What I built

I built a local macOS beat-analysis app that imports MP3, WAV, and M4A files and explains a finished instrumental in approachable language.

Problem

A mixed beat can be hard to understand without production experience. Beat-to-Flow turns technical audio evidence into a readable map of tempo, structure, drums, bass, energy, and transitions.

Main features

Local drag-and-drop import
Tempo and beat estimates
Downbeats, bars, and sections
Kick, snare, hi-hat, and bass-change estimates
Transitions, drops, and pauses
Confidence-aware production explanations
Interactive timeline and audio playback
JSON, Markdown, waveform, and ZIP exports

Technologies

Python, FastAPI, librosa, NumPy, SciPy, SoundFile, FFmpeg, HTML, CSS, and JavaScript.

This is a private local case study. Beat-to-Flow runs locally on macOS and is not publicly available.
