The answer would depend on the direction of the wind. The sound waves propagated in the air would be pushed toward the observer when the wind was blowing toward the observer increasing frequency.

Explanation:

Frequency is the the number of waves reaching an observer per sec. Wind blowing toward the observer would push the sound waves toward the observer increasing the frequency or number of waves reaching the observer.

Wind blowing away from the observer would slow the waves down decreasing the frequency. The effect of any wind would be minimal. The speed of sound at 767 miles per hour is much greater than any normal wind speed and the increase or decrease of the speed of the wave would not be noticeable except with good quality scientific instruments.
