Fourier Synthesizer Web Component
This project is a standalone Web Component for generating waveforms and audio using Fourier synthesis.
It was originally inspired by a Java Applet created by Manfred Thole.
Demo
Features
- Waveforms can be saved and loaded via JSON files
- Real (cosine) and imaginary (sine) harmonic adjustment
- Adjustable fundamental frequency
- Unlimited number of harmonics
- Controls operate in real time
- Configurable graph options
- Fully customizable feature set including graph colors
- All text fully translatable (English is built-in)
Develop
For information about development using this project see DEVELOP.md.
Use on the web
To use the Fourier Synthesizer web component on your web site, you need to import the component as a script and add the custom element tag to your page(s).
Browser support
Firefox (as of v112) and Safari (as of v16.3) do not support the disable normalization feature of the Web Audio API. As a result, the DC Offset control will not work properly - it is not possible to "clip" the generated wave where it exceeds the maximum level (the limits of the graph area). For best results use a different browser such as Edge, Opera, or another Chromium variant. For more information on browser support see the MDN documentation.
Script import
Add a script tag to the <head> section of your page. Replace https://my.domain/server-path/fourier-synth/ shown below with the path where the component files are stored on your server or elsewhere.
<script type="module" src="https://my.domain/server-path/fourier-synth/fourier-synth.esm.js"></script>Hosting
Download one of the deploy files fourier-synth@1.1.1.zip or fourier-synth@1.1.1.tgz, and extract the contents. (The tgz file contains a tar file that needs to be extracted.) The extracted fourier-synth folder should be copied to your server including all contents. The name of the folder is not important, but it must match the src value of your page's script tag, and the file names must not be altered.
Serving from unpkg.com
If you don't need guaranteed availability, you can use the component from unpkg.com.
<script type="module" src="https://unpkg.com/fourier-synth@1.1.1/dist/fourier-synth/fourier-synth.esm.js"></script>Element tag
Add the element somewhere on your web page. Remember to use style or layout to control the size of the component.
<fourier-synth style="width: 850px;">Please enable JavaScript to use Fourier Synthesizer</fourier-synth>Customization
To customize the features of the component or translate into another language, see the readme file for the web component.
