|  | 
 | ||
|  | Select the *Audio* tab to configure your sound system. | ||
|  | 
 | ||
|  | - _Soundcard_: Select the audio devices to be used for *Input* and | ||
|  | *Output*.  Usually the *Mono* settings will suffice, but in special | ||
|  | cases you can choose *Left*, *Right*, or *Both* stereo channels. | ||
|  | 
 | ||
|  | - Be sure that your audio device is configured to sample at 48000 Hz, | ||
|  | 16 bits. | ||
|  | 
 | ||
|  | 
 | ||
|  | IMPORTANT: If you select the audio output device that is also your | ||
|  | computer's default audio device, be sure to turn off all system sounds | ||
|  | to prevent inadvertently transmitting them over the air.   | ||
|  | 
 | ||
|  | NOTE: Windows Vista and later may configure audio devices using | ||
|  | the Texas Instruments PCM2900 series CODEC for microphone input rather | ||
|  | line input.  (This chip is used in many radios with built-in USB | ||
|  | CODECs, as well as various other audio interfaces.)  If you are using | ||
|  | such a device, be sure to set the mic level in the Recording Device | ||
|  | Properties to 0 dB. | ||
|  | 
 | ||
|  | - _Save Directory_: _WSJT-X_ can save its received audio sequences as | ||
|  | `.wav` files.  A default directory for these files is provided; you | ||
|  | can select another location if desired. | ||
|  | 
 | ||
|  | - _AzEl Directory_: A file named `azel.dat` will appear in the | ||
|  | specified directory.  The file contains information usable by another | ||
|  | program for automatic tracking of the Sun or Moon, as well as | ||
|  | calculated Doppler shift for the specified EME path.  The file is | ||
|  | updated once per second whenever the <<ASTRODATA,Astronomical Data>> | ||
|  | window is displayed. | ||
|  | 
 | ||
|  | - _Remember power settings by band_: Checking either of these will | ||
|  | cause _WSJT-X_ to remember the *Pwr* slider setting for that operation | ||
|  | on a band-by-band basis.  For example, when *Tune* is checked here and | ||
|  | you click the *Tune* button on the main window, the power slider will | ||
|  | change to the most recent setting used for *Tune* on the band in use. |
