Wavesurf JS - JavaScript

Introduction

Wavesurf JS is a JavaScript library that provides an easy-to-use waveform visualisation for audio files. It is responsive, interactive and customizable, making it a great tool for developing audio-related applications.

Features

• Renders waveform with customizable colors, heights, and widths
• Displays song progress and allows users to seek through the song
• Provides useful methods for manipulating and accessing audio data
• Supports multiple audio file formats
• Simple and intuitive API

Installation

You can install Wavesurf JS using npm:

npm install wavesurfer.js

Alternatively, you can also include it in your HTML file using the following code:

<script src="https://unpkg.com/wavesurfer.js"></script>

Getting started

Once installed, you can instantiate a Wavesurf JS object and load an audio file as follows:

const wavesurfer = WaveSurfer.create({
    container: '#waveform',
    waveColor: 'red',
    progressColor: 'purple'
});

wavesurfer.load('path/to/audio/file.mp3');

Here, we create a new WaveSurfer object, set the container to a DOM element with the ID waveform, and specify the colors of the waveform and progress bar. We then load an audio file using the load() method.

Customization

Wavesurf JS allows customization of many aspects of the waveform display. For example, you can change the color gradient of the waveform, adjust the heights and widths of different elements, and add markers and regions to the waveform.

Useful methods

Wavesurf JS also provides several useful methods for manipulating and accessing audio data. For example, you can get the current playback time, seek to a specific time, and zoom in and out of the waveform.

Conclusion

Overall, Wavesurf JS is a powerful and flexible tool for visualizing and manipulating audio data. Whether you are building a music player, a sound editing app, or an audio analysis tool, Wavesurf JS can make your development process easier and more efficient.
