smartMetronome 🎵

Introduction

This demo uses flask, librosa, madmom, HTML/CSS/JavaScript to create a smart metronome app, targeting for musical instrument players who would like to record their performance and get a report with beat analysis. It's from Yi Shan's thesis project at NYU Music Tech Program.

How to run

Two ways to create a clean environment are provided, you can choose one of them. Based on the experience during test, if you already have conda installed, conda is recommended. If not, virtualenv is better.

Suggested Python Version: 3.8. Newer Version may bring lib conflicts.

Virtualenv method has been tested on Windows 11. Conda method has been tested on MacOS Sonoma.

Conda

cd ./smartMetronome

# Create conda env
conda env create -f environment.yml

# Check Python3 path. 
which python3 # The path is expected as something like /opt/anaconda3/bin/python3

# Check pip3 path.
which pip3 # The path is expected as something like /opt/anaconda3/bin/pip3

# Run app.
Python3 app.py

Virtualenv

# install virtualenv
pip install virtualenv

# create new virtual env
virtualenv venv

# activate env
//MacOS
source venv/bin/activate

//Windows
venv\Scripts\activate

# install requirements
pip install -r requirement.txt

# run
python3 app.py

If you start the server successfully, you will see the address in terminal. The default address should be: http://127.0.0.1:8080/ .

You can change host or port by editing app.py.

Usage

• Allow the mic authentication for the first time.
• Click Start button to start the metronome, the recorder will start at the same time.
• Playing some music 🎶
• Click Stop.
• You will see your recording showing at the right side of the website.
• Playback, or interact with the wave. If you are satisfied with it, click "Analyse".
• Loading... and then, you will see your report at the bottom!

FAQ

• "No module named 'Cython'", or "No module named 'Numpy'" while installing Madmom
  • Install Cython and Numpy manually. See requirements.txt for exact version.

Please note

• For now, there is always a delay after the recorder start. To avoid this temporarily, let the metronome tick for several seconds, then start playing.
• Any questions, please leave an issue.
