+
+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.
