FIGURE 12-1D A screen capture of Winrad showing that at 192-kHz
sampling frequency, tuning for radio stations spans 192 kHz.
In this example, 192 kHz of tuning range is available because of the computer's
sound card. Not all computers will come with this "extended" capability. For
example, many laptop computers will only allow for 48 kHz or 96 kHz of tuning
range. The user can first run Winrad to confirm the sampling rate and tuning range.
If the tuning range seems restricted, go to the Winrad top menu to select the
sampling rate (Figure 12-1E).
