Start LUCI Studio in your Start Menu

You will now see the main screen that you will use to work with.

Server at 5010

Tap on this field and you can choose the stations profile that you want to use from the phone-book.

rtp: 5010

shows information about the stations connection, like protocol (rtp) and portnumber (5010) when configured as server server, and other info depending on protocol.

OUT Level-meter

This is the audio level meter of the outgoing signal on the internet. Including a peak-hold.

IN Level-meter

This is the audio level meter of the incoming return signal. Including a peak-hold and a small “led” with 3 states: grey for no incoming signal, green for incoming signal without errors, and red when a receiving error was occurred.

Recording (000)

The name that will be used when you make a recording. Tap on this field and you can set the recording files prefix name. Each recording will have this prefix and an automatically added count number eg. Interview John Doo(001), Interview John Doo(002)….

00:00

The length of the current recording in minutes:seconds.

Play from… press me

Tap on this field for selecting a file to play, If you load a file for playing, its name will appear here.

00:00

The length of the file that’s loaded for playing.

‘Record-button’ (shown in the OFF-state ) to start a recording.

‘Play-button’ (shown in the OFF-state ) for playing a pre-recorded file.

‘MIC-button’ to activate the Microphone (shown in the OFF-state ) or Audio-input.

‘Antenna-button’ (shown in the OFF-state) to connect to your radio-server or start listening for incoming connections.

‘Menu-button’ .  Will show the pop-up menu window to access additional functions:

 

The menu items are depending on additional plugin features and are explained in detail in subsequent manual pages.

 

‘Info-button’ (shown in the OFF-state) to show an additional information window showing useful information on the set audio and streaming connection. This window will stick to the bottom of the main window and can be enlarged by dragging the bottom-right corner. In order to enlarge the first column click and drag the line between ‘Type’ and ‘Status’ column headers.

You can choose the font of the info window by right-click on the window, a menu will appear where you can choose an appropriate font.

Explanation of the additional Info:
Audio Input: currently chosen audio input
Outgoing Samplerate: Sample rate of the outgoing stream.
Outgoing codec: Codec format of the outgoing stream.
Incoming codec: Codec format of the incoming stream.
Incoming Samplerate: Sample rate of the incoming stream.
Audio Output: currently chosen audio output.
Estimated FPS: Number of packets/second of the incoming stream.
Dropped packets: Number of packets of the incoming stream that did not arrive.
Buffer underrun errors: Number of times that the jitter buffer was empty and nothing could be decoded anymore. Sequence errors: Usually there is too much jitter in the incoming stream then.
Connection time: Duration of the current connection.
Last connection IP: IP-address of the incoming stream.
Buffer status: Current status of the jitter buffer in number of packets available to decode.
Peak jitter: jitter measurement of the incoming stream in ms.
Video bitrate(kbps): Bitrate in kbps of an incoming video stream.
Skipped video frames: Number of video frames that did not arrive.

Connection Event Graphs ( CEG )

Items with a “triangle” in front of the value can be watched in time by means of a CEG. By clicking on the value field, a menu appears : 
The CEG can be switched on to display the events with an average of 1, 10,60 seconds or in Real Time ( every measured sample ). You can also save these values to a spreadsheet (.csv) Log file for analysis. The files are saved in a subdirectory in Documents\LuciStudio-Logs\CEG\ and will produce a file on every connection. If during that connection no serious events occur, then you can choose to remove the file by selecting “Log only Issues”. The current Log file can be directly opened by selecting “Open Log File”. An installed spreadsheet program will then handle the “commas separated value” file import and viewing.

When the CEG is switched on for a value, it’s “triangle” is black, if it is also saved to a file, it becomes a black “dot”. The Graphs have blue ruler time periods at a meaningful distance: every 10 seconds (dotted line) and per Minute (straight line) or every Minute/Hour, depending on the average time set. The length of the graphs are as long as the Info window is wide. The Graphs are automatically scaled to the maximum measured value. If there are some problems detected it will colour these events red.

Error events ( like dropped packets) are shown as change events, differently than measured events ( like Peak Jitter ) that are shown by their value.

The graphs and files can be a help for detecting issues that only occur sometimes, like a to small jitter buffer: if you see to many red issues in the Maximal jitter values graph than a fix would be to increase the jitter buffer or add an dynamic jitter buffer ( Stations setting ).
