"""
Voices were cloned using metadata-balanced.csv, but not all voices were cloned successfully.
Here, we create a JSON file mapping of available audio files to the TTS models that generated them.
The JSON file is currently used in the clone-guesser gradio app, so we keep it for now.
We then use the mapping to filter out for audio files that are available for all models.
The filtered metadata is then saved to a CSV file, "metadata-valid.csv".
