Does this question belong here?
I've never understood why. Well, I did learn once that muting prevents howl if a mic and a speaker get rather close together. [I]Is[/U] that the reason? The only reason?
Also I do not understand this. If mute basically means to silence, why am I able to record my voice in Dragon Naturally Speaking for example or in Windows Sound Recorder--with the mute box under 'Microphone' checked in XP's Play Control?
