我使用 ActionScript 3 构建了一个在 Desktop 中录制声音的应用程序,现在我将应用程序转换为 Andriod 应用程序,但是存在 SampleDataEvent.SAMPLE_DATA 事件没有接收到任何要记录的数据的问题这是代码:
private var _microphone:Microphone;
private var _buffer:ByteArray = new ByteArray();
private var _difference:uint;
public function record():void
{
if ( _microphone == null )
_microphone = Microphone.getMicrophone();
_difference = getTimer();
_microphone.setSilenceLevel(_silenceLevel, _timeOut);
_microphone.gain = _gain;
_microphone.rate = _rate;
_buffer.length = 0;
_microphone.addEventListener(SampleDataEvent.SAMPLE_DATA, onSampleData);
_microphone.addEventListener(StatusEvent.STATUS, onStatus);
}
private function onSampleData(event:SampleDataEvent):void
{
_recordingEvent.time = getTimer() - _difference;
dispatchEvent( _recordingEvent );
var buteData:Number;
while(event.data.bytesAvailable > 0)
{
buteData = event.data.readFloat();
_buffer.writeFloat(buteData);
soundBytes.writeFloat( buteData);
}
}
任何人都可以在这里提供帮助
