The regions plugin allows the user to create regions on the waveform of the audio by clicking and dragging. Today, I will share how I built an advanced audio player using WavesurferJS in NextJS.Īdditionally, I will also show how to use the regions plugin with wavesurfer. Audio files can be loaded from a remote URL or locally. backgroundColor: string: fff: The fill color of background. waveColor: string 999: The fill color of the waveform after the cursor. I need to switch the colors when I change the map type. Since the recordings are pretty long, rebuilding the entire wavesurfer.js object isn't that great. progressColor: string 555: The fill color of the part of the waveform behind the cursor. When Google Maps is in, I need a dark waveform, when it is in mode, I need a bright one. ![]() Wavesurfer is a JavaScript library that uses Web Audio API and HTML5 canvas to display and play audio files. The fill color of the cursor indicating the playhead position. It also emits helpful events like play, pause, end, seek, etc.īut if you want to build something more advanced like an audio editor, the audio tag isn’t sufficient. It supports looping, autoplay, mute, enable/disable controls, etc. It will only be this if the browser supports the Web Audio API. Note: you will have to check that analyser is an instance of AnalyserNode. The tag is supported by most modern browsers (IE too!) and has all the basic features required for an audio player. Looking at wavesurfer.js, you can get AnalyserNode using. cursorWidth: integer: 1: Measured in pixels. cursorColor: string 333: The fill color of the cursor indicating the playhead position. The first one is by simply including the script in your document from a CDN or a local copy: <- Load using a free CDN. According to the way you work, you can load this library in 2 ways. What I want is to use a different audio file for all my products.If you prefer a video over text, click here.īuilding an audio player has become fairly simple after HTML5. If specified, the waveform will be drawn like this: container: mixed: none: CSS-selector or HTML-element where the waveform should be drawn. Wavesurfer.js is a customizable audio waveform visualization, built on top of Web Audio API and HTML5 Canvas. So now it draws a waveform and has a play/pause button but the problem is that if I were to add a new product it would use the same demo song. Start using wavesurfer.js in your project by running npm i wavesurfer.js. barMinHeight: number: null: Minimum height to draw a waveform. Higher number than 1 will increase the waveform bar heights. barHeight: number: 1: Height of the waveform bars. barGap: number: none: The optional spacing between bars of the wave, if not provided will be calculated in legacy format. Latest version: 6.2.0, last published: 4 months ago. Change background color of the waveform container. ![]() A browser window will open to create a PR from this new branch to the. ![]() This will update the version, generate a changelog, and push everything to a new branch called release/X.X.X. git checkout master git fetch -all git reset -hard origin/master. Play: document.getElementById("btn-play"),ī("click", function() Interactive navigable audio visualization using Web Audio and Canvas. Switch to the master branch and make sure it's up-to-date. I added the following code to the product-template.liquid: This works like a charm, you can see it in action here (bottom of the product page). This change makes setWidth/setHeight return a boolean to indicate whether changes were needed. This now causes the waveform to be redrawn on top of the previous rendition, making the edges of the wave appear less crisp. I recently added an audio player on my product page using wavesurfer which draws a waveform based on the audio. In wavesurfer-js909 setWidth was changed to short circuit if the width did not change.
