How to use Vue to implement audio playback special effects

Introduction:
In web applications, audio playback special effects can increase the user's interactive experience and bring users More dynamic and interesting interface effects. Vue is a popular JavaScript framework that provides a wealth of functions and components that allow us to easily implement audio playback effects. This article will introduce how to use Vue to implement audio playback effects and give specific code examples.

1. Project preparation:

1. Create Vue project: First, we need to install Vue-cli and create a new Vue project. Execute the following command in the command line:

   npm install -g @vue/cli
   vue create audio-project
   cd audio-project

   Copy after login

2. Install the required dependencies: In the project root directory, execute the following command to install the required dependencies:

   npm install vue-audio-basics

   Copy after login
3. Create an audio file: In the project's public folder, create an audio file named audio.mp3 and make sure its path is public/audio.mp3 .

2. Implement audio playback special effects:
In this example, we will use Vue and Vue-audio-basics libraries to implement audio playback special effects. Vue-audio-basics is a Vue-based plug-in that provides some audio playback-related functions and instructions.

1. Introduce the required dependencies:
   In the project’s entry file main.js, add the following code to introduce Vue and Vue-audio-basics:

   import Vue from 'vue'
   import VueAudioBasics from 'vue-audio-basics'
   import App from './App.vue'
   
   Vue.use(VueAudioBasics)

   Copy after login

2. Writing audio playback component:
   Create a component named AudioPlayer.vue in the project, in this component, we will use v-audio command to implement audio playback effects. The following is a code example of the component:

   <template>
     <div>
       <audio
         ref="audio"
         :src="audioUrl"
         controls
         v-audio="{
           onPlaying: handlePlaying,
           onEnded: handleEnded
         }"
       ></audio>
       <p>{{ currentTime }} / {{ duration }}</p>
     </div>
   </template>
   
   <script>
   export default {
     data() {
       return {
         audioUrl: '/audio.mp3',
         currentTime: 0,
         duration: 0
       }
     },
     methods: {
       handlePlaying(audio) {
         this.currentTime = audio.currentTime
         this.duration = audio.duration
       },
       handleEnded() {
         this.currentTime = 0
       }
     }
   }
   </script>

   Copy after login

   In the above code, we bind the playback event of the audio file to the corresponding processing function through the v-audio directive. The onPlaying function will update the current time and total duration when the audio is playing, and the onEnded function will reset the current time when the audio playback ends.

3. Use the audio playback component in the main application component:
   In the App.vue component, you can use the AudioPlayer component to achieve this Audio playback effects. The following is a sample code:

   <template>
     <div>
       <h1>音频播放特效示例</h1>
       <audio-player></audio-player>
     </div>
   </template>
   
   <script>
   import AudioPlayer from './components/AudioPlayer.vue'
   
   export default {
     components: {
       AudioPlayer
     }
   }
   </script>

   Copy after login

3. Run the project:

1. Execute the following command in the command line to run the project:

   npm run serve

   Copy after login
2. Visit http://localhost:8080 in the browser, you can see the sample page of audio playback effects.

Summary:
By using Vue and the Vue-audio-basics library, we can easily implement audio playback effects. In this article, we introduce the specific project preparation work and give specific code examples for using Vue to implement audio playback effects. I hope this article has helped you use Vue to implement audio playback effects.
