Audio Extract
A powerful, easy-to-use batch audio extraction tool wrapping FFmpeg. Extract specific segments of multiple audio files in one go, either via a graphical user interface (GUI) or a command line interface (CLI).
Features
- Batch Processing: Extract excerpts from all audio files (e.g., MP3, WAV) in a directory simultaneously.
- Dual Interfaces: Use the intuitive Graphical User Interface (GUI) or the automation-friendly Command Line Interface (CLI).
- Flexible Configuration: Define settings once in a
parameters.yamlfile, or override them dynamically in the CLI. - Fade Effects: Apply smooth fade-out/fade-in transitions to extracted clips.
- FFmpeg Integration: Auto-detects FFmpeg on your system PATH or allows specifying a custom path.
Prerequisites
- FFmpeg: Must be installed on your system.
- Download link: https://www.ffmpeg.org/
- Python: Version 3.7 or newer.
Installation
From Releases (Pre-built Wheel/Executable)
Download the latest wheels or standalone executable from Releases.
Usage
🖥️ Graphical Interface (GUI) - On Linux or Mac OS
The GUI allows you to select directories, adjust start/end times, toggle fade effects, and run extractions visually.
- Launch the GUI by running:
audio_extract_gui
- Choose the input folder, set your extraction duration, and click Process.
🖥️ Graphical Interface (GUI) - On Windows
- Download and run the standalone
audio_extract.exedirectly from the Releases page. - Choose the input folder, set your extraction duration, and click Process.
💻 Command Line Interface (CLI)
To run the CLI, navigate to your desired directory and execute:
audio_extract
By default, the CLI will look for a parameters.yaml file in the current directory to read configuration parameters.
Configuration File (parameters.yaml)
Create a parameters.yaml file in your working directory to customize the default run behavior:
input_dir: "input"
output_dir: "output"
first_second: 0
last_second: 120
input_file_extension: ["mp3", "wav"]
