apache-flex - 如何过滤闪光灯(10.1)中来自麦克风的声音？

我从麦克风传来一些声音。我需要为其添加声音过滤器，然后将其播放给与该麦克风说话的人。
怎么做这样的事情？

最佳答案

据我所知，这可以通过空气完成:

这是满足您要求的示例代码:

import flash.media.Sound;
import flash.utils.ByteArray;
protected var soundRecording:ByteArray;
protected var soundOutput:Sound;
protected function playbackData():void
{
    soundRecording.position = 0;

    soundOutput = new Sound();
    soundOutput.addEventListener(SampleDataEvent.SAMPLE_DATA, playSound);

    soundOutput.play();
}

private function playSound(soundOutput:SampleDataEvent):void
{
    if (!soundRecording.bytesAvailable > 0)
        return;
    for (var i:int = 0; i < 8192; i++)
    {
        var sample:Number = 0;

        // apply your filter here
        if (soundRecording.bytesAvailable > 0)
            sample = soundRecording.readFloat();
    soundOutput.data.writeFloat(sample);
    soundOutput.data.writeFloat(sample);
     }
}
