Convert just the audio in a video file to AAC for compatibility.

audio-fixer

The audio-fixer.sh script is designed to process video files by copying the video stream (leaving them untouched) and converting the audio stream to 160kbps AAC. It maintains the original filename but appends _converted before the .mp4 extension. The script can process individual files, multiple files, or all files within a specified directory. It logs the encoding duration and displays a notification upon completion.

Features

• Copy Video Stream: The video stream of the input file is copied directly without re-encoding.
• Convert Audio to AAC: The audio stream is converted to AAC with a bitrate of 160kbps.
• Filename Management: The output file retains the original filename with _converted appended before the .mp4 extension.
• Batch Processing: Capable of processing multiple files or all files within a specified directory.
• Performance Logging: Logs how long each file's encoding takes.
• Completion Notification: Displays a macOS notification with the encoding time upon completion.

Usage

To use the audio-fixer.sh script, navigate to the directory where the script is saved and run it from the command line. The script accepts individual file paths or a directory path with the appropriate flags.

./audio-fixer.sh [OPTION]... [FILE]...

Options

--help: Display detailed usage instructions and exit. Use this option if you need guidance or want to understand more about what the script can do.

--folder, -F: Specify this option followed by a path to a folder to process all video files within the specified folder. This is useful for batch processing multiple files at once.

Examples

To process a single file:

./audio-fixer.sh video.mp4

To process multiple specified files:

bash
./audio-fixer.sh video1.mp4 video2.mp4

To process all files in a specified folder:

./audio-fixer.sh --folder /path/to/folder

or alternatively, using the -F flag:

./audio-fixer.sh -F /path/to/folder

The script processes each specified video file by copying the video stream and converting the audio stream to 160kbps AAC. It outputs the processed file(s) in the same location as the input file(s), appending _converted before the file extension. A macOS notification is displayed upon the completion of each file, indicating the encoding duration.
