Thank you so much dutchjonnie.
Well yes this day there was some wind.but it was behind me so it was a little better because the wall cut the most of the wind.i used those little windscreens on the mics so the little wind that passing from the edges was mute.
But if the wind is strong you need more quality and bigger windscreens.
Well outdoor recording is a great thing becouse there are no reflection and the mics are working very nice but ...the wind always is a problem
Thank you again
