Pitch tracker explorer
First, have an instance of Gentle running. Follow the instructions on the Gentle page.
Then grab the dependencies for Drift and run it:
apt-get install ffmpeg
pip install -r requirements.txt
python serve.py --gentle_url <url for your gentle instance>
By default the server listens at http://localhost:9876.
The backend is written in Python. The frontend is written in JavaScript/React. Use webpack to build the JavaScript sources. Running webpack -p produces a minified production build.
This project makes it easy to see the F0 pitch of your audio recordings.
It uses the Python version of Dan Ellis's excellent Subband PCA algorithm (license MIT) for pitch tracking. It uses Gentle (MIT) for aligning audio with text.
You can use the web browser interface to upload, process, and view audio files with their pitch traces.
