Audio Spectrum and Formant Extraction by LPC on webs

Get a glimpse of this project

This project aims at drawing the following features for an input audio wav file:

• A sacalable time-domain waveform
• Custom frequency-domain spectra frame by frame
• Visualize the envelope of spectra and extract formants on the spectra through Levinson-Durbin LPC.

Get your hands dirty with it!

1. clone the project

  git clone https://github.com/haowang101779990/GraduationProject.git

2. In the cloned directory, open index.html in Chrome/Firefox.

Audio File input

I've put some wav. file already in ./sound_files. Just drag them into the input block

Drag your input audio file

Draw time-domain waveform :

Draw frequency-domain features: spectrum. envelope. formants.
