what if any is the difference in sound between a recording and a live voice, between a voice on the telephone and the same voice live?
Let's say you heard your mother's voice in the next room. You couldn't see what was in there, and you knew it might be a recording or it might be her in there speaking live. Is there a difference in sound quality between recorded sound and live sound, so that you could know whether it is a recording or her live? If there is a difference how would you characterize it? People who are not audio experts are welcome to give their opinion.
