An analysis and synthesis algorithm for quasi-periodic signals, e.g. vowels.
The HarmSyn package has two components that make up its functionality.
- The analysis component tracks the instantaneous frequency of a harmonic signal and measures the amplitudes of its harmonics at regular time intervals.
- The synthesis component re-synthesizes the harmonic signal based on its fundamental frequency and the amplitudes of its harmonics at each time point.
The Git repository consists of three parts.
- root: The JavaScript NPM package containing the algorithm.
- harmSynApp: A browser-based web application.
- harmSynCli: A Node-based command-line tool.
