使用URL：http://lyd.nrk.no/nrk_radio_p1_ostlandssendingen_aac_h 代码：

Track *tr = [[Track alloc] init];
    tr.audioFileURL = [NSURL URLWithString:@"http://lyd.nrk.no/nrk_radio_p1_ostlandssendingen_mp3_l"];
    streamer = [[DOUAudioStreamer alloc] initWithAudioFile:tr];
    UIView *view = self.view;
    _audioVisualizer = [[DOUAudioVisualizer alloc] initWithFrame:CGRectMake(30, 30, 300, 300)];
    [_audioVisualizer setBackgroundColor:[UIColor colorWithRed:80.0 / 255.0 green:59.0 / 255.0 blue:74.0 / 255.0 alpha:1.0]];
    [view addSubview:_audioVisualizer];
    streamer.volume = 1.0;
    [streamer addObserver:self forKeyPath:@"status" options:NSKeyValueObservingOptionNew context:kStatusKVOKey];
    [streamer play];
