Why electret microphone with Op Amp circuit cause signal negative half wave to distort
Your virtual ground is formed by R3 and R8, and puts the bias point around 4.9V.  

At 25C, with a +/-15V supply, this amplifier is only guaranteed to swing within 3V of the rail.  

So 4.9-3V is 1.9V.  It's probable that the amplifier will distort before that point, and with your supply rails at -5V and +10V (due to your bias point being ~5V) it could make the available headroom worse, though there's no data on output swing under those conditions.
