AI Audio Authenticity Checker
This tool evaluates audio files to detect whether they were likely generated by an AI system. It employs spectral analysis along with machine learning techniques to identify artifacts typical in AI-generated audio, such as pitch inconsistencies or spectral anomalies. Developers can use this tool to validate audio authenticity in media production or security applications.
What It Does
- Extracts audio features such as spectral centroid, bandwidth, rolloff, and zero-crossing rate.
- Generates spectrogram visualizations for audio files.
- Uses a simulated machine learning model to predict the likelihood of AI-generated audio.
Installation
To use this tool, you need to have Python installed on your system. Install the required dependencies using pip:
pip install librosa numpy matplotlib scikit-learnUsage
Run the tool from the command line with the following options:
python ai_audio_authenticator.py --input <path_to_audio_file> [--plot]Arguments
--input: Path to the input audio file (required).--plot: Optional flag to generate a spectrogram visualization of the audio file.
Example
python ai_audio_authenticator.py --input example.wav --plotThis will analyze the example.wav file and output the confidence score that the audio is AI-generated. If the --plot flag is provided, a spectrogram image will also be saved in the same directory as the input file.
