使用示例

<script setup>
import { ref } from 'vue';
import SoundWave from './components/SoundWave/SoundWave.vue'
const mkRef = ref(null);
const isRecord = ref(false);
const handleToggle = () => {console.log('handleToggle', mkRef.value);mkRef.value.togglePlay();isRecord.value = !isRecord.value;
};
</script><template><button class="control-btn" @click="handleToggle">START</button><SoundWave ref="mkRef" :isRecord="isRecord"></SoundWave>
</template><style scoped>
.control-btn {background-color: #4CAF50; border: none; color: white; padding: 10px 20px; text-align: center; text-decoration: none; display: inline-block; font-size: 16px; margin: 4px; cursor: pointer; border-radius: 4px; transition: background-color 0.3s ease; 
}.control-btn:hover {background-color: #45a049; 
}
</style>

npm下载该功能

上面功能可以直接去我的npm主页下载

npm i vue-sound-wave

说明

只针对麦克风音波效果开发，不做音频文件导出
