IO Settings Menu Command
The following IO setting dialog is used to define the input and output devices. The IO setting dialog is opened when input or output box is pressed in the configuration dialog. The dialog can be also opened from Config->IO settings menu.
Input parameters
Radio
If this is selected, the sound card (radio) is selected as an input signal source.
File (.wav)
When this is selected, a .WAV file is selected as an input signal source. The length of the file is limited to 60 seconds in the demo mode.
File (ASCII)
When this is selected, an ASCII file is selected as an input signal source. The length of the file is limited to 60 seconds in the demo mode.
Internet
When this is selected, the input data is read from the Internet. SkySweeper connects as a client to another SkySweeper, which works as server. SkySweeper asks IP address and port number, which are needed for connection. Note that you are able to connect to SkySweeper also in the same computer. In this case the IP address is 127.0.0.1. The user has to know the correct data format i.e. sample rate and bits per sample. If server uses decimation in order to decrease sample rate, a correct interpolation factor has to be defined.
Format parameters
8 bit
If this is selected, the format used in the input & output files and Internet connections is 8 bit.16 bit
If this is selected, the format used in the input & output files and Internet connections is 16 bit.
Rate parameters
11025
If this is selected, the format used in the input & output files and Internet connections is 8 bit.
22050
If this is selected, the format used in the input & output files and Internet connections is 16 bit.
Output parameters
Radio
If this is selected, the sound card (radio) is selected as an output .
File (.wav)
When this is selected, the .WAV file is selected as an output.
File (ASCII)
When this is selected, the ASCII file is selected as an output.
Internet
When this is selected, the Internet is selected as an output. LINKKI!
NULL
When this is selected, the NULL is selected as output. The signal is then not connected anywhere.
Internet Configuration Parameters
Internet as input
This dialog configures the Internet as an input signal source.
Parameters
IP Address
This is the IP address of the server machine running SkySweeper. Note that if the server has the firewall application in use, the connections from your machine IP address should be allowed. If you would want to connect another SkySweeper in the same machine, then the IP address is 127.0.0.1. User has to know beforehand the correct transmission parameters (sample rate, bits per sample and decimation factor).
Port
This is the port where SkySweeper server application is connected in the server machine.
Interpolation Factor
If the signal is decimated (=bandwidth is lower) in the server machine, then it should be interpolated with the same factor in the client machine. The possible values are (1, 2 and 4).
Internet as output
This dialog configures the Internet as an output signal destination.
Parameters
Info
This will show the IP address and the name of the machine.
Server Status
This shows the status of the server
Port
This is the port where SkySweeper server application is connected in the server machine.
Connections
This is the maximum number of the simultaneous clients using server.
Queue Length
This is the number of clients allowed to wait server services.
Connection Log File
All the connections (IP addresses etc) to the server (also failed) are written to the log file.
Decimation factor
This parameter limits the signal bandwidth with the given factor (1,2 or 4). It is used to minimize the amount of data transmitted over the Internet.
