32 HOW TO EXPORT TRANSMITTED AUDIO
SmartSDR provides a means to export digitized audio that appears at the transmitter’s input. This
audio is exported to the DAX MIC channel where it can be connected to any program that opens a
sound card device.
The DAX MIC channel is controlled by the Mic Stream section of the DAX Control Panel:
The MIC stream is enabled and disabled by clicking the button in the upper left corner. The gain is
controlled with the slider.
The DAX MIC channel is supplied by the audio source that has been selected in the P/CW panel.
When the microphone or balanced input is selected, the audio received by the radio is digitized and
sent to the DAX MIC channel while the channel is enabled. When one of the other audio sources is
selected in the P/CW panel (e.g. LINE, ACC, PC) the audio is digitized and sent to the DAX MIC channel
only when the transmitter is active.
Audio is sampled and digitized before the Equalization and Processing steps are performed, so it
reflects the audio as presented to the radio. Since the DAX system runs independently of SmartSDR,
the audio connected to the DAX MIC stream is available from the stream even if SmartSDR is not
running.
