Is there any software that can be used a virtual microphone?

by virtual microphone, I mean a program which does not require any hardware and can play .mp3s or .wav and send it as the audio the mic would be sending.

I really do not know what you are trying to ask. Are you asking if you can record what your speakers are putting out? If so that's called recording "What U Hear" and is available on most sound cards. Use a program like Audacity to record.

What Baez said. Look for "What U Hear"... can also be like Stereo Mix.
