3.1.3 Sampling Frequency
www.ti.com Basic Operating Set-Up—Windows Vista
Under the Windows Vista operating system, it is necessary to select a specific sampling frequency
because the sampling frequency cannot be changed on nearly all application software.
To set the DAC sampling frequency:
1. Open the Sound options from the Control Panel. ( Start → Control Panel → Sound)
2. Open the speaker properties of the USB audio codec from the Sound options and select the Advanced
tab, as Figure 3-5 illustrates.
3. Select the desired DAC sampling frequency from seven options: 8 kHz, 11.025 kHz,16 kHz, 22.5 kHz,
32 kHz, 44.1 kHz, and 48 kHz.
