 2. The `is_adult` feature is not a definitive indicator of NSFW content:
    - It primarily indicates whether the audio comes from scenes included in the NSFW patch.
    - Casual conversations may still be present in adult scenes, so `is_adult = True` doesn't necessarily mean the audio should be categorized as NSFW.
-   - For Volume 3, there's currently no easy way to check if audio is from an NSFW part, so `is_adult` is set to `False` by default. Extra caution should be taken when using this data.
 3. Users should exercise discretion and additional verification when using the `is_adult` feature for content filtering or classification purposes.
