What is the effect of pressure on the velocity of sound in air?

Humidity has little effect on the speed of sound, nor does air pressure by itself.
Air pressure has no effect at all in an ideal gas approximation.
This is because pressure and density both contribute to sound velocity equally, and in an ideal gas the two effects cancel out, leaving only the effect of temperature.
Sound usually travels more slowly with greater altitude, due to reduced temperature.

if the temperature is constant then there is no effect of pressure on the velocity of sound in air
