Main display details

Details of the main display when you start LUCI STUDIO for the first time.Details of the fully loaded main display when you have setup the app completely and you are streaming. In the following pages we will explain how to set it up.

Echo server = chosen station
The Echo server is loaded by default. The Echo server is a free service and is meant for testing purposes only. You can use the Echo server to test your internet connection, the stream you send will be sent back, so you will hear yourself with a short delay. The server is located in a datacenter in Amsterdam, The Netherlands. Also, IPV6 will be used if available on your local internet connection. The first line shows the stations profile name, the second line the parameters used to setup the connection. To choose a new station simply tap on the first line. To add or edit a station see settings > stations.

Interview Simone (005) = the name of the file your live item is recorded to:

You can set the name of ‘the selected file to record to’ by tapping this area. For each new recording the number between the ( ) will increment and a new file will be written unless you change the name. As this is the fifth recording in this file the number 5 was added. For creating new recording files see Settings > Record to.

Interview Simone_003 = the name of the file you want to play or insert:

You can insert a pre-recorded file while broadcasting live. While playing this file the Mic signal will be muted. For inserting a pre-recorded file tap this area and or see Settings > Play from.

NOTE: The remaining play time indicator on the right is counting backwards.

OUT / IN Peak level meters = indicators of the signal levels

OUT: Indicates the level of the signal transmitted to the station generated from your MIC.

IN: indicates the level of the return signal from the station.

LUCI STUDIO integrates a software Limiter which protects the outgoing signal from clipping. If the limiter kicks in, the peak indicator will become orange, if the audio input overloads the peak indicator will become red.

Network jitter monitor:

The network jitter monitor is related to the amount of tolerable Jitter set-up in the application preferences. It indicates if the network jitter exceeds the tolerable value. By default this value is set to 100ms. Green = OK (below the tolerable value). Orange = the network jitter is close to the tolerable value. Red = the network jitter is exceeding the tolerable value.
When the jitter exceeds the tolerable value in LUCI STUDIO a short drop-out could be audible in the audio you hear from the incoming stream. The send stream could be unaffected and is shown at the “OUT” meter.
LUCI software tries to make drop-outs in the stream as inaudible as possible by interpolating missing audio.

Stream indicating LED:

The green light at the bottom left, this is the incoming stream indicator and can be gray, green, orange or red. (Green = OK, Gray = no incoming stream, Orange = data packet loss, Red = connection error). A packet loss does not necessarily mean you can hear this or something is seriously wrong. LUCI STUDIO will try to make errors inaudible. When the red light turns on intermittently every second or even turns gray (= no stream for a second), then the network conditions are too bad for a decent live report. When the orange light is often turned on, you could try to set the Jitter buffer longer or use the Dynamic Jitter option.

Mono / Stereo Indicators:

Additional information a “M” for Mono or a “S” for Stereo is shown, indicating the format of the in- or out- going stream.
