C:\example\file.R.wav" "C:\example\file.C.wav" "C:\example\file.LFE.wav" "C:\example\file.Ls.wav" "C:\example\file.Rs.wav"

This command analyzes the specified file and prints the results.

1. Analysis with Export:

--input-file-path "/your/file/path/file.wav" --export --export-type "PNG"

Analyzes the file and exports the results as a PNG.

1. Normalization and Export:

--input-file-path "/your/file/path/file.wav" --normalize --export --export-type "PDF"

Normalizes the audio file and exports a PDF report.

Analyze folder script

You can download the scripts here and double-click on the script to load it. On macOS, you may need to make the script executable by using chmod +x. Once launched, it will prompt you to specify the folder for analysis. You can drag the folder from File Explorer or Finder, and every audio file will be analyzed, generating a report.

Watch folder script

Set up a watch folder system to organize your audio files into folders for processing, completed tasks, and errors. This helps you efficiently manage your audio analysis workflow.

Double-click the script to start the watch folder process.

Simply insert any audio files you wish to analyze into the ylm2-to-process folder, and the script will automatically process them, moving them to the appropriate outcome folder.

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.

This page offers a comparison between the Free and PRO versions of Youlean Loudness Meter 2.

Live Monitoring

Youlean Loudness Meter 2 standalone app offers Live Monitoring capabilities that allow you to track the loudness of your audio in real time. You will need to set up your audio inputs in the app settings before starting live monitoring. For detailed instructions, please refer to this article on app settings. This feature is particularly useful for live broadcasts, mixing, or any scenario where monitoring audio levels as they happen is crucial.

• Real-Time Monitoring: Launch the standalone app and begin monitoring the audio signal being fed into your system. You will see the Momentary, Short-Term, Integrated, and True Peak loudness levels displayed in real-time.

• Adjusting Levels: Use the visual feedback provided by the standalone app to adjust your audio levels dynamically, ensuring compliance with industry standards and preventing potential issues such as clipping or inconsistent volume.

File Analysis or Normalization

Youlean Loudness Meter 2 standalone app can also be used for File Analysis or Normalization, allowing you to ensure that your audio meets specific loudness targets for broadcasting, streaming, or other purposes.

• File Analysis: Drag and drop audio or video files into the standalone app to analyze their loudness characteristics. This is especially useful for verifying compliance with loudness standards before submitting audio for broadcast or streaming platforms.

• Normalization: Use the Normalization feature in the standalone app to adjust the loudness of your files to meet specific targets, such as -14 LUFS for streaming. This ensures that your audio content is consistent and meets industry expectations.
