2. Select audio device for alert audio file recording
The DASDEC Encoder provides an interface to record audio into WAV files (EG. the audio file recording
interface is available under the Encoder > Send EAS > General EAS web page). These files can then be
used for the voice audio portion of an EAS alert. This page provides for selecting which audio device and
input source (microphone or line input) is used for the recording.
NOTE: An active link to this page is provided wherever the audio recording
interface is presented.
Use the ALSA sound system when directly recording WAV files on the DASDEC. ALSA supports a mic
boost that results in clearer, louder, audible recordings.
Sound card source - The standard DASDEC provides one Auxiliary Audio card in addition to the Main
audio card. When more than one sound card device is present, a radio button selection option for the
recording sound card will be displayed. Select the card to use as the recording source.
Input Source - Once the source sound card is selected, set the Input Source to either Microphone Input or
Line Input Left. The selection is determined by the actual source from which you will record.
Record Input Level - Use the Input Level control to set the level for the recording input gain level. Enter a
value from 0 - 100 in the Record Input Level field. After you set the value, you must click on the text
here to activate changed
NOTE: During recording, the DECODERS on the selected audio card
source are DISABLED!
