Hi I know in Audacity you can record a sound, invert it, and then play it, but I'm looking for something automatic.

Basically this program would listen to all sound coming in, invert them, and then play them at the same time. All instantly. Is this possible?

This will be nearly impossible. You will need ASIO or another driver with ultra low latency, and even then it might not be fast enough.

It would be much easier to get a pair of headphones that'll cancel out external audio by itself and play some music or gray noise through it.

I got myself a pair of Sennheiser CX300II expecially for this purpose. Will work with any device, including your smartphone.
