Due to this fact, there is a capability to calibrate a gain of the sound card to express amplitude with analogue units within the application. Since we can use a non-professional sound card, a ration between analogue and digital units is not known in advance when a measurement of external effect is done. For instance, a frequency characteristic can be obtained by exciting a device under a test with a logarithmic or a step harmonic sweep signal. For each of the analysis there is an option to select a suitable test signal. It is capable to generate harmonic signals such as sin or sweep signals and noise signals – MLS or white noise.

There is an internal signal generator within the application. There is an option to select if we want to analyze an external effect or a VST effect.

The software contains a graphical user interface where a user is able to set appropriate parameters for a measurement. The implemented analyses consider AES17 standard, which specifies parameters of test signals and parameters of filters that are used for analyses. The application is capable to measure frequency and linear characteristics, distortion parameters such as THD, THD+N, SINAD, WHD, a rate of crosstalk and a signal-to-noise ratio.
For the communication is used ASIO technology.
The hardware audio devices are connected to a personal computer via a sound card. The software allows to obtain qualitative parameters of hardware audio devices and software audio effects which are implemented in VST modules. It is possible to download software here.
