Blu-ray discs offer incredible audiovisual experiences, but there are times when you may want to add or replace an audio track in a Blu-ray BDMV folder. This can include adding a new language, commentary, or improved sound quality to your favorite movies or personal projects.

This article will guide you through two effective methods for adding or replacing an audio track in a Blu-ray BDMV folder. The first method uses TsMuxer to make quick changes without preserving menus, while the second utilizes Yuhan Blu-ray Creator to make adjustments while maintaining full menu functionality.

Part 1. Add or Replace an Audio Track for a Blu-ray With TSMuxer

TsMuxer is a powerful tool that enables users to demux and remux Blu-ray content. It's especially useful for making quick modifications such as replacing or adding audio tracks without re-encoding the video, ensuring no loss in video quality. However, using TsMuxer will strip the Blu-ray menu from your project, resulting in a simple playback experience.

Key Features of TsMuxer

• No Re-encoding: Avoids quality loss in video and audio.
• Fast and Lightweight: Makes modifications quickly.
• Free and Open-Source: Ideal for users on a budget.

Limitations of TsMuxer

• No Menu Support: Blu-ray menus are lost during the process.
• Limited Customization: Lacks advanced options like chapter editing.

Step-by-Step to Add or Replace an Audio Track for a Blu-ray with TsMuxer

Step 1: Download and Install TsMuxer

• Visit the official TsMuxer website(https://www.videohelp.com/software/tsMuxeR) and download the latest version for your operating system.
• Install the software and launch it.

Step 2: Load the Blu-ray BDMV Folder

• Open TsMuxer and click on "Add" to load the main movie file from the Blu-ray BDMV folder (commonly found in the STREAM subfolder with a .m2ts extension).
• TsMuxer will automatically detect all streams (video, audio, subtitles) in the file.

Step 3: Replace or Add the Audio Track

• Deselect the existing audio track you want to replace.
• Click "Add" and browse for the new audio file (e.g., a .dts, .ac3, or .wav file).
• Ensure the new audio track is synced properly with the video. You can adjust the audio delay if needed by entering a value in the "Delay" field.

Step 4: Create a New Blu-ray Structure

• In the Output section, select "Blu-ray ISO" or "Blu-ray folder" as the output format.
• Choose a destination folder for the remuxed Blu-ray.
• Click "Start Muxing" to begin the process. TsMuxer will generate a new BDMV folder or ISO without the original menu.

When to Use TsMuxer

TsMuxer is perfect if you:

• Do not require a menu.
• Need to make quick modifications without compromising video quality.
• Want a free, straightforward solution.
