How to publish a local audio stream using NetStream?

Question

As all we know, if we want to publish a stream to FMS or Red5, we can code like below:
var nc:NetConnection = new NetConnection();
nc.connect("rtmp://localhost/myApp");
var ns:NetStream = new NetStream(nc);
ns.attachAudio(Microphone);
ns.publish("audio", "live");
my problem is that we can pass an instance of Microphone to ns.attachAudio() only, if I want to attach a local audio stream,like playing a local sample.flv file to become a audio stream, how can I do?
this issue has been asked 7 years ago, see the post. but i can not find any solutions.
any tips will be appreciated. thx in advance.
