AudioTrack:如何检测声音结束？

const int SAMPLE_RATE = 44100;
const int BUFFER_SIZE = 8192;

AudioTrack audioTrack;
short[] audioData = new short[BUFFER_SIZE];

void setup() {
  audioTrack = new AudioTrack(AudioManager.STREAM_MUSIC, SAMPLE_RATE, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, BUFFER_SIZE);
  audioTrack.setVolume(1.0f);
  audioTrack.setLoopPoints(0, BUFFER_SIZE / 2, (short) (SAMPLE_RATE * 1000));
}

void loop() {
  audioTrack.write(audioData, 0, BUFFER_SIZE);

  if (audioTrack.getPlayState() == AudioTrack.PLAYSTATE_STOPPED) {
    // 声音已停止播放，可以认为声音已结束
    // 在这里执行声音结束后的操作
  }
}
