Cheap audio THD tool
This card is good enough for relatively simple THD testing of audio power amps, which is what I needed it for. I use it to set the AC balance in my tube amps, so finding the null of each channels second order harmonic. Not suitable for 20 or 20KHz THD measurements being only 16/44.1 capable, need 24/96 minimum for that.
