Hi Willaim Jia,
The calculation of Total Harmonic Distortion and noise (THD + N) of a signal is explained in this example. This requires the “Audio Toolbox” to be installed in MATLAB.
You can quickly open this example from MATLAB using the following command.
>> openExample('audio/THDNMeasurementWithTonetrackingExample')
For giving input from a wav file, you can use a From Multimedia block.
