Found-Sound Song Maker

Make a song using your own found sounds. Record taps, scrapes, voice noises, or anything that makes a sound — the app maps each sound to an instrument slot, then plays a real song using your sounds in place of instruments.

How it works

• Frontend — Next.js (App Router) at web/
• Backend — FastAPI in server.py, classifies and morphs sounds via pipeline.py
• Routes
  • / — morph mode: pick a song, fill slots, generate
  • /raw — raw mode: skip morphing, just pitch-shift to MIDI notes; temperature slider blends timbre
  • /studio — text-to-music mode (in progress)

Running locally
