The project, built during paternity leave, aims to provide baby-friendly, slowed-down renditions of adult music. The tool currently produces imperfect but fun results, described as sounding like a 'drunk little music box version' of the original.", "body_md": "title basically covers it. project #2 from my paternity leave. My partner & I got frustrated with hearing Brahm's Lullaby and Wheels On The Bus repeatedly. I also stand by that babies can enjoy adult music just as easily as they can enjoy \"kids music\". But most adult music is too dense/complex for babies to understand, so I created this to generate baby-friendly, slowed down versions of songs that we like to play for our baby & sing along with.\n\nUses BS-roformer for stemming out the input audio + spotify Basic Pitch for transposing to midi. Still needs some work, kinda sounds like a drunk little music box version of the original but very fun.\n\nComments URL: [https://news.ycombinator.com/item?id=49338988](https://news.ycombinator.com/item?id=49338988)\n\nPoints: 1\n\n# Comments: 0", "url": "https://wpnews.pro/news/show-hn-ai-generated-music-box-version-of-any-song-for-baby", "canonical_source": "https://lullabyconverter.com", "published_at": "2026-08-17 23:14:35+00:00", "updated_at": "2026-08-17 23:41:08.661148+00:00", "lang": "en", "topics": ["generative-ai", "ai-tools", "artificial-intelligence"], "entities": ["BS-roformer", "Spotify Basic Pitch", "Hacker News"], "alternates": {"html": "https://wpnews.pro/news/show-hn-ai-generated-music-box-version-of-any-song-for-baby", "markdown": "https://wpnews.pro/news/show-hn-ai-generated-music-box-version-of-any-song-for-baby.md", "text": "https://wpnews.pro/news/show-hn-ai-generated-music-box-version-of-any-song-for-baby.txt", "jsonld": "https://wpnews.pro/news/show-hn-ai-generated-music-box-version-of-any-song-for-baby.jsonld"}}
