ADC Channel Listening
via a sound card
When working with measurement objects in real conditions or through signal reproduction from the recorded files, the user can listen to the data coming to the input channels of ADC modules and FFT Spectrum Analyzers via the PC sound card, which can be very useful during signal analysis in an acoustic range, since spectral analysis cannot always provide proper information about the analyzed values. For instance, distortion due to a short-term interference will be well audible for a human, while 1/3-octave analysis will not introduce any noticeable changes in the signal spectrum. This is due to the fact that the human ear, as compared to the analyzing instruments, can identify parasite sound sources much more distinctly.
For further analysis of acoustic information, it is possible to listen to the recorded signal time realizations in the analogue tape recorder mode.
