Everytime I use the audiowrite and audioread function, it adds some noise to my original signal. Does this happen just to me?

Frequency response plot of the signal before audio writing:

Frequency response plot of the signal after audio writing:

PS : The frequencies peaks of the signal are 20, 20.5 and 21KHz respectively.

The data is getting clipped on output because audiowrite() clips double values that are outside the range -1 to +1
