https://forums.ni.com/t5/LabVIEW/How-to-do-simple-audio-measurements-with-a-sound-card/td-p/3361800
Hello, I would like to do simple audio measurements (level, THD, frequency) in LabVIEW with a sound card. The audio signal is a simple analog 1kHz sine tone. I know it's better to do this with a real audio analyzer, but this would be a significant investment. So how can this be achieved with a sta...

By using many audio samples, we are able to gain in the order of 32 db or so in noise reduction (called "FFT gain"). This allows us to dig deep to as low as -150 db looking for distortion products. This floor is well in excess of hearing dynamic range (around -116 dB). Unfortunately this FFT gain is source of a lot of confusion.
