我想使用MediaPlayer循环播放此曲目,但它最终会产生这种奇怪的毛刺噪音,该曲目似乎在Audacity中工作正常并使用.OGG,我尝试使用SoundPool但我似乎无法工作
SoundPool pool = new SoundPool(1, AudioManager.STREAM_MUSIC,0);
AssetFileDescriptor lfd = this.getResourc es().openRawResourceFd(R.raw.dishwasherloop);
//mediaPlayer = new MediaPlayer();
try
{
//mediaPlayer.setDataSource(lfd.getFileDescriptor(),lfd.getStartOffset(), lfd.getLength());
//mediaPlayer.prepare();
//mediaPlayer.start();
int dish = pool.load(lfd,1);
pool.play(dish,0.5f,0.5f,1,-1,1.0f);
soundPool = new SoundPool(10, AudioManager.STREAM_MUSIC, 0);
soundPool.setOnLoadCompleteListener(new OnLoadCompleteListener()
{
public void onLoadComplete(SoundPool soundPool, int sampleId,
int status) {
loaded = true;
}
});
int soundID = soundPool.load(this, R.raw.dishwasherloop, 1);
soundPool.play(soundID, 0.5f, 0.5f, 1, 0, 1f);
答案 0 :(得分:2)
你需要搬家:
soundPool.play(soundID, 0.5f, 0.5f, 1, 0, 1f);
进入onLoadComplete处理程序,否则SoundPool会在实际加载之前尝试播放声音。所以像这样:
soundPool.setOnLoadCompleteListener(new OnLoadCompleteListener()
{
public void onLoadComplete(SoundPool soundPool, int sampleId, int status)
{
loaded = true;
soundPool.play(sampleId, 0.5f, 0.5f, 1, 0, 1f);
}
});
注意:传递给onLoadComplete处理程序的sampleId
是加载的soundId
。
此外,在SoundPool.play(...)中,您将循环标志设置为0,这意味着永远不会循环。如果您希望声音循环,则需要为-1:
soundPool.play(sampleId, 0.5f, 0.5f, 1, -1, 1f);
希望有所帮助。
