sound record

I have booked the sound studio for 3times and been there for 4. at first i dont know how to use the equipment there so we have to do it gain. after 3times working there, finally, i know how to work with those machines. and we finish the voice over. but the sound i took on the day of filming in not every good. It was rather windy and i need to record the sound of buses. so they are quiet nosiy. so we have to do it again.
