Hi friends,
I'm finding how to know my am
plifier performance in term of THD.
I used the sound card oscilloscope software then my amplifier is about 0.02% @2w and 0.4% @full power.
Are there any another way to do like this with more accurate because of even measured the input signal it shows 0.01%.

Have you tried the free demo version of RMAA, 1st in loopback mode to test your soundcard?
