Audible sound is in the range 20- 20000 Hz. Varying frequency gives the same velocity, since the medium is the same, i.e. air.
Thus, a larger frequency will cause a smaller wavelength and vice versa.
Examples: a high frequency sound is a bird chirping, while a drum beating is a low frequency sound. Both travel at same speed.
Result:
Speed of sound only depends on medium, which is air. We don't experiencea delay in sound when listening to birds or drums.
