Did you mean to have the mics a little closer to one another?
Yes. It's better to my taste here. But the signal-to-noise seems lower. Very nice bird songs in the background.
I put the mics a little closer to one another and I now have them both in an upright position. I had them in a horizontal position parallel with the floor but am not sure if this is the right thing to do.
The active face of the microphones should be steered to the piano. Otherwise, this may explain why the signal-to-noise ratio is low.
