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.

Uses 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.
