Question

您好我正在使用以下代码在Android上录制音频

myRecorder = new MediaRecorder();
myRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
myRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
myRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);
myRecorder.setAudioSamplingRate(44100);
myRecorder.setAudioEncodingBitRate(256);
myRecorder.setAudioChannels(1);
voiceFileName = getFilename();
myRecorder.setOutputFile(voiceFileName);

private String getFilename() {
    String filepath = Environment.getExternalStorageDirectory().getPath();
    File file = new File(filepath, "test");

    if (!file.exists()) {
        file.mkdirs();
    }
    return (file.getAbsolutePath() + "/" + System.currentTimeMillis() + ".mp3");

}

但是aac（.mp3）文件无法在iOS上播放。修改

let audioFilename = getDocumentsDirectory().stringByAppendingPathComponent("whistle.mp3")
let audioURL = NSURL(fileURLWithPath: audioFilename)
let whistlePlayer:AVAudioplayer = try AVAudioPlayer(contentsOfURL: audioURL)
whistlePlayer.play()

如何在IOS（Swift）中播放此文件？

Answer 1

我得到的解决方案只是将扩展名更改为.m4a，它可以在ios上运行

let audioFilename = getDocumentsDirectory().stringByAppendingPathComponent("voice.m4a")
let audioURL = NSURL(fileURLWithPath: audioFilename)
do
 {
   audioPlayer = try AVAudioPlayer(contentsOfURL: audioURL)
   audioPlayer.delegate = self
   audioPlayer.play()
 }
catch{
   print("filenotfound")
}

Answer 2

myRecorder.setOutputFormat（MediaRecorder.OutputFormat.MPEG_4）;建议你应该写入mp4（m4a）。不确定aac是否可以写入mp3容器

Answer 3

检查你是否可以在iPhone的Safari中播放该文件。你能告诉你怎么试着播放那个文件吗？
