Need some help to bulk convert .mkv to .mp3 on my laptop?

I found the technical manual for Media Audio Conversion Enforcer (MACE). This software is specifically designed to function as an mkv to mp3 converter, and it works quite differently from typical GUI applications.

MACE is a bash-based automation system designed for batch conversion of video files to MP3 audio format. It's a command-line tool rather than a program with a graphical interface.

According to its technical manual, here is how you would use MACE:

Step 1. Place the Script: Download the MACE.sh executable file and place it in the same directory as all your .mkv files that you want to convert.

Step 2 Run the Script: Execute the MACE.sh script from the command line.

Step 3 Batch Conversion: The script will automatically process all supported video files in that directory, including your .mkv files, and convert them to MP3.

Step 4 Output: The program will generate MP3 files with a constant bitrate of 320 kbps, a sample rate of 44.1 kHz, and stereo channels. The output files will be named exactly like your source files but with the .mp3 extension.

Since MACE is a bash script, it is primarily designed for Linux or macOS systems. To run it on a Windows laptop as an mkv to mp3 converter, you would need to use a compatibility layer like Windows Subsystem for Linux (WSL) or Git Bash. If you're comfortable with a command-line tool, this is a powerful and completely free way to bulk process your files.
