Cats, The Musical! Algorithmic Song Meow-ification
summary
An application called Meowifier takes an audio file and outputs the song’s melody sung by cat meows, implemented with Ruby and 100% TDD; melody extraction uses Sonic API (and trialed melodia), durations are adjusted with ffmpeg, and a multi-octave meow library plus looping/concatenation code fills long notes. The proof of concept works but sounds imperfect—melody extraction and meow artifacts cause too-many-or-too-few notes; a MIDI + soundfont pivot shows promise but is still crude.
