Audio Slicer

This is a simple command-line tool that can be used to split a video file into multiple audio files based on the timestamps provided in an SRT subtitle file. It also generates a corresponding list file with the text from the subtitle.

Requirements

• .NET Core 3.1
• FFmpeg

Usage

dotnet AudioSlicer.dll input-video.mp4 subtitle-file.srt output-directory/

• input-video.mp4: The path to the input video file.
• subtitle-file.srt: The path to the SRT subtitle file.
• output-directory/: The directory where the output audio files and list file will be saved.

Output

This tool generates two types of output:

1. Audio files: The audio files are saved in the specified output directory with a naming convention of audio-{timestamp}.wav, where {timestamp} is the timestamp of the subtitle entry in seconds. Each audio file contains the audio from the input video corresponding to the subtitle entry.
2. List file: The list file contains the text from the subtitle file along with the corresponding audio file name. The list file is saved in the specified output directory with the name list.txt.

Example

Suppose you have an input video my-video.mp4 and an SRT subtitle file my-subtitle.srt. You want to split the input video into audio files and generate a list file in the output/ directory. Run the following command:

dotnet AudioSlicer.dll my-video.mp4 my-subtitle.srt output/

The tool will generate multiple audio files in the output/ directory, such as audio-10.3.wav, audio-12.5.wav, audio-14.2.wav, etc. It will also generate a list file list.txt in the output/ directory, which will contain the text of the subtitle along with the corresponding audio file names.
