2. From the Default Device menu, select Sound booth 2.0 WDM Sound. 
3. Click Settings.
4. On the Input and Output tabs, set the following options:

Enable Devices

Determines which input and output ports are available in the Audio Hardware preferences.

Device 32‐bit Recording and Playback Enables 32‐bit inputs and outputs. To confirm whether a sound card supports this bit depth, see the documentation for the card. Buffer Size Specifies the number of audio samples buffered during recording and playback. If you hear skips or dropouts, increase the buffer size; if playback and recording start slowly, decrease the size.

Set properties for a DirectSound Card

If you have an older card that requires DirectSound, select this driver option.

If you hear skips or dropouts, double‐click the Buffer Size value for an input or output device, and type a higher value. If playback and recording start slowly, type a lower value.

Offset (Samples) Determines the audio latency (delay) between multiple sound cards. To enter a new value, double‐click the current one. 

Port Order

If the selected device includes more than one port, click the Move Up or Move Down button to change the order of the ports. 

Sync Reference 

In systems with multiple sound cards, specifies which card sets the master clock. (The master clock synchronizes digital audio devices.) 

Full Duplex

Enables Sound booth to simultaneously record and monitor audio. Leave this selected unless you have a very old sound card that doesn’t support full‐duplex operation. 

Start Input First

Determines the order in which Sound booth starts the sound card input and output ports. Select this option only if you have a very old sound card that doesn’t support full‐duplex operation.
