monkeyplug is a little script to mute profanity in audio files.

monkeyplug

monkeyplug is a little script to mute profanity in audio files (intended for podcasts, but YMMV) in a few simple steps:

1. The user provides a local audio file (or a URL pointing to an audio file which is downloaded)
2. The Vosk-API is used to recognize speech in the audio file
3. Each recognized word is checked against a list of profanity or other words you'd like muted
4. ffmpeg is used to create a cleaned audio file, muting the objectional words

You can then use your favorite media player to play the cleaned audio file.

If provided a video file for input, monkeyplug will attempt to process the audio stream from the file and remultiplex it, copying the original video stream.

monkeyplug is part of a family of projects with similar goals:

• 📼 cleanvid for video files
• 🎤 monkeyplug for audio files
• 📕 montag for ebooks

Installation

Using pip, to install the latest release from PyPI:

python3 -m pip install -U monkeyplug

Or to install directly from GitHub:

python3 -m pip install -U 'git+https://github.com/mmguero/monkeyplug'

Prerequisites

monkeyplug requires:

• FFmpeg
• Python 3
  • mutagen
  • vosk-api

• A Vosk-API compatible model in a subdirectory named model in the same directory as monkeyplug.py, or in a custom directory location indicated with the --model runtime option or the VOSK_MODEL environment variable

To install FFmpeg, use your operating system's package manager or install binaries from ffmpeg.org. The Python dependencies will be installed automatically if you are using pip to install monkeyplug.
