How to change the pronunciation of vue

Vue.js is one of the most popular front-end frameworks today, allowing developers to build modern web applications faster. Among them, audio processing is a very important part of web development, and the voice changing effect is an important part of it. To implement the audio voice changing function in Vue, you can go through the following steps:

1. Determine the voice changing effect

First you need to determine the type of voice changing effect required, such as: pitch changing, mixing noise, distortion, etc., and determine the audio file length and sample rate to be processed as needed.

2. Introducing audio libraries

Introducing audio libraries into Vue applications can greatly simplify development work, because these libraries contain audio effects and algorithms that have been implemented before. Among the more commonly used audio processing function libraries are: SoundJs, Jsfxr, Pizzicato, Howler.js, etc. You can choose the appropriate audio library according to your needs and specific circumstances.

3. Load the audio file to be processed

In the Vue application, the audio file to be processed needs to be loaded. You can use the Audio object and Vue.js component provided by HTML5 Process it in a specialized development method. After converting the audio file into a component, use the life cycle function to initialize it.

4. Data processing

In the Vue application, you need to define a function for processing audio. This function contains the required audio library functions and parameters, and the audio to be processed The file is passed into the function for processing, and the processed audio file is returned.

For example, use the diaphragm effect function of the Pizzicato library:

function changePitch (audioFile, pitchFactor) {
   var sound = new Pizzicato.Sound(audioFile);
   sound.speed = pitchFactor;
   return sound;
}

5. View performance

Finally, define a playback component in the Vue application and add The processed audio file is passed to the playback component, which can be played through the view page. At the same time, the playback process can also be processed accordingly through Vue's built-in event listening function.

<template>
   <div>
      <audio
         ref="player"
         @play="onPlay"
         @pause="onPause"
         @timeupdate="onTimeUpdate"
         @ended="onEnded"
      ></audio>
   </div>
</template>

<script>
export default {
   props: {
      audioData: {
         type: Object,
         required: true
      }
   },

   data () {
      return {
         isPlaying: false,
         currentTime: 0,
         duration: 0
      }
   },

   methods: {
      play () {
         this.$refs.player.play();
         this.isPlaying = true;
      },

      pause () {
         this.$refs.player.pause();
         this.isPlaying = false;
      },

      togglePlay () {
         this.isPlaying ? this.pause() : this.play();
      },

      onPlay () {
         this.isPlaying = true;
      },

      onPause () {
         this.isPlaying = false;
      },

      onTimeUpdate () {
         this.currentTime = this.$refs.player.currentTime;
         this.duration = this.$refs.player.duration;
      },

      onEnded () {
         this.isPlaying = false;
         this.currentTime = 0;
         this.duration = 0;
      }
   },

   computed: {
      progress () {
         return this.duration ? this.currentTime / this.duration : 0;
      }
   },

   watch: {
      audioData: {
         immediate: true,
         handler (data) {
            this.$refs.player.src = URL.createObjectURL(
               data.blob || new Blob([data.buffer], {
                  type: 'audio/wav'
               })
            );
         }
      }
   }
}
</script>

Summary:

Audio voice changing is a very practical application scenario, and the method to implement this function in Vue is very simple. By introducing audio libraries, loading audio files, processing audio data, and defining playback components, it becomes easier to implement audio voice changing in Vue applications. The above is an introduction to voice changing in Vue.
