    Hello,

    I'm trying to create a simple analogue audio amplifier and need to separate the positive and negative parts of the input signal. Is there a way to do this without introducing distortion for example when using two diodes? I was thinking of using two op amps with either power rail connected to ground but there must be a better way.

    A google search on "precision rectifier" should get you what you are after.
