sound card. The second gives overview of input, and the third of output. If sound card is used as an audio measuring device than both input and output must be considered. In order to measure common audio devices, sound card should be able to measure frequencies to at least 20 kHz. Figure 2 shows measured frequency characteristics of

The sound card generates a stepped set of tones spanning a user-specified frequency range and number of steps (also entered into the setup window of AudioTester in the impedance measurement mode). The impedance measurement is performed by measuring the voltage across the known-value series resistor and the voltage across the load.

Here is the explanation from Audio Precision: The stimulus is a strong low-frequency interfering signal (f1) combined with a weaker high frequency signal of interest (f2). f1 is usually 60 Hz and f2 is usually 7 kHz, at a ratio of f1_f2=4:1. The stimulus signal is the sum of the two sine waves.

Sound Card for Audio measurement recommendations

Hi, I'm relatively ignorant about modern sound cards. I have built some mics based on the Panasonic WM-61A electret cartridge (Linkwitz mod) with an eye toward performing some system measurements.I have the RightMark RMAA 6 and audioTester by Ulrich Muller. The ancient sound card I tried first both with wouldn't work at all so I googled around a bit and after …

The best sound cards really can't do much better than about 10X that or .0003% (-110 dB) and then only when a lot of things have been carefully optimized. Output and input level limit the THD. Best results are at around -10 to -20 dBFS. THD and THD+N are different and THD+N is more difficult since any noise will limit the measurement.
