使用AS3工作人員錄製聲音

Question

你好我正在嘗試使用AS3 Worker錄製用戶聲音當涉及到工作人員和主場景之間的通信時，一切都很好，但我認爲錄製功能有問題並且在這裏發佈我正在使用Record從bytearray.org（http://www.bytearray.org/?p=1858） 這裏衝突的IS我的代碼，我失去的東西：

看着this write-up on Adobe's AS3 reference，似乎因爲每個創建的工作是「一個虛擬 Flash運行時的實例」，它有任何的核心運行時的輸入或輸出通道的沒有直接的聯繫。麥克風類是一個這樣的截止界面，這就是爲什麼它不能到達工作人員內部的系統麥克風。
