方法一:格式轉換(水平和時間有限,而且操作麻煩,暫時放棄)
方法二:使用 benz-amr-recorder(推薦)
- 下載和引入(我用的vue所以直接npm)
npm install benz-amr-recorder
const BenzAMRRecorder = require('benz-amr-recorder')
- 初始化
let amr = new BenzAMRRecorder();
amr.initWithUrl(url).then(function() {
amr.play(); 播放
});
- 我用element+vue模擬了一個進度條,大致效果如下
- 補充一個完整代碼,僅爲彈框播放組件代碼,組件支持’audio’, ‘video’, ‘img’, ‘file’,

- 用到的相關API
- 整合 play() 和 resume() 和 pause() //播放狀態會暫停,暫停狀態會播放
amr.playOrPauseOrResume();
- 獲取當前播放位置(秒)
amr.getCurrentPosition();
- 獲取音頻的時間長度(單位:秒)
amr.getDuration();
- 播放結束時觸發
amr.onEnded(function() {
console.log('播放結束');
});
總結:做了個簡單版本,如果發現問題可以發出來溝通交流
