Capture Channel Data Dialog
The capture dialog allows the user to start capturing digital audio samples from the channel and
forward the samples to a variety of destinations.
Clicking the Capture button from the content panel launches this dialog. This button is only
available if the displayed channel is connected.
Destination
• View signal display: This option displays the Signal display dialog and uses the audio
samples from this channel to drive the display. The signal can be displayed as a time
based signal or a spectral signal.
• Forward to remote host: Using this option, the audio data samples are forwarded via
socket to the remote host and port specified.
• File: If this option is selected, the audio samples are saved to file. Either type the full
path to the file or use the Browse facility to determine the file name.
Options
• Sample rate: Use the drop down box to specify either 8 KHz (default) or 16 KHz sample
rate for the data collection.
• Samples/Data packet: Specify the number of samples the NRC server should collect
before forwarding them to the client. The default is 640.
• Filter Option: If enabled, the server will filter the data through a 4KHz Low Pass Filter
before sending it to the client.
• Time Stamp: If enabled, the server will time stamp
5
each data packet with a TAI64N time
stamp representing the time that the last sample in the packet was captured. The default is
for there to be no time stamp.
5
If the NRC’s ntp is configured the time stamp will be in synchronized with the network time, otherwise this
timestamp will be synchronized to the NRC’s internal system clock.
